Abstract

The invention relates to the technical field of deep processing of aquatic products, and discloses a method for improving gel properties of fish myofibrillar protein based on combination of kelp polyphenols and a polyphenol oxidase. The method for improving the gel properties of the fish myofibrillar protein based on combination of the kelp polyphenols and the polyphenol oxidase includes the following steps: S1. extracting the fish myofibrillar protein; S2. taking the fish myofibrillar protein, adding a kelp polyphenol solution and the polyphenol oxidase, and then homogenizing and mixing; S3.performing cold storage on and standing an obtained mixture; S4. heating at 40-100 DEG C for 5-30 minutes; and S5. cooling and balancing to obtain a fish myofibrillar protein glue product. The methodfor improving the gel properties of the fish myofibrillar protein based on combination of the kelp polyphenols and the polyphenol oxidase enables the gel strength of the fish myofibrillar protein glueproduct to be effectively improved, is simple and easy to operate in process, and is convenient for industrial production.

Description

technical field [0001] The invention belongs to the technical field of deep processing of aquatic products, and in particular relates to a method for improving the gel properties of fish myofibrillar protein based on the combination of kelp polyphenols and polyphenol oxidase. Background technique [0002] Fish myofibrillar protein is similar to other muscle myofibrillar proteins in terms of functional properties, and is a structural protein group with important biological functions. The rheological properties of products such as cohesiveness, water retention, elasticity, and texture are closely related. The heat-induced gelation of myofibrillar proteins plays an important role in the structural properties of meat products, and its gel properties determine the yield, texture, adhesion, fat content, and water retention of the product. At present, gel products have problems such as insufficient elasticity, smoothness, and insufficient compactness, which makes how to improve th...
