Abstract

According to a processing method of a high-calcium minced fish product, subcritical water and acetic acid are used to jointly treat fish bones, high-pressure microjet is adopted to perform super-refinement on the fish bones, the refined fish bones and unfrozen minced fish are uniformly mixed and blended, glutamine transminase is added for a crosslinking reaction, and finally, the high-calcium minced fish product is produced through sectioned microwave heating. The subcritical water is used for treating the fish bones in combination with acetic acid, the fish bone softening speed can be reduced effectively, and dissolving out of calcium ions can be promoted; through high-pressure microjet treatment, fish bone particles can be greatly reduced, discomfort of the high-calcium minced fish product after the fish bones are added is reduced and the fineness of the product is increased; the super-refined fish bones and the minced fish can be fused to form an overall network structure through glutamine transaminase crosslinking and the uniformity of the high-calcium minced fish product is enhanced; microwave heating can make the high-calcium minced fish product quickly cross a gel degradation temperature zone, and the quality of the high-calcium minced fish product can be improved through high / low-power sectioned microwave heating.

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...
