Abstract
Description
Cultured cell-based caviar and its production method
[0001] The present invention relates to caviar based on cultured cells including alginate, seaweed powder and cultured cells, and a method for producing the same.
[0002] The sturgeon is the largest freshwater fish, boneless and composed of over 70% cartilage. Sturgeon do not spawn annually, but only a few times in their lifetime. Compared to other fish, they produce a large number of eggs. These salt-cured sturgeon roe is called caviar, and salted caviar is renowned as one of the world's three greatest delicacies. Caviar is made by carefully straining the roe from freshly caught sharks through a fine sieve to remove any remaining tissue and fat. The roe is then seasoned with 4-6% salt.
[0003] Caviar is rich in nutrients such as protein, fat, sugar, vitamins, and minerals, and is reported to be a complete nutritional food with low calories and high protein content. The protein contained in caviar is a stable balance of essential amino acids such as leucine, isoleucine, lysine, and arginine, as well as amino acids such as alanine, serine, glutamic acid, and aspartic acid, which function as essential elements for cellular metabolism. Similar to the protein structure of human skin, caviar is absorbed into the skin faster than other ingredients and is excellent for continuously providing nutrients to the skin even after absorption. Russians use caviar for the recovery of surgical patients due to its high protein content and ease of digestion, and it is also used to prevent and treat diseases such as rickets in children.
[0004] Meanwhile, overfishing for sturgeon roe has led to a severe decline in sturgeon populations, and Russia's ban on sturgeon fishing has made caviar difficult to obtain. While sturgeon farming has increased, it still fails to meet the demand for caviar, and sturgeon conservation remains a concern.

[0021] Hereinafter, the present invention will be described in detail.
[0022]
[0023] According to one embodiment of the present invention, cultured cell-based caviar comprises alginate, seaweed powder, and cultured cells. Each component is described in detail below.
[0024] The above cultured cell-based caviar has similar characteristics to wild caviar in terms of texture, flavor, strength, etc., and has a spherical shape, so it can be manufactured in a shape similar to that of wild caviar.
[0025] The above alginate is a natural polysaccharide and is the main component of brown algae such as kelp and wakame. Alginate has excellent biocompatibility, low toxicity, and is relatively inexpensive. Alginate can form hydrogel beads by cross-linking with polyvalent cations. At this time, the polyvalent cation is calcium ion (Ca 2+ ), strontium ion (Sr 2+ ), barium ion (Ba 2+ ), copper ion (Cu 2+ ), iron ion (Fe 2+ ) and aluminum ions (Al 2+ ) may include at least one selected from the group consisting of. In particular, divalent cations can relatively easily form cross-links with alginate. Alginate forms a cross-link when it meets a polyvalent cation to form a hydrogel, which provides rigidity to the cultured cell-based caviar and provides a basis for maintaining its shape.
[0026] The above seaweed powder may include at least one selected from the group consisting of kelp powder, hijiki powder, laver powder, seaweed powder, and laver powder. The above seaweed powders may be combined and used so that the flavor of the cultured cell-based caviar is similar to the flavor of wild caviar. The kelp powder includes active ingredients such as laminarin, alginic acid, fucoidan, laminin, iodine, bromine, and sodium. The hijiki powder includes active ingredients such as alginic acid, potassium alginate, sodium alginate, calcium, potassium, iodine, phospholipid, and glutamic acid. The laver powder has a protein content that is about 30-40% higher than that of other seaweeds, and is composed of essential amino acids such as threonine, valine, leucine, isoleucine, lysine, methionine, and phenylalanine, and contains active ingredients such as riboflavin, niacin, vitamin C, glycine, and alanine. The above seaweed powder contains active ingredients such as vitamin A, carbohydrates, fat, fucoidan, carbohydrates, calcium, potassium, iron, iodine, and pigments. The above seaweed powder is rich in minerals and iron.
[0027] The above cultured cells can be cultured in a medium for culturing animal cells. The above cultured cells may refer to cultured cells cultured in a culture medium that is commonly applicable to crustaceans and in which the growth and proliferation of crustacean cells actively progresses.
