AI Technical Summary

Technical Problem

Commercially available squeezable jellies have a limited range of flavors and poor squeezability. Furthermore, the excessive use of different types of adhesives can cause the colloids to clump together during the dissolution process, affecting product quality.

Method used

Fish skin collagen peptides were prepared by using fish skin collagen peptides with composite gel, metal ions, citric acid and other components. The enzymatic hydrolysis process was optimized to prepare fish skin collagen peptides. The ratio of the composite gel and the sol conditions were determined to prepare absorbable jelly with elasticity, adhesiveness, chewiness and good water retention.

Benefits of technology

The prepared squeezable jelly is superior to commercially available products in terms of nutrition, taste, and squeezability. It has good water retention and sensory evaluation, and solves the problems of monotonous taste and poor squeezability.

Abstract

The invention relates to the technical field of food processing, in particular to a preparation method and application of fish skin collagen peptide, absorbable collagen jelly and a preparation method of the absorbable collagen jelly. The invention provides a preparation method of fish skin collagen peptide. The preparation method comprises the following steps: firstly, mixing and boiling freeze-dried fish skin and a phosphate buffer solution, and then carrying out enzymolysis; the preparation method comprises the following steps of: performing enzymolysis on fish skin collagen peptide, centrifuging an enzymolysis product, taking supernate, and drying to obtain the fish skin collagen peptide which can be used for preparing an anti-anxiety product. According to the invention, the composite gel, metal ions, citric acid and fish skin collagen peptide are compounded to obtain the smokable jelly which has certain elasticity, adhesiveness and chewiness and also has good water binding capacity and sensory evaluation.
