Abstract

The invention relates to a food coating preservative containing water-soluble soybean polysaccharides. The preservative can also contain an enhancer, a plasticizer and other auxiliary components. Thepreservative has good film-forming property and antibacterial property, compared with the coating preservation for eggs which is carried out by using chitosan coating liquid and paraffin coating liquid, a water-soluble soybean polysaccharide coating has the advantages of lower water permeability rate, better preservation effect, a wide range of sources of raw materials, low production cost and edible safety.

Description

Technical field: [0001] The invention relates to a coating film preservative for food, in particular to a coating film preservative containing water-soluble soybean polysaccharide. Background technique: [0002] Many fresh foods, such as eggs, fruits, vegetables, etc. have harsh storage conditions, short shelf life, and are easily spoiled during storage and transportation. Coating fresh-keeping on the surface of these foods is a method to prolong the shelf life. [0003] For example, eggs that have not been cleaned and disinfected often carry a large number of bacteria, endangering the health of consumers. Cleaning the eggs will destroy the protective effect of the eggshell membrane, which is more likely to cause spoilage. Therefore, after the eggs are washed, they must be coated with a film to keep them fresh in order to extend the shelf life of the eggs. [0004] It is well known that coating films with non-edible materials such as paraffin can affect human health. [...
