Description

[Technical field]

[0001] The present invention relates to a method for producing an imitation seafood food. [Background technology]

[0002] In today's world where diversity is being loudly proclaimed, there are many different dietary principles and tastes. For example, there are vegetarians who do not eat meat, but the term vegetarian does not only include vegetarians who consume eggs and milk, but also vegans who do not eat any animal-derived foods at all.

[0003] Even vegans sometimes want to eat foods other than vegetables, etc. To satisfy such desires, imitation foods that resemble animal-derived foods but do not use animal-derived ingredients, such as those described in Patent Document 1, have been developed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-159076 Summary of the Invention [Problem to be solved by the invention]

[0005] Many imitation foods have been developed. However, until now, seafood imitation foods that resemble fish and shellfish have not been able to fully reproduce the muscles that are unique to seafood. As a result, conventional seafood imitation foods have not satisfied the visual desires of consumers. In addition, although attempts have been made to incorporate muscles between the flesh in order to reproduce the muscles, the muscles and flesh of the resulting imitation foods tended to come apart easily, making them of insufficient quality for distribution.

[0006] To provide a method for producing an imitation marine food, which can reproduce the flesh of a marine food with higher reproducibility than conventional methods and in which the tendons and flesh are not easily separated from each other. [Means for solving the problem]

[0007] The inventor discovered that by forming a layer of muscle fluid, which has a different viscosity from the muscle fluid, on top of a layer of fish fluid, passing a blade through this layer of muscle fluid to make an incision in the layer of fish fluid, and then removing the blade to allow the muscle fluid to enter the incision, it is possible to produce an imitation seafood food with veins just like real seafood, and thus completed the present invention.

[0008] Therefore, the present invention provides a method for producing an imitation seafood food containing dietary fiber, comprising the steps of: Mixing dietary fiber and a first thickener in water to prepare a thickening solution; forming a layer of said base liquid; preparing a muscle fluid containing titanium dioxide and / or calcium carbonate and a second thickening agent and having a different viscosity than the muscle fluid; forming a layer of the myocardial fluid on the layer of the myocardial fluid; Inserting a blade from above the layer of myocardial fluid, and using the blade to make an incision through the layer of myocardial fluid into the layer of myocardial fluid; The blade is removed and the muscle fluid is inserted into the incision in the layer of muscle fluid; solidifying the body fluid and the muscle fluid; The present invention provides a method for producing an imitation seafood food, comprising:

[0009] The present invention also provides a method for producing the above imitation seafood food, wherein the fish meat liquid is further prepared by mixing it with tapioca powder and / or lycopene.

[0010] The present invention also provides a method for producing the above-mentioned imitation seafood food, which further comprises solidifying the flesh liquid and muscle liquid and then freezing the solidified product.

[0011] The present invention also provides a method for producing the above imitation seafood food, wherein the fish meat liquid is further adjusted by mixing it with a vegetable ingredient. Effect of the Invention

[0012] By forming a layer of muscle fluid with a different viscosity from the muscle fluid on top of the muscle fluid, passing the blade through the muscle fluid layer to make an incision in the muscle fluid layer, and then removing the blade to allow the muscle fluid to be inserted into the incision, it is possible to produce an imitation seafood food with veins just like real seafood. Furthermore, by adding tapioca and lycopene to the muscle fluid and freezing it after it has solidified, it is possible to reproduce the color, opacity, and texture of red tuna.

[Figure 4] FIG. 4 is a flow chart of another example of the method for producing an imitation seafood product according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, some examples of the method for producing an imitation seafood product according to the embodiment will be described with reference to the drawings. However, the method for producing an imitation seafood product according to the present invention is not limited to the examples described below.

[0015] First, an example of a method for producing an imitation seafood food according to the present invention will be described with reference to Figures 1 to 3. The imitation seafood food according to the present invention is produced by preparing a fish meat solution and a muscle solution, and inserting the muscle solution between the fish meat solutions.

[0016] <Preparation of the body solution> First, the dietary fiber and the first thickener are mixed with water to obtain a mixture. This mixture is called the body solution.

