Abstract

A processing method for high-calcium surimi products, which uses subcritical water and acetic acid to jointly treat fish bones, uses high-pressure micro-jet to ultrafine the fish bones, mixes the refined fish bones with thawed surimi, and then crushes them. Add glutamine transaminase for cross-linking reaction, and finally produce high-calcium surimi products through microwave segmental heating. The invention uses subcritical water combined with acetic acid to treat fish bones, which can effectively shorten the softening speed of fish bones and promote the dissolution of calcium ions; the high-pressure micro-jet treatment can greatly reduce the particles of fish bones, and reduce the high-calcium surimi after adding fish bones The discomfort of the product can improve the fineness of the product; the cross-linking of transglutaminase can fuse the ultra-fine fish bone and surimi to form an overall network structure, and enhance the uniformity of high-calcium surimi products; microwave heating can make high-calcium surimi The surimi products quickly cross the gel deterioration temperature zone, and the high and low power microwave segmental heating can improve the quality of high calcium surimi products.

Description

technical field [0001] The invention relates to a technology for processing high-calcium surimi products by using subcritical water combined with acetic acid treatment, dynamic high-pressure micro-jet treatment and glutamine transaminase cross-linking, and belongs to the field of surimi product processing. Background technique [0002] Surimi product is a new type of fish processing product developed in recent years. It has the advantages of high protein, low fat, safety and health, and is loved by consumers. However, currently the raw material for surimi processing on the market is only fish meat, and the remaining fish bones after harvesting the meat are discarded or simply crushed and used as feed, which not only reduces the processing utilization rate of fish raw materials, but also increases the production cost of surimi products. Caused waste of resources and environmental pollution. [0003] Fish bones are rich in nutrients, such as protein, calcium, etc. Regular con...
