AI Technical Summary

Technical Problem

In existing traditional Chinese medicine compositions containing animal peptides, small molecule animal peptides are extremely prone to absorbing moisture and clumping, and are oxidized and deactivated. They also have obvious bitterness and fishy smell. At the same time, the simple physical mixing process leads to large density differences among the components and poor product uniformity, making it difficult to achieve synchronous release and absorption in the gastrointestinal tract.

Method used

An electrostatic complex of animal peptides and acidic polysaccharides was formed in an environment of pH 4.0–4.5, and dispersed in a sugar matrix formed by isomaltooligosaccharide and potassium sorbate. The complex was then loaded onto a solid support to construct a stable encapsulation system. The interfacial interactions between the multiple components formed a polyelectrolyte complex with the characteristics of a "hydrophilic shell and hydrophobic core", which blocked the external contact pathway and achieved synchronous release.

Benefits of technology

It effectively prevents peptide oxidation and moisture absorption, improves sensory quality, ensures component homogeneity and synchronous release, and enhances product storage stability and bioavailability.

Abstract

The present application relates to the technical fields of traditional Chinese medicine preparation and health food processing, and discloses a kidney-tonifying and essence-filling composition containing animal peptides and medicine-food homologous raw materials, which is made of solid-phase carrier raw materials, acid polysaccharide extraction raw materials, animal peptides, oligoisomaltose, potassium sorbate and functional supplement raw materials. The composition is characterized in that: the acid polysaccharide and the animal peptides form an electrostatic complex under the induction of a liquid-phase environment with a pH of 4.0-4.5, and potassium ions are introduced to cross-link and lock, and finally, the complex is dispersed in a sugar matrix formed by oligoisomaltose and loaded on the surface of the solid-phase carrier. The present application effectively masks the fishy and rancid smell of the animal peptides by polysaccharide embedding and matrix solidification technology, blocks oxygen and moisture, solves the problem of easy moisture absorption and oxidation of the peptide raw materials, and realizes the efficacy synergy of the animal peptides and the plant extracts by scientific formula matching, so that the composition has significant kidney-tonifying and essence-filling effects and excellent storage stability.