[0017] The dietary fiber may be, for example, water-soluble dietary fiber. In this specification, the water-soluble dietary fiber is a dietary fiber that dissolves in an aqueous solution, and includes dietary fiber that has the property of increasing the viscosity of the aqueous solution by dissolving in the aqueous solution. The water-soluble dietary fiber used in the present invention may be, for example, glucomannan (e.g., konjac root), dietary fiber derived from seaweed (e.g., agar), and chemically modified polysaccharides (e.g., modified starch), but is not particularly limited thereto. Glucomannan is a polysaccharide present in konjac root. Glucomannan can be obtained as konjac flour, for example, by drying and grinding konjac root and separating impurities. Konjac flour contains about 75 to 85% by mass of glucomannan. Commercially available glucomannan products can be used.

[0018] The amount of dietary fiber can be adjusted so as to obtain the desired hardness and viscosity in the imitation seafood food, and can be, for example, from 0.3 to 10 parts by weight, and preferably from 0.5 to 7 parts by weight, per 100 parts by weight of the fish meat solution.

[0019] The first thickener is not limited as long as it is a food thickener. The thickener can be, for example, methylcellulose, locust bean gum, guar gum, gellan gum, carboxymethylcellulose, gum arabic, xanthan gum, corn starch, carrageenan, and pectin. The amount of the thickener can be adjusted so as to obtain a desired hardness and viscosity in the seafood imitation food, and can be, for example, 0.3 parts by mass or more and 5 parts by mass or less, and preferably 0.5 parts by mass or more and 3 parts by mass or less, relative to 100 parts by mass of the fish meat solution.

[0020] Tapioca powder can also be added when preparing the flesh solution. Tapioca powder is a starch powder produced from the rhizome of cassava. By including tapioca powder in the imitation seafood food, not only can the white color of seafood be reproduced, but also the color of seafood flesh can be reproduced by using tapioca powder in combination with other color formers. The imitation seafood food containing the tapioca powder of the present invention can be colored white by freezing after solidification.

[0021] The amount of tapioca powder can be adjusted so that the desired whiteness, hardness and viscosity are obtained in the imitation seafood food, and can be, for example, 1 to 10 parts by mass, preferably 2 to 8 parts by mass, per 100 parts by mass of the fish paste liquid. The tapioca powder may also be provided as a solution by mixing the powder in a solution such as water, or the tapioca powder may be provided by heating and dissolving it in the solution.

[0022] In addition to the tapioca powder, another coloring agent can be added during the preparation of the batter solution. The other coloring agent can be any coloring agent that produces a desired color, including, but not limited to, lycopene pigment and paprika pigment.

[0023] By adding lycopene pigment, the texture of red tuna meat can be reproduced. The texture of red tuna meat can be reproduced. Lycopene pigment can be added in an amount of 0.01 to 3.0 parts by mass, for example, 0.05 to 0.5 parts by mass, per 100 parts by mass of the meat solution. By including lycopene pigment in such an amount, the white color of the tapioca powder and the red color of the lycopene pigment can be combined to reproduce the color and texture of red tuna meat.

[0024] The lycopene pigment can be, for example, tomato pigment. The lycopene pigment may be added as a mixture with other ingredients. For example, the lycopene pigment can be added as a mixture of glycerin, food ingredients (e.g., water), sucrose fatty acid ester, lecithin, and tomato pigment as the lycopene pigment.

[0025] On the other hand, by further adding paprika pigment in addition to lycopene pigment, the texture of salmon trout meat can be reproduced in the seafood imitation food. The paprika pigment can be used in an amount that reproduces the desired meat color, for example, 0.01 to 3.0 parts by mass, for example 0.05 to 0.5 parts by mass, per 100 parts by mass of the meat solution. By including lycopene pigment and paprika pigment in such amounts, the color and texture of salmon trout meat can be reproduced by the effect of the white color of the tapioca powder, the red color of the lycopene pigment, and the orange color of the paprika pigment. Furthermore, by adding titanium dioxide to the mixed solution, the texture of salmon trout meat in the seafood imitation food can be reproduced more easily.

[0026] The paprika color may be, for example, a capsicum color. The paprika color may be added as a mixture with other ingredients. For example, the paprika color may be added as a mixture of a food ingredient (e.g., water), mixed tocopherols, and a capsicum color as the paprika color.

[0027] The fish meat solution may further contain optional additives to impart a desired flavor to the imitation seafood food. In particular, by adding vegetable ingredients, the texture of the imitation seafood food can be imitated to mimic seafood, while the taste of vegetable soup can improve the taste of the imitation seafood food. The inventors have surprisingly found that the flavor of the imitation seafood food can be improved by adding vegetable ingredients different from fish.

