Preparation method of pure fish soup powder
Technical Field
The invention belongs to the technical field of food processing, and mainly relates to a method for preparing pure fish meat soup powder.
Background
In the development of marine resources, 40-50% of by-products, such as fishbones, fish scales, fish viscera, fish skins and the like, are generated in the processing process of fish products in China, wherein the fishbones account for about 15%, and contain abundant proteins, high-quality fat, abundant essential trace elements such as calcium, phosphorus and the like, a plurality of bioactive substances with high biological value, such as chondroitin, fish bone collagen and the like; at present, most of fishbone byproducts in the market are utilized to prepare animal feed bone meal, part of fishbones are deeply processed by grinding the fishbone paste into fishbone paste by using a bone paste mill, and the fishbone paste is added into minced fillet products, so that the products need to be stored in a frozen state, the storage cost is increased, the utilization is not too wide, and the processing amount of the products is limited. In recent years, the yield of rainbow trout introduced and cultured in China is continuously increased, the amount of a processed byproduct fishbone is also increased, the rainbow trout fishbone contains high-quality protein, the fish oil in the fishbone has high nutritional value, the components comprise eicosapentaenoic acid, docosahexaenoic acid, linoleic acid, palmitic acid and the like, and the rainbow trout has necessary value for further deep processing of a powdery seasoning product with rich nutrition.
