Abstract

The invention discloses a supramolecular material film constructed by biomass extracted small molecules. The supramolecular material film comprises biological polyhydroxy small molecules and small biological molecules containing carboxyl and hydroxyl groups, and a weight ratio of the polyhydroxy small molecules to the small biological molecules containing carboxyl and hydroxyl groups is 0.01: 1-1: 0.01. The invention also discloses a preparation method of the supramolecular material film. The preparation method comprises the following steps: 1) preparing a solution; 2) preparing a coating solution; and 3) coating and film forming. The invention belongs to the technical field of food preservation, and particularly relates to the supramolecular material film constructed by biomass extracted small molecules and the preparation method of the supramolecular material film.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and specifically refers to a supramolecular material film constructed by extracting small molecules from biomass and its preparation and application. Background technique [0002] With the development of science and technology, people's living standards are gradually improving, especially the demand for healthy food is increasing rapidly, and the output of fruits and vegetables is increasing rapidly. [0003] Fresh fruits and vegetables have high nutritional value and are convenient to eat, but fruits and vegetables are also a kind of products that can carry out breathing activities, and can still maintain an active metabolism after harvesting. However, due to its soft texture, easy mechanical damage, strong metabolism and high microbial sensitivity, and concentrated time to market, it is extremely perishable after harvest, causing serious waste of resources, economic losses and environ...