[0028] The vegetable ingredients may be in liquid or granular form. In the case of liquid, i.e. vegetable soup, it may be of animal origin, such as bouillon, but it may also be animal-free for vegans.

[0029] Vegetable soup may contain, for example, water, soy sauce, sugar, salt, fermented seasoning, vegetables (onion, celery, carrot, etc.), and yeast extract, but the ingredients are not particularly limited.

[0030] The fish meat solution may also contain other ingredients. The fish meat solution may also contain hydroxypropyl starch, for example, to enhance storage stability. The fish meat solution may also contain, for example, potassium chloride, as an anti-caking ingredient. The anti-caking agent is necessary when storing the powder formulation and is mixed into the raw materials. The raw materials for producing the seafood imitation food of the present invention may contain an anti-caking agent, and therefore the seafood imitation food may contain an anti-caking agent. In addition, glucose and dextrin, etc. may be added to the fish meat solution to give the seafood imitation food a chewy feel and a chewy texture. In addition, the fish meat solution may contain further ingredients to reproduce a desired color.

[0031] <Mixing of body fluids> The batter solution can be prepared by any procedure. Simply, it can be prepared by mixing dietary fiber and a first thickener in water. Alternatively, the batter solution can be obtained by mixing other ingredients together, such as tapioca powder and lycopene.

[0032] The container for mixing is not particularly limited. For example, by using a kettle such as a temperature-adjustable electric kettle, mixing and the subsequent heating can be performed in the same container.

[0033] When preparing the batter solution, a first mixture obtained by mixing dietary fiber with a thickener and water and a second mixture obtained by mixing tapioca powder with a thickener and water may be mixed to produce the mixture.

[0034] In addition, when preparing the fish meat solution, each component can be mixed at any temperature. However, if the materials are simply mixed in water, the materials will not be sufficiently dissolved and lumps will form. In order to prevent the formation of lumps in the materials, the mixing temperature can be set to 1°C or higher and 30°C or lower. Alternatively, in order to prevent the formation of lumps in the materials, the mixed liquid may be produced while stirring the raw materials in water using a high-speed stirrer. In addition, when preparing the fish meat solution, it is preferable to heat the mixture after mixing. It is preferable to heat the mixture to a temperature at which the mixed fish meat solution components dissolve, for example, a temperature of 85°C or higher and 100°C or lower. By heating the fish meat solution, the color of the seafood food to be imitated can be reproduced more closely. It is preferable to heat and mix the mixture. The temperature for heating and mixing is preferably 60°C or higher, and more preferably 75°C or higher and 100°C or lower.

[0035] The fish meat solution may be heated to a temperature above the melting point of each of the raw materials, i.e., dietary fiber, tapioca powder, thickener, and coloring agent. If the fish meat solution is not heated to a temperature above the melting point of each of the raw materials, water will be released when the seafood imitation food is frozen and thawed in a later step. Therefore, the method for producing the seafood imitation food of the present invention may further include heating the fish meat solution after preparing the fish meat solution.

[0036] When a coloring agent other than tapioca powder is added, the coloring agent is mixed after heating, and the coloring agent does not become the desired color. Therefore, when a coloring agent other than tapioca powder is added, it is preferable to heat the fish meat solution obtained by mixing the coloring agent with other materials. When heating, it is preferable to heat the fish meat solution so that the temperature is between 85°C and 100°C. Coloring agents such as tapioca powder, lycopene pigment, and paprika pigment can be heated in the fish meat solution to improve color development, and the color of the seafood to be imitated can be more easily reproduced.

[0037] After heating, the body solution has a viscosity that gives it fluidity. The viscosity of the body solution changes depending on the temperature. The higher the temperature of the body solution, the lower the viscosity, since each component is dissolved by heating. The viscosity of the body solution can be 10 dPa·s to 500 dPa·s, for example 50 dPa·s to 200 dPa·s, for example 60 dPa·s or more and 150 dPa·s, when the solution temperature is, for example, 60°C to 100°C. The viscosity of the body solution can be 10 dPa·s to 500 dPa·s, for example 50 dPa·s to 200 dPa·s, for example 60 dPa·s to 150 dPa·s, when the solution temperature is, for example, 70°C to 85°C.

