Problems solved by technology

At present, the commercially available surimi products are mainly frozen products, which have low moisture content and high starch content, and most of them have high hardness and poor tenderness
Fish balls, also known as fish balls, are the traditional and most representative surimi products in my country. There are many categories, but due to different local characteristics, fish balls have obvious differences in material selection, production process, taste and flavor, etc.
Minced fish balls in clear soup, Shagou fish balls, Sizhen fish balls and other surimi products are popular among consumers because of their tender taste and delicious taste. High, prone to juice loss, protein freezing denaturation, microbial growth, etc., resulting in a decline in edible quality, difficult to preserve, so most of them can only be eaten in dine-in, and the sales and distribution range is extremely narrow. How to improve the water holding capacity of high-moisture fresh and tender surimi products and prolong the product Shelf life is a key technical problem to be solved urgently in the development of fresh and tender surimi products
[0003] Although exogenous additives and coating preservation technology have been applied in the field of surimi products or food preservation, the moisture content of currently commercially available surimi products is mostly between 73% and 80%, while fresh and tender fish such as fish balls in clear soup The moisture content of surimi products is as high as 85%, and the juice loss and food quality decline are more likely to occur during the refrigerated process. It is more difficult to keep fresh. Its water retention properties prolong the shelf life of the product

Abstract

The invention discloses a method for improving the water holding capacity of fresh and tender fish balls and prolonging the refrigeration shelf life of the product. The method comprises the steps of chopping, wherein semi-unfrozen minced fillets are cut into small pieces, ice water is added, and chopping is carried out; slat chopping, wherein salt is added, and chopping is carried out; mixing chopping, wherein an exogenous additive is dissolved in a small amount of water, then the dissolved exogenous additive is added into the minced fillets, and chopping is carried out; forming, wherein a fish ball forming machine is used for forming; gelatinization, wherein gelatinization is carried out by adopting a two-stage heating method; cooling, wherein gelatinized fish balls are put in cold waterfor cooling; chitosan coating, wherein the fish balls are put and soaked in a glycan solution for film coating; packaging, wherein vacuum packaging is carried out on the fish balls by adopting a boiling bag; thermal sterilization treatment and refrigeration are carried out. The invention provides a method for improving the quality of the high-moisture fresh and tender fish balls and prolonging thestorage period. The prepared product is pure white in color, fine, smooth, soft and tender in taste, and convenient to eat, not only meets the needs of modern consumers for convenient and fast products, but also is more conductive to achieving industrial production of traditional minced fillet products.
