Abstract

A method for preparing peptide calcium from fish bones, which uses fish bones as raw materials, uses subcritical water to treat fish bones under acidic conditions, uses dynamic high-pressure micro-jet to ultrafine fish bones, and enzymolyzes them with pepsin and compound flavor protease Fish bones, and then use microwave technology to process the fish bone enzymatic hydrolyzate, and finally spray-dry to make peptide calcium products. The invention adopts subcritical water technology to treat the mixture of fish bones and hydrochloric acid, which can effectively shorten the softening speed of fish bones and promote the dissolution of calcium ions; high-pressure micro-jet treatment can greatly reduce the particles of fish bones and improve the enzyme activity of subsequent fish bones hydrolysis efficiency; using pepsin and compound flavor protease to enzymatically hydrolyze the ultrafine fish bone can promote the transformation of protein into polypeptide and form a mixture of peptide and calcium; microwave heating can promote the chelation efficiency of polypeptide and calcium, Improve product quality; the invention can achieve the purpose of simultaneously utilizing protein and calcium in fish bones, and improves the utilization value of fish bones, a by-product of surimi processing.

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...