[0038] [Formation of a layer of body fluid] Next, a layer of the mash liquor is formed. The layer of the mash liquor can be formed by any means, for example, simply pouring the mash liquor into a container. For example, as shown in FIG. 2(A), layer 1 of the mash liquor can be formed by pouring the mash liquor into a mold 100. As described above, the viscosity of the mash liquor changes depending on the temperature after heating. Therefore, if the viscosity of the mash liquor is such that it can be poured into a container, layer 1 of the mash liquor can be easily formed. Layer 1 of the mash liquor can also be formed by heating solidified mash liquor again in the container.

[0039] [Preparation of myocardial fluid] Separately from the body solution, the muscle solution is prepared. The muscle solution can be prepared by mixing titanium dioxide and / or calcium carbonate with a second thickening agent, for example, by mixing these with water.

[0040] The amount of titanium dioxide and / or calcium carbonate in the muscle fluid can be 0.2 parts by mass or more and 5 parts by mass or less, and preferably 0.2 parts by mass or more and 1 part by mass or less, per 100 parts by mass of the muscle fluid.

[0041] As the second thickening agent, those listed as examples of the first thickening agent can be used. However, the second thickening agent is adjusted so that the viscosity of the body solution and the muscle fluid are different. For example, the amount of the second thickening agent is preferably 0.05 parts by mass or more and 1 part by mass or less, and more preferably 0.1 parts by mass or more and 0.5 parts by mass or less, per 100 parts by mass of muscle fluid. Since the viscosity of the body solution and the muscle solution are different, the body solution and the muscle solution are not mixed when the muscle solution is inserted into the slit in the body solution.

[0042] The muscle fluid may also contain food ingredients and may contain additional optional ingredients such as ethanol.

[0043] In addition, when preparing the muscle liquid, each component can be mixed at any temperature. However, if the materials are simply mixed in water, the materials will not be sufficiently dissolved and lumps will form. In order to prevent the formation of lumps in the materials, the mixing temperature can be set to 1°C or higher and 30°C or lower. Alternatively, in order to prevent the formation of lumps in the materials, the mixed liquid may be produced while stirring the raw materials in water using a high-speed stirrer. In addition, when preparing the muscle liquid, it is preferable to heat the mixture after mixing. It is preferable to heat the mixture to a temperature at which the mixed muscle liquid components dissolve, for example, a temperature of 85°C or higher and 100°C or lower. By heating the muscle liquid, the color of the seafood product to be imitated can be reproduced more closely. It is preferable to heat and mix the mixture. The temperature for heating and mixing is preferably 60°C or higher, and more preferably 75°C or higher and 100°C or lower.

[0044] The muscle liquid is adjusted to have a different viscosity from the body liquid. The body liquid and the muscle liquid are solutions with different viscosities by appropriately adjusting the components of the first thickener and the second thickener. The viscosity of the muscle liquid is lower than that of the body liquid. The muscle liquid is blended so that it does not mix with the body liquid. Therefore, when an incision is made in the layer of the body liquid and the muscle liquid is poured between the body liquid, the muscle liquid is blended so that it does not mix with the body liquid and becomes a muscle layer. On the other hand, in the manufacturing method of the seafood imitation food of the present invention, the lower the viscosity of the muscle liquid, the easier it is for the muscle liquid to penetrate into the body liquid. Therefore, it is preferable that the viscosity of the muscle liquid is low enough to penetrate between the body liquid without mixing with the body liquid, and to easily penetrate between the body liquid.

[0045] After heating, the muscle fluid has a viscosity that gives it fluidity. The viscosity of the muscle fluid changes depending on the temperature. The higher the temperature, the lower the viscosity of the muscle fluid, because the components are dissolved by heating. The viscosity of the muscle fluid can be 0.01 dPa·s to 10 dPa·s, for example 0.1 dPa·s to 0.6 dPa·s, when the solution temperature is, for example, 60°C to 100°C. The viscosity of the muscle fluid can be 0.01 dPa·s to 10 dPa·s, for example 0.1 dPa·s to 0.6 dPa·s, when the solution temperature is, for example, 70°C to 85°C.

[0046] [Formation of myocardial fluid layer] Next, as shown in Fig. 2(B), a layer of muscle fluid 2 is formed on top of the layer of muscle fluid 1. Since the viscosities of muscle fluid 1 and muscle fluid 2 are different, the layer of muscle fluid 1 and the layer of muscle fluid 2 do not mix with each other.

