Problems solved by technology

[0009] However, for a long time, my country has not effectively utilized these resources. Except for a small amount of them being used to produce fertilizer or feed, and to prepare chitin, most of them are thrown away as garbage, which not only causes a serious waste of resources, but also pollutes the environment.

Abstract

The present invention relates to a prawn biological protein calcium preparation method, which comprises: selecting head and shell of prawn as raw materials, carrying out washing, drying and crushing, adding water to mix, adopting a NaOH solution to adjust the pH value, adjusting a temperature, adding papain to carry out enzymolysis to obtain an enzymolysis solution, carrying out enzyme inactivation on the enzymolysis solution, carrying out centrifugation to obtain a supernatant, removing impurities from the supernatant through a tubular membrane, adopting an ultra-filtration membrane with a molecular weight cutoff of 5000 Da to carry out an ultra-filtration treatment to obtain a trapping solution, and carrying out vacuum concentration and spray drying on the trapping solution to obtain the prawn biological protein calcium. The prawn biological protein calcium has characteristics of high absorption rate and good solubility, and is a novel calcium agent with good water solubility and high biological value. The preparation method has characteristics of reasonable preparation process, simple preparation, strong operability, and easy industrial production achievement.

Description

technical field [0001] The invention relates to the manufacture of aquatic food products, in particular to a method for preparing prawn biological protein calcium. Background technique [0002] We know that calcium is an indispensable macroelement for the human body. Calcium deficiency in adults will inevitably lead to osteoporosis, while calcium deficiency in infants and young children will lead to Kurutu's disease and dysplasia. For a long time, the main measure of human calcium deficiency is calcium supplementation. The effect of calcium supplementation mainly depends on the degree of absorption of calcium by the human body, and its absorption is closely related to the characteristics of calcium preparations. The existing calcium preparations in my country mainly include: calcium carbonate, calcium phosphate, calcium lactate, calcium gluconate, calcium acetate and active calcium. These calcium preparations all have shortcomings such as poor water solubility and low abs...
