Description

Technical Field

[0001] This invention relates to a natural, calcium- and collagen-rich slurry and its applications. Background Technology

[0002] Byproducts from seafood processing and low-value seafood raw materials caught can be processed into seafood seasonings, fish rolls, fish balls, shrimp balls, and other products using advanced processing techniques. For example, small fish and shrimp contain collagen and calcium, which, if utilized properly, can provide excellent nutritional value for humans.

[0003] Chinese invention patent application CN107296254A, entitled "A Seafood Seasoning Piece and Its Preparation Method," discloses a seafood seasoning piece comprising the following ingredients in parts by weight: 55-65 parts small miscellaneous fish, 30-45 parts fresh shrimp heads, 10-20 parts squid meat, 20-35 parts kelp powder, 3-6 parts disodium succinate, 2-4 parts monosodium glutamate, 3-12 parts filler, 1-3 parts salt, 0.25-0.5 parts monoglyceride fatty acid ester, 0.1-0.15 parts sucrose fatty acid ester, 0.03-0.08 parts acidity regulator, 0.005-0.01 parts antioxidant, and 1-3 parts flavoring agent. In its production, small miscellaneous fish, fresh shrimp heads, and squid meat are crushed and then pressure-cooked. The remaining ingredients are then added, stirred, crushed, ground, homogenized and emulsified, spray-dried, sieved, blended, granulated, dried, and pressed into tablets to produce seafood seasoning tablets.

[0004] For example, Chinese invention patent application CN107467342A, entitled "A Processing Method for a Small Fish Protein Powder Product," discloses a processing method for a small fish protein powder product, including the following steps: 1) Pretreatment: After removing the internal organs, scales, and gills of the small fish, mince them into fish paste, add water, and grind into a fish homogenate; 2) Degreasing: Add phospholipase A1 and phospholipase A2 to the fish homogenate, use infrared temperature control for enzymatic hydrolysis, inactivate the enzymes after hydrolysis, add organic solvent, stir, filter to collect the precipitate, and... 3) Wash with ethanol; 4) Enzymatic hydrolysis: Add water and compound protease to the precipitate, use infrared temperature control for enzymatic hydrolysis, inactivate the enzyme after enzymatic hydrolysis, adjust the pH and then add tissue protease for enzymatic hydrolysis, use infrared temperature control for enzyme inactivation, filter and collect the filtrate; 5) Deodorization: Add deodorizing solution to the filtrate, stir evenly and let stand; 6) Ultrafiltration: Ultrafilter the deodorized filtrate and collect the filtrate; 7) Desalination: Desalinate the filtrate through ion exchange resin to obtain desalted liquid; 8) Spray drying: Spray dry the desalted liquid to obtain small miscellaneous fish protein powder product.

[0005] While processing seafood into granules or powder can extend the shelf life of the product, the process is quite complicated. In addition, prolonged high-pressure cooking or high-temperature treatment can affect the taste of seafood products.

[0006] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0007] The purpose of this invention is to provide a natural, calcium- and collagen-rich paste that can better preserve the taste of seafood products and extend their shelf life. Another purpose of this invention is to propose the application of this paste, which can better preserve the flavor of seafood products.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A natural, calcium- and collagen-rich paste is prepared using the following steps:

[0010] Step A: Remove the heads and internal organs of the small fish, and soak the processed small fish and shrimp in a 25%-35% salt solution for 0.5 to 1.5 hours.

[0011] Step B: The small fish and shrimp processed in Step A are scooped up, washed, and then ground in a grinding and separating machine to form a slurry;

[0012] C. Step C: Package the slurry obtained in step B.

[0013] In a preferred embodiment of the present invention, the grinding and separating machine includes a frame, an outer cylinder fixed on the frame, an inner cylinder disposed inside the outer cylinder, and a drive mechanism for driving the inner cylinder to rotate. The inner cylinder includes a filter cylinder and a grinding cylinder disposed inside the filter cylinder. The filter cylinder is provided with mesh holes with a mesh diameter of 0.03 to 0.06 mm. The outer cylinder is provided with a first feed port that can be opened and closed and a first baffle for opening and closing the first feed port. The filter cylinder is provided with a second feed port that can be opened and closed and a second baffle for opening and closing the second feed port. The grinding cylinder is provided with a third feed port and a third baffle for opening and closing the third feed port. A discharge valve for discharging the slurry is also provided at the lower part of the outer cylinder.

[0014] In a preferred embodiment of the present invention, the third baffle is detachably sealed to the third feed port by means of a disc bolt.

[0015] In a preferred embodiment of the present invention, the axis of the inner cylinder is arranged in a horizontal direction, one end of the filter cylinder is rotatably disposed on the inner wall of the outer cylinder via a first rotating shaft, and the other end of the filter cylinder is rotatably disposed on the outer cylinder via a second rotating shaft and extends out of the outer cylinder.

