Abstract
The present disclosure belongs to the technical field of antifreezes, and relates to a reconstructed tamarind seed polysaccharide (TSP), and a preparation method and use thereof. In the present disclosure, a natural TSP is used as raw material. Depolymerization by cellulase unfolds dense self-aggregating coils of the natural TSP to form highly-solvated depolymerized long chains. A certain amount of strongly hydrophilic side-chain galactose is removed by β-galactosidase, and a local hydrophilic-hydrophobic ratio is adjusted to drive the assembly of depolymerized polysaccharide chains, thus forming a large-sized fibrous supramolecular structure. In this way, surface properties and an interface size effect of the reconstructed TSP participating in an ice crystal interaction are significantly improved, such that an ice recrystallization inhibition activity is significantly improved compared with that of the natural TSP. The reconstructed TSP breaks through objective limitation of a weak activity of the natural TSP-based ice recrystallization inhibitors.
