Abstract

The invention discloses a processing technique of low-value fish high-calcium protein powder. The processing technique comprises the following steps of treating raw materials, performing enzymolysis and enzyme deactivation, performing separation and concentration, performing spray drying and performing mixing and blending. The processing technology has the beneficial effects that the low-value fish high-calcium protein powder obtained through the processing technology is high in protein content, low in fat content, high in calcium content, rich in nutrition, good in taste, easy to absorb, suitable for old and young people, free from any side effects, and capable of improving constitutions and enhancing immunity after being used for a long term; the comprehensive utilization of low-value fish is increased, the cost of the raw materials is reduced, the environmental pollution is reduced, the added value of the low-value fish is increased, the market is enriched, and the processing technique has favorable prospects; and the process of the processing technology is simple, the enzymolysis time is short, the production efficiency is high, and the processing technology is suitable for industrialized application.

Description

technical field [0001] The invention relates to the field of aquatic product processing, in particular to a processing technology of low-value fish high-calcium protein powder. Background technique [0002] For a long time, the sales of freshwater fish have been mainly fresh and live, with very little processing. Freshwater fish are mostly concentrated in the market after autumn, and their production often far exceeds the local consumption. The phenomenon of "pressure in ponds" and "difficulty in selling fish" even occurs, causing huge economic losses. Due to the oversupply in the market, the price of fish has fallen, which has seriously dampened the enthusiasm of fisheries and farmers for production. Therefore, if we do not accelerate the development of comprehensive utilization of freshwater fish processing and improve the economic and social benefits of freshwater fish products, the continued development of the aquaculture industry will be affected. [0003] Low-value f...