[0047] The layer of muscle fluid 1 can have any thickness. For example, the layer of muscle fluid 2 can be 0.5 mm or more and 30 mm or less in thickness. The thicker the layer of muscle fluid 2, the greater the amount of muscle in the imitation food, and the thinner the layer of muscle fluid 2, the less the amount of muscle in the imitation food.

[0048] When forming a layer of muscle fluid 2 on the layer of muscle fluid 1, the temperatures of both muscle fluid 1 and muscle fluid 2 are adjusted so that they have a viscosity that allows the muscle fluid to enter between the muscle fluids. The temperatures of muscle fluid 1 and muscle fluid 2 can be, for example, 60°C or higher and 100°C or lower, for example, 65°C or higher and 90°C or lower, for example, 70°C or higher and 85°C or lower. In addition, it is preferable that the temperatures of muscle fluid 1 and muscle fluid 2 do not fall below the above-mentioned temperatures after heating when adjusting each solution, that is, they have a temperature of 60°C or higher, for example, 65°C or higher, for example, 75°C or higher, before forming a layer of muscle fluid 2 on the layer of muscle fluid 1. Once the temperature of muscle fluid 1 and muscle fluid 2 drops, the fluidity decreases, and they need to be heated again.

[0049] [Make a cut] Next, as shown in FIG. 2(C), a blade 3 is inserted from above the layer of myocardial fluid 2, and an incision (4 in FIG. 2(D)) is made by the blade 3 through the layer of myocardial fluid 2 into the layer of myocardial fluid 1.

[0050] The shape of the blade 3 can be appropriately selected according to the shape of the muscle to be formed in the imitation food. The thickness of the blade 3 can be selected according to the thickness of the muscle. The blade 3 can be, for example, a blade having a thickness of 0.1 mm to 10 mm, for example, 1 mm to 5 mm, for example, a stainless steel plate. Also, by arranging a plurality of blades 3 as shown in FIG. 2, it is possible to make cuts in the muscle liquid at once and introduce the muscle liquid.

[0051] [Inject muscle fluid into the incision] Next, the blade 3 is pulled out from the layer of the body fluid 1 in the direction of the white arrow in FIG. 2(D). Because the body fluid 1 and the muscle fluid 2 have different viscosities, when the blade 3 is pulled out, the body fluid 1 and the muscle fluid 2 do not mix, and the muscle fluid 2 enters the cut 4 provided in the layer of the body fluid 1, as shown in FIG. 2(E). At this time, the viscosity of the body fluid 1 and the muscle fluid 2 is such that the muscle fluid can flow into the body fluid. For example, in the case of the body fluid and the muscle fluid shown in the following example, if the temperature is 70° C. or higher, for example 80° C. or higher, the viscosity of the body fluid 1 and the muscle fluid 2 is such that the muscle fluid can flow into the body fluid.

[0052] Although a plurality of incisions 4 are formed simultaneously in FIG. 2, the incisions 4 may be formed one by one, or the muscle fluid 2 may be poured into each of the incisions 4 formed one by one.

[0053] <Solidification> Next, solidify the muscle fluid 1 and the muscle fluid 2. In this specification, solidifying includes solidifying the muscle fluid, which is a solution, into a state that is not a solution and does not have fluidity, and includes forming a gel that has solidified into a jelly-like state, for example.

[0054] Solidification can be achieved by solidifying the body fluid 1 and the muscle fluid 2 by a method appropriate to the components of the body fluid 1 and the muscle fluid 2, for example by increasing the viscosity of the body fluid 1 and the muscle fluid 2 and eliminating their fluidity.

[0055] The body fluid 1 and the muscle fluid 2 can be solidified, for example, by cooling. The body fluid 1 and the muscle fluid 2 can be solidified, for example, by cooling the body fluid 1 and the muscle fluid 2 to 20°C or less using a rapid cooling device such as a blast chiller with air blast. The body fluid 1 and the muscle fluid 2 can also be solidified by rapidly cooling to 0°C to 4°C. However, in order to increase safety, quality, and efficiency during cooling, it is preferable to solidify by rapid cooling. Alternatively, for example, when glucomannan is used as dietary fiber, the body fluid 1 and the muscle fluid 2 can be solidified (coagulated) by adding edible calcium hydroxide, called lye, to the body fluid 1 and mixing it.

