High viscoelastic surimi products (1)
In the processing and production of all kinds of surimi food, the choice of fish species and the freshness of fish are very important; it affects the elasticity of the products, so there is a certain limit on the amount of soybean and wheat protein powder mixed in surimi raw materials, and too much will weaken the elasticity of the products. In order to solve the elasticity problem of aquatic surimi products, a new method was used to make fish protein or mix it with plant protein to make protein fiber, and then mixed with surimi to produce surimi food with excellent viscoelasticity, which can make C-grade low-grade surimi elastic. Enhanced to more than A grade. The production method changes the original