[0028] The cultured cells may be based on one or more crustacean cells selected from the group consisting of shrimp, crab, and lobster. Preferably, the cultured cells may be protein cells derived from shrimp cells. The cultured cells have similar nutritional components and structure to shrimp, crab, or lobster cells, and have similar characteristics, and can maintain cell growth even after long-term storage.
[0029] The weight ratio of the alginate, seaweed powder, and cultured cells may be 0.8 to 2:0.5 to 5:5 to 15. Preferably, the weight ratio of the alginate, seaweed powder, and cultured cells may be 1:0.5 to 5:5 to 15.
[0030] The above alginate can play a role in maintaining the shape of the cultured cell-based caviar so that it can maintain a spherical shape for a long time after production, and it plays a role in controlling the strength so that it has properties similar to those of natural caviar.
[0031] The above seaweed powder can reproduce a scent similar to that of wild caviar and reproduces the unique flavor and taste of caviar. If the seaweed powder is included below the above numerical range, the caviar scent may not be reproduced, and cross-linking with alginate may not be sufficiently achieved, which may weaken the shape retention of the final product. If the seaweed powder is included above the above numerical range, the scent may become stronger, causing discomfort when consumed.
[0032] Preferably, the seaweed powder may be a mixed powder obtained by mixing seaweed powder, laver powder, and laver powder in a weight ratio of 0.5:0.5:0.1 to 0.2. The seaweed mixed powder combined in the above weight ratio can reproduce a flavor most similar to that of wild caviar.
[0033] If the cultured cells are included below the above numerical range, the nutritional content of the final cultured cell-based caviar may be insufficient, and it may be difficult to maintain a firm spherical shape. If the cultured cells are included above the above numerical range, the final cultured cell-based caviar may not be formed into a spherical shape but rather an elongated columnar shape, which may differ in shape from wild caviar.
[0034] The cultured cell-based caviar comprising the alginate, seaweed powder, and cultured cells may further comprise seasoning, cocoa powder, and lemon juice. The seasoning may include at least one selected from the group consisting of soy sauce and salt. The seasoning may be added to increase the salinity of the cultured cell-based caviar. The cocoa powder may be added to enable the cultured cell-based caviar to exhibit a color similar to that of wild caviar.
[0035] The cultured cell-based caviar including the alginate, seaweed powder, and cultured cells may further include soy sauce, salt, cocoa powder, and lemon juice, and the weight ratio of the alginate, seaweed powder, cultured cells, soy sauce, salt, cocoa powder, and lemon juice may be 0.8 to 2:0.5 to 5:5 to 15:5 to 15:5 to 15:1 to 5:0.1 to 1. Preferably, the numerical range may be 1:0.5 to 5:5 to 15:5 to 15:5 to 15:1 to 5:0.1 to 1. When the soy sauce is included in an amount less than the numerical range, the flavor of the caviar may be reduced, and when the soy sauce is included in an amount exceeding the numerical range, the flavor may become too strong. If the lemon juice is included in an amount below the above numerical range, the taste of the caviar may be reduced, and if it is included in an amount exceeding the above numerical range, the flavor may become too strong.
[0036] A method for producing cultured cell-based caviar according to one embodiment of the present invention comprises the steps of: preparing a mixed solution by mixing alginate, seaweed powder, and cultured cells in distilled water; moving the mixed solution to an injection port through a pump; preparing an injection product from the mixed solution moved to the injection port; injecting the injection product obtained from the mixed solution into a calcium chloride solution and then stirring to crosslink; washing the spherical injection product that has undergone the crosslinking step; and drying the washed spherical injection product and then mixing it with a xanthan gum solution.
[0037] The step of preparing a mixed solution by adding the alginate, seaweed powder, and cultured cells to distilled water and mixing them is to induce cross-linking between the alginate and polyvalent cations and to uniformly mix the seaweed powder and cultured cells. The step of preparing the mixed solution may first dissolve the alginate by stirring in distilled water at 65°C to 75°C for 1 hour, and then add the seaweed powder and cultured cells and stir for 30 to 40 minutes to prepare a mixed solution. In the step of preparing the mixed solution, at least one selected from the group consisting of soy sauce, salt, cocoa powder, and lemon juice may be further added to prepare the mixed solution.
