Embodiment 1

[0015] A processing method of low-value fish protein calcium peptides, including deodorizing treatment, preparation of fish protein peptides, preparation of fish bone meal, extraction of soluble calcium in fish bone meal, and preparation of fish protein calcium peptides. The specific operation steps are:

[0016] 1) Deodorizing treatment: cook the fish bones at 0.5MPa for 5 minutes, and then treat them at a microwave power of 450W for 2 minutes, then use a meat grinder to crush them. The combination of high pressure cooking and microwave has a good deodorizing effect, which can make the fish bones. The brittleness and color are the best, and it has no effect on the nutritional content of fish bones;

[0017] 2) Preparation of fish protein peptides: Weigh the fish bones after deodorization, add water, adjust the pH to 6.5, add 1000 U / g papain and flavor protease mixture, the weight ratio of papain and flavor protease mixture in the mixture is 0.5: 1.5, enzymatic hydrolysis for 5h, a...

Embodiment 2

[0022] A processing method of low-value fish protein calcium peptides, including deodorizing treatment, preparation of fish protein peptides, preparation of fish bone meal, extraction of soluble calcium in fish bone meal, and preparation of fish protein calcium peptides. The specific operation steps are:

[0023] 1) Deodorizing treatment: cook the fish bones at 0.6MPa for 6 minutes, then treat them at a microwave power of 460W for 2 minutes, and then use a meat grinder to crush them. The combination of high pressure cooking and microwave has a good deodorizing effect, which can make the fish bones. The brittleness and color are the best, and it has no effect on the nutritional content of fish bones;

[0024] 2) Preparation of fish protein peptides: weigh the fish bones after deodorization, add water, adjust the pH to 6.5, add 950U / g of papain and flavor protease mixture, the weight ratio of papain and flavor protease mixture in the mixture is 1: 1. Enzymatic hydrolysis for 4~6h, af...

Embodiment 3

[0029] Under exactly the same conditions of preparation, the effect of the molar ratio of peptide to calcium on the calcium content in fish protein calpeptide was analyzed. The results are shown in Table 1 below. The data can be obtained: the ratio of peptide to calcium on the calcium content of fish protein calpeptide The effect is non-linear. When the molar ratio of peptide to calcium is 3.5:1, the calcium content of fish protein calcium peptide is the highest.

Abstract

The invention discloses a processing method of low-value fish protein calcium peptide. The processing technology uses low-value fish bones as raw materials, undergoes deodorization treatment, preparation of fish protein peptides, preparation of fish bone powder, extraction of soluble calcium in fish bone powder, Preparation steps of fish protein calcium peptide Fish protein calcium peptide was prepared. The beneficial effects are: the protein calcium peptide of the present invention is rich in nutrition and comprehensive, and the product has high purity, solves the problem of backlog of raw material fish and waste of resources in the production process of low-value fish, increases the added value of low-value fish products, and has great market development potential; the protein Calcium peptide is non-toxic, non-irritating, and has good solubility in the body. It not only has excellent compatibility with various nutrients including vitamins and antibiotics, and has a synergistic effect, but also the human body can absorb protein calcium peptide through the absorption route of protein peptide, and the absorption speed Fast, 2 to 3 times that of inorganic calcium, easy to be accepted by consumers; the processing technology of the present invention has low production cost, can be designed into fully automatic operation, and has high production efficiency.

Description

Technical field [0001] The invention relates to the technical field of deep processing of fish products, in particular to a processing method of low-value fish protein calcium peptides. Background technique [0002] In recent years, with the development, promotion and popularization of modern fishing technologies, the fishing intensity has become greater and the marine fishery resources have been declining year by year, especially the large and medium-sized fish have been destroyed year by year. The devastating fishing damages the offshore fishery resources. Seriously, the major economic fish species have been severely depleted, causing the rapid development of small fish and shrimp in the food chain. Following this, the output of low-value fish in marine fishing has gradually increased. Such fish, shrimp and aquatic products are processed in general It accounts for 28% of the catch, and these low-value fish are very low-utilized in food processing. This kind of fish is rich in ...
