Abstract

The invention discloses a method for preparing peptide calcium by using fish bone. The method comprises the following steps: by taking fish bone as a raw material, treating the fish bone by using subcritical water under an acid condition, performing super-fine comminution on the fish bone by using dynamic high-pressure micro jet, performing enzymolysis on the fish bone by using pepsase and composite flavourzyme, treating enzymatic hydrolysate by using a microwave technique, and performing spray drying, thereby obtaining a peptide calcium product. As a mixture of the fish bone and hydrochloric acid is treated by using the subcritical water technique, the speed of softening the fish bone can be effectively increased, and calcium ion digestion can be promoted; due to high-pressure micro jet, the granules of the fish bone can be greatly reduced, and later fish bone enzymolysis efficiency can be improved; the pepsase and the composite flavourzyme are adopted for enzymolysis on the fish bone after super-fine comminution, then conversion of proteins to polypeptide is promoted, and a mixed liquid of peptide and calcium can be formed; due to microwave heating, the chelation efficiency of the peptide and the calcium can be promoted, and the product quality can be improved; by adopting the method, the purpose of utilizing the proteins and the calcium in the fish bone simultaneously can be achieved, and the utilization values of the byproduct, namely the fish bone generated in minced fillet processing, can be increased.

Description

technical field [0001] The invention relates to a method for preparing peptide calcium by using fish bone as a raw material, combined with subcritical water technology, dynamic high-pressure micro-jet treatment, protease enzymolysis, microwave treatment and spray drying, and belongs to the field of preparation of peptide calcium products. Background technique [0002] Fish is one of the main sources of protein ingested by humans, and it has the characteristics of low price, green and safe. With the improvement of people's living standards and the acceleration of the pace of life, more and more consumers love convenient, quick, green and nutritious food. Among them, surimi products are a new type of fish product developed in recent years. The raw material for surimi processing is fish meat, and the remaining fish bones after harvesting are discarded or simply crushed and used as feed, resulting in waste of resources and environmental pollution. [0003] Fish bones are rich i...