[0016] In a preferred embodiment of the present invention, the two ends of the grinding cylinder are fixedly connected to the filter cylinder via connecting shafts.

[0017] In a preferred embodiment of the present invention, the driving mechanism is a motor, and the output shaft of the motor is connected to the second rotating shaft via a transmission connection.

[0018] In a preferred embodiment of the present invention, the outer cylinder is provided with a cleaning port, which is provided corresponding to the inner cylinder. The cleaning port extends from the outer wall of the outer cylinder to the inner wall, and a water pipe is connected to the cleaning port.

[0019] As a preferred embodiment of the present invention, in step B, water is also added to the grinding cylinder, and the amount of water added is 5%-15% of the total weight of the small fish and the small shrimp.

[0020] This invention also proposes the application of a natural, calcium- and collagen-rich paste, which can be used to make fish rolls, fish balls, fish cakes, fish flakes, shrimp flakes, shrimp balls, or shrimp rolls.

[0021] The present invention also proposes the application of a natural, calcium- and collagen-rich slurry. After the slurry is cooked, it is used to make tofu. The slurry accounts for 20-60% of the total mass of the tofu.

[0022] By adopting the technical solution of this invention, small fish and shrimp can be sterilized by soaking in salt solution. Compared with traditional high-temperature sterilization, this invention can better preserve the original characteristics of collagen and calcium in small fish and shrimp. The small fish and shrimp are ground and separated by a grinding and separating machine and then packaged. The process is simple and can preserve the taste of small fish and shrimp to the greatest extent. This invention proposes a grinding and separating machine capable of producing this slurry. Its inner cylinder employs a filter cylinder surrounding a grinding cylinder. After grinding, the third feed port is opened, and a drive mechanism rotates both the filter cylinder and the grinding cylinder. The ground slurry is thrown through the third feed port into the filter cylinder, and then through the filter cylinder's mesh into the outer cylinder. Finally, the slurry is discharged through the outer cylinder's discharge valve for packaging. Because the slurry of this invention is viscous, its penetration efficiency is low when passing through ordinary screens, especially small-aperture screens. Throwing the slurry from the grinding cylinder to the filter cylinder, and then having the filter cylinder rotate to move the slurry into the outer cylinder, improves the filtration efficiency. Integrating the grinding cylinder and filter cylinder within the outer cylinder reduces raw material transfer and increases processing efficiency. This invention also proposes applications for this slurry, such as in the production of fish rolls and tofu. Attached Figure Description

[0032] To further explain the technical solution of the present invention, the following detailed description is provided in conjunction with embodiments.

[0033] Reference Figure 1 A natural, calcium- and collagen-rich paste is prepared using the following steps:

[0034] Step A: Remove the heads and internal organs of the small fish. The heads of the small shrimp do not need to be removed. The small fish and shrimp used in this application can be existing small fish and shrimp. Preferably, wild small fish or shrimp are selected. Soak the processed small fish and shrimp in a 25%-35% salt (commonly available edible salt) solution for 0.5 to 1.5 hours.

[0035] Step B: The small fish and shrimp processed in step A are scooped up and washed. In this embodiment, they are washed 2 to 3 times with clean water and then put into a grinding separator for grinding to form a slurry.

[0036] C. Step C: Package the slurry obtained in step B, either by bagging or filling.

[0037] In a preferred embodiment of the present invention, the grinding and separating machine includes a frame 10, an outer cylinder 20 fixed on the frame 10, an inner cylinder disposed within the outer cylinder 20, and a drive mechanism for driving the inner cylinder to rotate. The outer cylinder 20 and the inner cylinder are coaxially arranged, and their axes are arranged horizontally. The inner cylinder includes a filter cylinder 30 and a grinding cylinder 40 disposed within the filter cylinder 30. The filter cylinder 30 and the grinding cylinder 40 are coaxially arranged, with the filter cylinder 30 sleeved over the grinding cylinder 40. The filter cylinder 30 is provided with mesh holes 31, specifically, the mesh holes 31 are evenly distributed on the circumferential surface of the filter cylinder 30, and the aperture of the mesh holes 31 is between 0.03 and 0.06 mm. In this invention, the grinding cylinder 40 can be used to grind small fish and shrimp. For example, blades can be provided on the inner wall of the grinding cylinder 40, or abrasive can be added separately. Through the high-speed rotation of the grinding cylinder 40, the small fish and shrimp come into contact with the blades or abrasive, achieving grinding. The grinding time of this invention can be, for example, 10 to 20 minutes.

