Embodiment 1

[0014] A low-value fish protein iron peptide is obtained by reacting a protein peptide with an amino acid sequence of HSASYSRCYCRCLRCRVLHPGCVNCYRCSR with ferrous ions.

[0015] A method for preparing low-value fish protein iron peptides, including deodorization treatment, preparation of fish protein peptides, and preparation of fish protein iron peptides. The specific operation steps are:

[0016] 1) Deodorization treatment: take the leftovers after processing aquatic products, clean them, add the leftovers to ozone water with a concentration of 5mg / L, rinse them for 20 minutes, rinse them with clean water, add water at a weight ratio of 1:4, and grind them into meat pulp. Ozone has a good deodorizing effect, prevents the reproduction of lactic acid bacteria, can prolong the storage time of raw materials, has no effect on the nutritional content of leftovers, and has a fresh-keeping effect;

[0017] 2) Preparation of fish protein peptides: Weigh the leftovers after deodorizati...

Embodiment 2

[0020] A low-value fish protein iron peptide is obtained by reacting a protein peptide with an amino acid sequence of HSASYSRCYCRCLRCRVLHPGCVNCYRCSR with ferrous ions.

[0021] A method for preparing low-value fish protein iron peptides, including deodorization treatment, preparation of fish protein peptides, and preparation of fish protein iron peptides. The specific operation steps are:

[0022] 1) Deodorization treatment: take the leftovers after processing aquatic products, clean them, add the leftovers to ozone water with a concentration of 6mg / L, rinse them for 18 minutes, rinse them with clean water, add water at a weight ratio of 1:4, and grind them into meat pulp. Ozone has a good deodorizing effect, prevents the reproduction of lactic acid bacteria, can prolong the storage time of raw materials, has no effect on the nutritional content of leftovers, and has a fresh-keeping effect;

[0023] 2) Preparation of fish protein peptide: Weigh the leftovers after deodorizatio...

Embodiment 3

[0026] Under the same preparation conditions, the effect of the molar ratio of peptide to iron on the iron content in fish protein iron peptide was analyzed. The results are shown in Table 1 below. Linearly, the iron content of fish protein ferritin peptides was highest when the molar ratio of peptide to iron was 2.5:1.

Abstract

The invention discloses a compound of iron and protein peptide from low-value fish. The compound is prepared through a reaction of ferrous ions with protein peptide which has an amino acid sequence of HSASYSRCYCRCLRCRVLHPGCVNCYRCSR. A preparation method for the compound comprises the following steps: with leftovers obtained after processing of aquatic products as a raw material, removing fishy smell; preparing fish protein peptide; and then preparing the compound of iron and the fish protein peptide. The invention has the following beneficial effects that the compound of iron and the fish protein peptide is rich and comprehensive in nutrients and high in purity, overcomes the problems of overstocking of raw fish and wasting of resources during production of low-value fish, improves the added value of low-value fish and has good market development potential; and the compound of iron and the fish protein peptide is free of toxicity, irritation, adverse and side effect and peculiar metal smell, good in in-vivo dissolvability, fast in absorption speed, high in absorption efficiency, stable in properties and long in shelf life.

Description

technical field [0001] The invention relates to the technical field of deep processing of fish products, in particular to a low-value fish protein iron peptide. Background technique [0002] In recent years, with the development and popularization of modern fishing technology, the intensity of fishing has increased, and marine fishery resources have declined year by year, especially large and medium-sized fish have been destroyed year by year. Destructive fishing has greatly damaged offshore fishery resources. Seriously, the main economic fish species are seriously depleted, which leads to the rapid development of small fish and shrimp in the food chain, followed by a gradual increase in the output of low-value fish in marine fishing. Accounting for 28% of the catch, these low-value fish are very poorly utilized in food processing. This kind of fish is rich in nutrition, has many varieties and large yields, and has great development value and utilization space. Many countr...
