Problems solved by technology

As a deep-processing product of surimi, fish gluten has been sold in Japan and southeast China, with many varieties and good quality. The technology of using various freshwater and seawater fish as raw materials to prepare fish gluten has been very mature, but most of them use economical methods. Fish is used as raw material, so the price of fish gluten is either high, or the nutritional value is reduced due to the addition of a large amount of non-fish ingredients such as starch

Embodiment 1

[0014] Take a grass carp, clean it, remove the fish head, scales, viscera and skin, cut off the fish meat, weigh 3kg, add 15L of water and stir for 10 minutes, let it stand for 10 minutes, take out the fish meat and drain it, then add water in the same proportion and stir it, let it rest Place and drain the fish. For the third time, use 15L of 2g / L brine, stir slowly for 10 minutes, let stand for 20 minutes, take out the fish and drain. Put the fish meat into a meat grinder, coarsely grind it for 5 minutes into mince.

[0015] The fish skin, fish bone, fish tail and small miscellaneous fish are dried, sterilized, fishy and flavored with microwave equipment. Adjust the output power and feeding amount of the microwave so that the microwave operating frequency is 2450MHz, the power density is 2kW / Kg, and the time is 15min. The leftovers processed by microwaves are pulverized into 30-40 mesh powders with a roller mill. Then use a vibration mill to grind into a superfine powder o...

Abstract

The invention relates to a method for processing and producing fish gluten through fish leftovers such as fishbone, fishskin, fishtails and small trash fish, which belongs to the field of food processing. According to the method, the leftovers such as the fishbone, the fishskin, the fishtail and the small trash fish are crushed to be added into the fish gluten, the production cost is lower, the content of calcium and collagen of the fish gluten is higher than that of the common fish gluten, and the fish gluten has clean aroma, is fresh and tender, and is very suitable for the old and children as nutritional supplement food.

Description

technical field [0001] The invention relates to a method for processing fish gluten by using fish leftovers, such as fish bones, fish skins, fish tails, small miscellaneous fish, etc., and belongs to the field of food processing. Background technique [0002] Fish gluten is mainly processed with fish, water and some food accessories. According to nutritional analysis, the protein content of fish is 12-26%, which is close to poultry and higher than egg milk, and contains 11 kinds of amino acids necessary for the human body. The connection is loose and the water content is large, of which 60-90% is free water and a small amount of crystal water. Therefore, the meat is tender and delicious, easy to be absorbed by the human body, and the digestibility can reach 87-98%. Furthermore, the connective tissue and cartilage tissue of fish contain a large amount of unsaturated fatty acids, and the absorption rate of the human body can reach 95%. Fish also contain a variety of vitamins,...