[0038] The outer cylinder 20 is provided with a first feed port that can be opened and closed and a first baffle for opening and closing the first feed port. The filter cylinder 30 is provided with a second feed port that can be opened and closed and a second baffle for opening and closing the second feed port. The grinding cylinder 40 is provided with a third feed port 41 and a third baffle 42 for opening and closing the third feed port 41. A discharge valve 21 for discharging the slurry is also provided at the lower part of the outer cylinder 20. In this invention, the cooperation structure of the third feed port 41 and the third baffle 42 is described. For example, the third feed port 41 is rectangular, and four screw holes are opened at the four corners of the third feed port 41. Disc bolts 43 are installed in the screw holes. After the third baffle 42 is placed in the third feed port 41, the third baffle 42 is pressed onto the grinding cylinder 40 by rotating the disc bolts 43. In order to make the third baffle 42 more stable, a corresponding groove can be opened on the grinding cylinder 40, and the third baffle 42 can be positioned in the groove and further locked by the disc bolts. To ensure sealing performance, a sealing gasket is provided between the third baffle 42 and the third feed port 41. When it is necessary to open the third feed port 41, the disc bolt 43 is loosened and the third baffle 42 is removed. In this invention, the mating structure between the first feed port and the first baffle, and the mating structure between the second feed port and the second baffle, can adopt the same mating structure as that between the third feed port 41 and the third baffle 42. In this invention, both ends of the filter cylinder 30 along the axial direction, both ends of the grinding cylinder 40 along the axial direction, and both ends of the outer cylinder 20 along the axial direction can all adopt a closed structure, and the first feed port, the second feed port, and the third feed port 41 are arranged on the circumferential surface of the cylinder.

[0039] In a preferred embodiment of the present invention, the axis of the inner cylinder is arranged horizontally, one end of the filter cylinder 30 is rotatably mounted on the inner wall of the outer cylinder 20 via a first rotating shaft 32, and the other end of the filter cylinder 30 is rotatably mounted on the outer cylinder 20 and extends out of the outer cylinder 20 via a second rotating shaft 33. In a preferred embodiment of the present invention, the driving mechanism is a motor 50, and the output shaft of the motor 50 is connected to the second rotating shaft 33. The motor 50 is a motor capable of both forward and reverse rotation; during grinding or unloading, the alternating forward and reverse rotation of the motor 50 allows for better grinding or slurry ejection. In a preferred embodiment of the present invention, both ends of the grinding cylinder 40 are fixedly connected to the filter cylinder 30 via connecting shafts 44.

[0040] In a preferred embodiment of the present invention, the outer cylinder 20 is provided with a cleaning port 22, which is provided corresponding to the inner cylinder. The cleaning port 22 extends from the outer wall of the outer cylinder 20 to the inner wall. A water pipe is connected to the cleaning port 22, and water is sprayed onto the filter cylinder 30 through the water pipe. With the rotation of the filter cylinder 30, the filter cylinder 30 can be cleaned.

[0041] In a preferred embodiment of the present invention, in step B, water is added to the grinding cylinder 40. The amount of water added is 5%-15% of the total weight of the small fish and the small shrimp. The addition of water can make the small fish and shrimp flow more easily and improve the grinding efficiency.

[0042] This invention also proposes the application of a natural, calcium- and collagen-rich slurry, which can be used to make fish rolls, fish balls, fish cakes, fish floss, shrimp floss, shrimp balls, or shrimp rolls. For example, taking fish rolls as an example, the slurry of this application is mixed with starch and kneaded into a cylindrical shape. The amount of starch added is 10% to 20% of the slurry's weight, followed by conventional steaming. This invention also proposes a novel method for making fish rolls, in which the slurry of this invention is mixed with mung bean starch (or pea starch), with the mung bean starch (or pea starch) added to 5% to 15% of the slurry's weight, followed by conventional steaming. This invention uses mung bean starch or pea starch instead of traditional sweet potato starch; fish rolls with added mung bean starch have antibacterial and lipid-lowering effects.

[0043] This invention also proposes the application of a natural, calcium- and collagen-rich slurry. After cooking, the slurry is used in tofu production, and the slurry accounts for 20-60% of the total tofu mass. Specifically, in existing tofu-making processes, after adding gypsum and draining most of the water, 20-60% of the slurry is added, mixed evenly, and then pressed to form fish paste tofu.

[0044] The paste of this invention can also be applied in other fields: for example, it can be added to the production process of gelatin jelly or agar jelly for flavoring, forming seafood jelly. It can also be added to the traditional preparation of white rice cake snacks for flavoring, thus making seafood white rice cake. Furthermore, it can be added to the traditional preparation of radish cake for flavoring, making seafood radish cake. Finally, it can be added to the production process of fish-flavored biscuits, shrimp-flavored biscuits, or potato chips for flavoring, forming biscuits or potato chips with specific flavors.

[0045] The product form of the present invention is not limited to the embodiments described in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of the present invention.
