Abstract

The invention belongs to the field of food processing and mainly relates to fish skin and pig skin compounded nutrition crystal jelly and a preparing method thereof. Fish skin and pig skin serve as raw materials, an extract gel solution is extracted through heat extraction, a primary extract gel solution is obtained through boiling, secondary gel extraction is carried out through steaming, the extract gel solution is cooled at a low-temperature to form the jelly food, the gel property pf the product is high, nutrition is rich, the texture is crystal clear, and the fat content is very low. The jelly prepared by compounding the pig skin and the fish skin is moderate in hardness, elasticity and toughness and has good heat resistance and stability.

Description

technical field [0001] The invention belongs to the technical field of food processing, and mainly relates to a nutritional crystal skin jelly made of fish skin and pig skin and a preparation method thereof. Background technique [0002] In the process of surimi production, a large amount of fish skin leftovers will be produced, and many fish skin leftovers are used for feed processing. In order to improve the utilization rate of fish skin and the added value of surimi products and reduce the cost of surimi production, intensive processing of fish skin has become an urgent problem to be solved in the field of food technology. Fish skin is rich in protein and various trace elements, and its protein is mainly macromolecular collagen, which is a high-quality raw material for producing gelatin. Gelatin is a natural nutritional food thickener, which will not make people fat after eating, and meets the dietary requirements of modern people. However, fish skin collagen is easier ...