[0038] The step of moving the above mixed solution through the pump to the injection port is to apply a constant pressure to the uniformly mixed solution so that the cultured cell-based caviar can be discharged in a constant shape. The constant shape may be a spherical shape.
[0039] The step of manufacturing an injection molded product from the mixed solution moved to the above injection port is to maintain the shape of the injection molded product uniform by adjusting the size of the injection port to 0.5 mm to 1.25 mm.
[0040] The step of injecting the injection molding obtained from the above mixed solution into a calcium chloride solution and then stirring and crosslinking is to manufacture the injection molding obtained from the above mixed solution into a spherical shape that can maintain its shape by adding the injection molding obtained from the above mixed solution to a calcium chloride solution in which calcium chloride is dissolved in distilled water and crosslinking the injection molding. The average diameter of the injection molding obtained from the above spherical mixed solution may be 2.46 mm to 3.43 mm.
[0041] The above calcium chloride solution may contain 95 to 99.2 parts by weight of distilled water based on 0.8 to 5 parts by weight of the calcium chloride. If the content of the calcium chloride is less than the above numerical range, the shape of the injection obtained from the mixed solution may not be maintained consistently for a long time and may not be easy to store, and if the content exceeds the above numerical range, it may be difficult to manufacture the injection into a spherical shape.
[0042] The step of washing the spherical injection molded product that has undergone the above cross-linking step is to remove impurities and remaining calcium chloride.
[0043] In the step of drying the washed spherical injection molded product and mixing it with a xanthan gum solution, the drying is performed to enhance the texture of the final product, cultured cell-based caviar, and to prevent water loss. In addition, in the step of drying the washed spherical injection molded product and mixing it with a xanthan gum solution, the xanthan gum solution is added to control the viscosity of the cultured cell-based caviar, prevent clumping, and prevent water loss.
[0044] In the step of preparing a mixed solution by mixing the alginate, seaweed powder, and cultured cells in distilled water, the mixed solution may include 0.5 to 10 parts by weight of the seaweed powder and 1 to 20 parts by weight of the cultured cells based on 0.8 to 2 parts by weight of the alginate. Preferably, 0.5 to 10 parts by weight of the seaweed powder and 1 to 20 parts by weight of the cultured cells may be included based on 1 part by weight of the alginate. Most preferably, 0.5 to 5 parts by weight of the seaweed powder and 5 to 15 parts by weight of the cultured cells may be included based on 1 part by weight of the alginate. If the content of the seaweed powder is less than the above numerical range, the caviar flavor may not be reproduced and cross-linking with the alginate may not be sufficiently achieved, thereby weakening the shape retention of the final product, cultured cell-based caviar. If the content of the seaweed powder exceeds the above numerical range, the flavor may be strong, causing discomfort when consumed. If the content of the cultured cells falls below the above numerical range, the nutritional composition of the final product, cultured cell-based caviar, may become unbalanced, and the spherical shape may not be maintained firmly. If the content of the cultured cells exceeds the above numerical range, the extruded product may not form a spherical shape but may instead form an elongated columnar shape, and the texture and mouthfeel may differ from those of wild caviar.
[0045] In the step of preparing a mixed solution by mixing the alginate, seaweed powder, and cultured cells in distilled water, the weight ratio of the alginate, seaweed powder, and cultured cells may be 0.8 to 2:0.5 to 5:5 to 15. Preferably, the weight ratio may be 1:0.5 to 5:5 to 15. If the seaweed powder is included in an amount less than the above numerical range, the caviar flavor may not be reproduced, and cross-linking with alginate may not be sufficiently achieved, thereby weakening the shape retention of the final product, cultured cell-based caviar. If the seaweed powder is included in an amount exceeding the above numerical range, the seaweed flavor may become strong, causing discomfort when consumed. If the cultured cells are included in an amount less than the above numerical range, an imbalance in the nutritional components of the final product, cultured cell-based caviar, may occur, and the spherical shape may not be maintained for a long time. If the cultured cells are included in excess of the above numerical range, the shape of the injection product is not formed into a spherical shape but rather into an elongated columnar shape, resulting in a shape different from that of natural caviar, and the texture and mouthfeel may be different when consumed.
