Abstract

The invention relates to a method for preparing swimming bladder collagen powder. The method comprises the following steps: by taking dry swimming bladders as a raw material, washing, ordinarily crushing, soaking in water, further performing ultrasonic treatment, adding water to pulp to prepare swimming bladder pulp, adding papain to control enzyme enzymolysis, performing enzyme deactivation, centrifuging, filtering, and feeding the supernate into a spray-drying tower for spray-drying, thereby obtaining the swimming bladder collagen powder. According to the method, as ultrasonic auxiliary treatment and enzyme engineering techniques are adopted, the processing condition is gentle, the reaction process is easy to control, the swimming bladders are treated by using ultrasonic waves before enzymolysis so as to break the swimming bladder tissue and the cytomembranes, bio-enzyme can contact protein, the enzymolysis efficiency is improved, the process is advanced and reasonable, and because of the bio-enzyme, the rich protein in the swimming bladders can be converted into amino acid which is easy to digest and absorb by human bodies. The method is advanced in process and feasible in operation, the production cost is lowered, the product quality is improved, and the digestion rate is increased.

Description

technical field [0001] The invention relates to amino acids, peptides or proteins, in particular to a preparation method of swim bladder collagen powder. Background technique [0002] Swim bladder is the swim bladder of large yellow croaker, small yellow croaker, or Chinese sturgeon, locust, etc. of the cichlid family. Its main nutritional component is protein, with a content of more than 80% and a low fat content. It is an ideal high-protein and low-fat food. fatty food. Although the edible history of fish maw is long, in aspect of processing at present, the product variety of fish maw is single, except for cooking dishes, there are almost only dry products on the market. At the same time, it takes a lot of time and energy to process dried fish maw products in the cooking process before eating, and the final product is still tough and difficult to chew, which affects the appetite of many consumers; High temperature treatment is also not conducive to the retention of nutri...