[0056] After solidifying the flesh liquid 1 and the muscle liquid 2, the layer of muscle liquid 2 on top of the solidified flesh liquid 1 may be scraped off, leaving only the muscle liquid 2 embedded in the flesh liquid 1, as shown in FIG. 2(F). By scraping off the layer of muscle liquid 2 as shown in FIG. 2(F), a seafood imitation food 10 can be obtained in which veins are formed only between the flesh, as shown in FIG. 3. The seafood imitation food 10 is formed by the flesh 11 and the veins 12 formed therein being in close contact with each other and being integrated together. Such seafood imitation food 10 has an appearance in which the veins 12 are embedded in the flesh 11, just like real seafood. Furthermore, since the flesh 11 and the veins 12 are in close contact with each other, the flesh 11 and the veins 12 do not come apart, and an imitation food with excellent texture and appearance can be produced.

[0057] <Freeze> When tapioca powder is contained in the batter solution 1, it is preferable to freeze the imitation seafood food as shown in FIG. 4. Next, the solidified body is frozen. The freezing temperature is not particularly limited, but it can be performed at 0°C or below, and it can be cooled to a temperature of -18°C or below, for example, -20°C to -40°C. The freezing method is not particularly limited, but quick freezing is preferable. Freezing can be performed by using a blast chiller using air blast or by using brine. The cooling and freezing steps may be performed by continuous cooling, or it may be directly frozen to 0°C or below.

[0058] The present inventors have found that by freezing the solid obtained by solidifying the above-mentioned fish meat liquid containing tapioca, the solid can be given a turbidity like that of a seafood product. In addition, freezing makes it easier to cut the imitation food. If the solid is not given a turbidity like the seafood imitation food of the present invention, the imitation food will be too transparent and will have a jelly-like texture that does not look like a seafood product.

[0059] The solidified product before freezing has a texture that is not cloudy or has only a little cloudiness. Therefore, the cloudiness of the flesh of seafood products is not fully reproduced. On the other hand, after freezing, the imitation seafood products show the cloudiness that is characteristic of seafood products.

[0060] In other words, the imitation seafood food of the present invention can reproduce the cloudiness of seafood meat. Furthermore, it can also reproduce the texture of seafood meat. Furthermore, by mixing a coloring agent other than tapioca, such as lycopene pigment or paprika pigment, and heating the meat liquid, it is possible to reproduce the red meat of tuna or salmon. Various substances may be added to the meat liquid, and ingredients that enhance the flavor can be added.

[0061] The imitation seafood food may be produced by thawing after freezing, or the frozen product may be a finished product without thawing. EXAMPLES

[0062] They manufactured imitation seafood foods that resembled tuna. [Preparation of the body solution] First, to manufacture a tuna imitation seafood food, the raw materials shown in Table 1 were prepared. In Table 1, the blend amounts are shown in kg, and the blend ratios in the final fish meat solution are shown as weight / %.

[0063] [Table 1]

[0064] The ingredients shown in Raw Material 1 were placed in a pot with external dimensions: width 1850 mm x depth 1090 mm x height 1160 mm, inner pot inner diameter: 1000 mm, inner pot depth: 560 mm, and full water capacity: approximately 380 liters, and mixed with a stirrer. The temperature was controlled at 30°C or less.

[0065] Meanwhile, a solution of cornstarch and tapioca starch shown in raw material 2 was prepared. 2.4 kg of cornstarch (2.78 wt / % in the final batter solution) and 1.6 kg of tapioca starch (1.85 wt / % in the final batter solution) were added to 4 kg of water (4.63 wt / % in the final batter solution) and mixed. The mixing was carried out at 30°C or lower. The prepared cornstarch and tapioca solution of raw material 2 was added to the above-mentioned raw material 1 mixture.

[0066] The vegetable soup made from ingredient 3 has the composition shown in Table 2.

[0067] [Table 2]

[0068] Heating of the contents of the kettle was then commenced. During heating, 5 kg of vegetable soup (5.79% by weight of the final meat solution) was added to the kettle containing Ingredient 1 and Ingredient 2.

[0069] When the temperature of the contents of the kettle exceeded 85° C., the heating was stopped. This resulted in the production of the pulp solution.

