METHOD FOR PRODUCING A FISH ROE ANALOGUE Russian patent published in 2022 - IPC A23L17/30 

FIELD: food industry.

SUBSTANCE: invention relates to the food industry, in particular, to a method for producing an analogue of roe of sturgeon and salmon fish species. Method for producing a fish roe analogue involves the preparation of an initial mixture for forming roe grains, including a fat mixture, a protein-containing component, an aqueous phase, and an aqueous dye solution. In order to prepare an emulsion thereof, the fat mixture and the aqueous phase are heated to a temperature of 65 to 78°C, emulsified while stirring at a speed of the stirrer of 2,850 to 3,000 min^-1 for 20 minutes, followed by cooling to a temperature of 38 to 40°C; wherein the aqueous phase contains Geleon 102 structure-forming agent, dry egg yolk, potassium sorbate, sodium benzoate, and water, and fish oil and vegetable oil at a ratio of 1:1 are used as a fat mixture. Ovarian fluid is used as a protein-containing component, wherein said fluid is pretreated by electrolysis in the anode zone to a pH value of 4.0 to 4.5 while supplying an aqueous solution of sodium chloride with a concentration of 1% to the cathodic zone at a current strength of 0.5 to 0.6 A, a voltage of 36 V, and a flow rate of the ovarian fluid and the sodium chloride solution in the corresponding zones of 1 to 10 cm³/h. The roe grains are then cooked by mixing, at a ratio of 1 to 10:1, with an emulsion containing sodium alginate, table salt, calcium chloride, sugar, potassium sorbate, sodium benzoate, citric acid, fish oil, and water. Then the grains are held at a temperature of 2 to 4°C for 10 hours.

EFFECT: proposed method for producing a fish roe analogue ensures the production of a finished product with taste and organoleptic properties similar to those of natural caviar and capable of preserving the taste qualities in long-term storage.