[0046] In the step of moving the above-mentioned mixed solution to the injection port through the pump, the pump flow rate may be 0.1 to 5 ml / min. Preferably, the pump flow rate may be 0.1 to 4 ml / min. If the pump flow rate is below the above-mentioned numerical range, the shape of the injection product cannot be maintained constant, and if it exceeds the above-mentioned numerical range, it is not suitable for producing a spherical injection product. The pump may use a peristalic pump.
[0047] In the step of injecting the injection molding obtained from the above mixed solution into a calcium chloride solution and then stirring and crosslinking, the weight ratio of the injection molding obtained from the above mixed solution to the calcium chloride solution may be 1:0.1 to 1. Preferably, the weight ratio may be 1:0.5 to 0.9. If the calcium chloride solution is included in an amount less than the above numerical range, the shape retention of the injection molding may be weakened, and if it is included in an amount exceeding the above numerical range, the injection molding may not have a texture similar to that of wild caviar.
[0048] In the step of injecting the injection product obtained from the above mixed solution into a calcium chloride solution and then stirring and crosslinking, the calcium chloride solution may contain 95 to 99.2 parts by weight of distilled water based on 0.8 to 5 parts by weight of the calcium chloride. If the content of the calcium chloride is less than the above numerical range, the shape of the final product, cultured cell-based caviar, may not be maintained consistently for a long time and may not be easy to store, and if it exceeds the above numerical range, it may be difficult to manufacture the injection product in a spherical shape.
[0049] In the step of injecting the injection molding obtained from the above mixed solution into a calcium chloride solution and then stirring to crosslink, the crosslinking time may be 30 seconds to 3 minutes. Preferably, the crosslinking time may be 30 seconds to 1 minute. If the crosslinking time is less than the above numerical range, the injection molding obtained from the mixed solution may not sufficiently harden and thus may not be able to maintain its shape. If the crosslinking time exceeds the above numerical range, the injection molding obtained from the mixed solution may harden into a solid form, resulting in a hard texture.
[0050] In the step of mixing the washed spherical injection molded product with a xanthan gum solution after drying, the drying may be performed in a dryer at 35 to 80°C for 20 to 90 minutes. Preferably, the drying time may be 30 to 60 minutes. If the drying time is less than the above numerical range, the water absorption prevention effect may not be effective, and a large amount of moisture may be generated. If the drying time exceeds the above numerical range, the physical properties may become stronger, and the texture may be different from that of wild caviar when consumed.
[0051] In the step of mixing the dried spherical injection molding with the xanthan gum solution after drying the above-described dried spherical injection molding, the weight ratio of the dried injection molding to the xanthan gum solution may be 100:0.1 to 5. Preferably, the weight ratio may be 100:0.3 to 1. Most preferably, the weight ratio may be 100:0.5. Since xanthan gum increases viscosity depending on the amount added, it is preferable to use a 3% xanthan gum solution to prevent clumping of single caviar. If the xanthan gum solution is included in an amount below the above-described numerical range, a problem of moisture easily escaping may occur, and if it is included in an amount exceeding the above-described numerical range, it is difficult to maintain the shape of a single caviar, and the final product, cultured cell-based caviar, may have a lumpy shape.
[0052] Another embodiment of the present invention provides a cultured cell-based caviar manufactured by any one of the above manufacturing methods.

In addition, to measure the sugar content, 5 parts by weight of cultured cell-based caviar per 50 parts by weight of the total was added to distilled water and ground using a homogenizer for approximately 30 seconds. After centrifugation at 3500 rpm for 5 minutes using a centrifuge, only the supernatant was collected and the sugar content was measured using a refractometer (CAS, SUGAR-2PLUS). The results are shown in [Table 3].