[0070] The viscosity of the solution at this time was measured. The viscosity was measured using a Rion Co., Ltd. Viscometer VT-06 according to the procedure. When the temperature of the solution was 80℃ to 85℃, the viscosity was 70 dPa·s to 80 dPa·s.

[0071] In addition, the Brix value of the meat solution was measured as the viscosity of the solution using a Brix meter when the core temperature was 85°C. The concentration of the meat solution was 15% to 18%. In this specification, the "Brix value" is a physical quantity used as sugar content to measure the sugar content. When 100g of an aqueous solution containing only 1g of sucrose as a solute is measured using a Brix refractometer, the Brix value is 1%. For example, a solution in which 10g of sucrose is dissolved in 100g of solution (water is 90g) has a Brix value of 10%. The meat solution can have a Brix value of 1% to 40%, 12% to 20%, or 15% to 18%, for example.

[0072] [Preparation of myocardial fluid] The following raw materials were prepared:

[0073] [Table 3]

[0074] These ingredients were mixed to prepare muscle fluid.

[0075] The viscosity of the muscle solution at this time was measured. The viscosity was measured using a Rion Co., Ltd. Viscometer VT-06 according to the procedure. When the temperature of the muscle solution was 80℃ to 85℃, the viscosity was 0.3 dPa·s to 0.6 dPa·s, which is a low-viscosity solution close to that of water.

[0076] [Formation of layers of body fluids and layers of muscle fluid] A layer of 80℃ to 85℃ of muscular fluid was poured into a mold. Next, a layer of muscular fluid was formed by pouring a layer of 80℃ to 85℃ of muscular fluid on top of the layer of muscular fluid. The thickness of the layer of muscular fluid 2 was set to 30 mm relative to the thickness of the layer of 1.

[0077] [Cut formation] Next, a 5mm stainless steel blade was inserted from above the layer of muscle fluid, and the blade passed through the layer of muscle fluid and made an incision in the layer of body fluid.Then, the blade was removed upwards, allowing the muscle fluid to penetrate into the incision in the layer of body fluid.

[0078] [Solidification] In this state, the body fluid and muscle fluid were solidified. The container was cooled to 0°C to 4°C with a blast chiller, solidifying the body fluid and muscle fluid and obtaining a solidified body.

[0079] [frozen] The solidified body was rapidly cooled in a freezer at -40°C to freeze the solidified body of the body fluid and the muscle fluid. From the frozen solidified body, the layer of muscle fluid that was not mixed with the body fluid layer was scraped off.

[0080] [Unzip] The frozen solid was placed in a bag and the bag was sealed. The bag was placed in hot water at 50° C. or less and left for 0.5 hours. In this way, the imitation seafood food of Example 1 was obtained.

[0081] [evaluation] A sensory test was carried out on the imitation seafood food produced by the above method. The evaluation was carried out according to the following procedure.

[0082] 1. Conducting the sensory testing procedure The panelists who carried out the sensory test were people who had experience in the product inspection process and could judge the color, rotten odor, and off-odor of tuna. In addition, the panelists who carried out the sensory test were selected from those who had passed the taste discrimination test.

[0083] The panelists were five people selected from the bacterial test personnel and the panelists of tuna processed products and seafood imitation foods. The sensory test was carried out under the following conditions. Sensory testing is done when panelists are neither hungry nor full. Test samples should be tested at the temperature at which they would normally be consumed. - Prepare a test sample in an amount that allows the panelists to feel the chewiness and texture of the sample on their tongue. The panelists who performed the sensory test judged the color, smell, and taste and recorded the results. The panelists who performed the sensory test judged the food including texture and syneresis and recorded the results. - Before testing and while eating each product, drink water to minimize the impact on the next product test.

[0084] The sensory test was conducted to judge the acceptability of the following four items: color, smell, texture, and syneresis. The judgment criteria for each item are as follows: Color: Compared to tuna, salmon, and squid, it has a similar or close color. Odor: No putrid or unpleasant odors Texture: The texture is similar to that of tuna, salmon, or squid, and has the characteristic taste of imitation foods. Syneresis: No obvious syneresis occurs upon thawing.

[0085] 2. Sensory test results Ten batches of imitation seafood were produced and tested using the above procedure. All five panelists judged all ten batches to be acceptable in terms of color, odor, texture and syneresis.

