Abstract

The invention discloses a plant extract and a method for cross-linking collagen by using the plant extract as a biological cross-linker. The plant extract is an amomum villosum extract, wherein the amomum villosum extract contains polyphenol effective components. The plant extract is prepared through the following steps: firstly, cleaning, drying and crushing amomum villosum; secondly, extracting crushed amomum villosum powder in an extracting solution; thirdly, separating the extracting solution; fourthly, concentrating the extracting solution; fifthly, obtaining a concentrated plant extract solution or dehydrated plant extract powder. The plant extract has the benefits that by using the amomum villosum plant extract as the biological cross-linker, molecular chains of the collagen are cross-linked, the structure of the collagen can be stabilized, and the degradation resistance of the collagen is improved, so that the processing characteristics of a collagen product are improved, the physical properties and the texture characteristics are good, and the application prospect is wide.

Description

technical field [0001] The invention relates to the field of biochemistry, in particular to a plant extract and a method for crosslinking collagen as a biological crosslinking agent. Background technique [0002] Collagen exists in the connective tissue of animals and the human body, and is an important structural matrix for tissues, cartilage, skin and other organs. Animal collagen has rich nutritional value and is often extracted and used as a functional food raw material. However, due to the collagen itself The triple helix structure of collagen is easy to degrade, and it is difficult to maintain the stable triple helix structure of collagen, thus affecting the texture characteristics and thermal stability of foods with collagen as ingredients. Therefore, in order to improve the stability and anti-degradation ability of collagen, it is now necessary to cross-link collagen to generate collagen with a stable structure, thereby improving its anti-degradation ability and ther...
