Embodiment 1

[0028] A preparation method for fresh fish juice, comprising the following steps:

[0029] (1) Enzymolysis: Take an appropriate amount of fish meal to process the squeeze liquid, add 0.3% (m / v) compound protease A-1 and 0.2% (m / v) papain, stir to fully dissolve it, and place it in a 60°C refrigerator. On a constant temperature shaker, shake at 110r / min for 5 hours for enzymatic hydrolysis. After the end of the enzymatic hydrolysis, immediately inactivate the enzyme in a 95°C water bath for 15 minutes.

[0030] (2) Koji making: Weigh 133g of soybean meal and 100g of bran, add 180mL of water, mix well, soak for 5 hours, cook and sterilize at 121℃ for 40min, after the sterilization, let the mixed material cool down to about 40℃ , add 2‰ (m / m) strains, mix evenly, spread a layer of sterilized wet gauze on the sieve, transfer the mixture after adding the strains into the sieve, and then cover the sieve with a Layer wet gauze, and finally place the sieve with the material in an inc...

[0035] A preparation method for fresh fish juice, comprising the following steps:

[0036] (1) Enzymolysis: Take an appropriate amount of fish meal to process the squeeze liquid, add 0.3% (m / v) compound protease A-1 and 0.2% (m / v) papain, stir to fully dissolve it, and place it in a 60°C refrigerator. On a constant temperature shaker, shake at 110r / min for 5 hours for enzymatic hydrolysis. After the end of the enzymatic hydrolysis, immediately inactivate the enzyme in a 95°C water bath for 15 minutes.

[0037] (2) Koji making: Weigh 155g of soybean meal and 117g of bran, add 240mL of water, mix well, soak for 5h, cook and sterilize at 121°C for 40min, after the sterilization, let the mixed material cool down to about 40°C , add 2‰ (m / m) strains, mix evenly, spread a layer of sterilized wet gauze on the sieve, transfer the mixture after adding the strains into the sieve, and then cover the sieve with a Layer wet gauze, and finally place the sieve with the material in an incuba...

Abstract

The invention provides a preparation method of fish sauce. According to the preparation method, fish meal processing squeezing liquid is used as a raw material, the raw material protein is rapidly degraded by adding composite enzyme, and then the fish sauce is prepared by adding koji fermentation, wherein the bitterness produced by the enzymolysis can be effectively improved by virtue of the kojifermentation, and the sauce fragrance can be achieved. The fish sauce prepared in the preparation method provided by the invention is brownish red, uniform in color, clear, transparent, slight in fragrance and free from odor; and the content of amino acid nitrogen can reach 0.68 g / 100mL, the volatile salt nitrogen content is less than 109 mg / 100mL, and the table salt content is less than 16.2 g / 100mL. The preparation method is low in production cost, can effectively improve the product flavor, and can solve the problems of protein resource waste and environmental pollution.

Description

【Technical field】 [0001] The invention relates to the technical field of aquatic product processing, in particular to a processing method for producing fresh fish juice by using fish meal processing squeeze liquid as a raw material. 【Background technique】 [0002] In recent years, my country's low-value fish processing has made great progress compared with the past, and many low-value fish products have been developed, such as fish meal, fish oil, seasoning, surimi products, etc. Among them, the production of fish meal has always been the development and utilization of low-value fish products. The main means of fish protein. However, a large amount of waste water and fish juice will be produced in the process of fishmeal processing. For every ton of fishmeal produced, about 2-3 tons of waste squeeze liquid will be produced. Except for a small part of these fishmeal processing squeeze fluids that can be recycled to prepare low-grade fishmeal, or process some low-grade product...