[0086] In addition, the fishery imitation food produced by the above method had a muscle and flesh that were integrated and did not separate at the muscle. The fishery imitation food produced by the above method had a texture similar to sashimi. The fishery imitation food produced by the above method had an appearance similar to red tuna meat due to the white color of tapioca starch and the red color of lycopene. EXAMPLES

[0087] They manufactured imitation seafood foods that resembled salmon. [Preparation of the body solution] First, to manufacture a salmon imitation seafood food, the raw materials shown in Table 2 were prepared. In Table 2, the blend amounts are shown in kg, and the blend ratios in the final fish meat solution are shown as weight / %.

[0088] [Table 4]

[0089] The ingredients shown in Raw Material 1 were placed in a kettle with the same outer dimensions as in Example 1 (width 1850 mm × depth 1090 mm × height 1160 mm, inner diameter of inner kettle 1000 mm, inner depth of inner kettle 560 mm, and full water capacity of about 380 liters) and mixed with a stirrer. The temperature was controlled at 30°C or less.

[0090] Meanwhile, a solution of cornstarch and tapioca starch shown in raw material 2 was prepared. 2.4 kg of cornstarch (2.78 wt / % in the final batter solution) and 1.6 kg of tapioca starch (1.85 wt / % in the final batter solution) were added to 4 kg of water (4.63 wt / % in the final batter solution) and mixed. The mixing was carried out at 30°C or lower. The prepared cornstarch and tapioca solution of raw material 2 was added to the above-mentioned raw material 1 mixture.

[0091] The vegetable soup made from ingredient 3 has the composition shown in Table 2 above.

[0092] Heating of the contents of the kettle was then commenced as in Example 1. During heating, 5 kg of vegetable soup (5.79 wt / % of the final meat solution) was added to the kettle containing Raw Material 1 and Raw Material 2.

[0093] When the temperature of the contents of the kettle exceeded 85° C., the heating was stopped. This resulted in the production of the pulp solution.

[0094] The viscosity of the solution at this time was measured. The viscosity was measured using a Rion Co., Ltd. Viscometer VT-06 according to the procedure. When the temperature of the solution was 80℃ to 85℃, the viscosity was 70 dPa·s to 80 dPa·s.

[0095] In addition, the Brix value of the meat solution was measured as the viscosity of the solution using a Brix meter when the core temperature was 85° C. The concentration of the meat solution was 15% to 18%.

[0096] [Preparation of myocardial fluid] The muscle fluid was prepared in the same manner as in Example 1.

[0097] [Formation of layers of body fluids and layers of muscle fluid] A layer of body fluid and a layer of muscle fluid were formed in the same manner as in Example 1.

[0098] [Cut formation] The incisions were made in the same manner as in Example 1, and muscle fluid penetrated into the incisions in the layer of muscle fluid.

[0099] [Solidification] A solidified body was obtained in the same manner as in Example 1.

[0100] [frozen] The solidified body was frozen in the same manner as in Example 1, and the layer of muscle fluid that had not penetrated into the layer of muscle fluid was scraped off from the frozen solidified body.

[0101] [evaluation] The imitation seafood food of Example 2 was evaluated in the same manner as in Example 1.

[0102] Sensory test results Ten batches of imitation seafood were produced and tested using the above procedure. All five panelists judged all ten batches to be acceptable in terms of color, odor, texture and syneresis.

[0103] In addition, the fishery imitation food produced by the above method had a muscle and flesh that were integrated and did not separate at the muscle. The fishery imitation food produced by the above method had a texture similar to sashimi. The fishery imitation food produced by the above method had a white color from tapioca starch and a red color from paprika and lycopene, giving it an appearance similar to red salmon meat. [Industrial Applicability]

[0104] The manufacturing method of the present invention for producing imitation seafood foods as described above involves forming a layer of muscle fluid, which has a different viscosity from the muscle fluid, on top of a layer of flesh fluid, and using a blade to pass through this layer of muscle fluid to make an incision in the layer of flesh fluid, and then removing the blade to allow the muscle fluid to enter the incision, thereby producing imitation seafood foods with veins that look just like real seafood foods.

[0105] In addition, by adding tapioca powder, paprika pigment, lycopene pigment, etc. to the meat liquid, solidifying it, and freezing it, the color, opacity, and texture of red meat of tuna and salmon can be reproduced. [Explanation of symbols]
