Description
Technical field
The present invention relates to fruit and vegetable fresh-keeping agent, relate in particular to a kind of bi-component edible fruit and vegetable coating antistaling agent and application thereof.
Background technology
Fruits and vegetables is a requisite important substance in people's diet, but because the seasonality that fruits and vegetables produces is stronger, and the production of some fruits and vegetables also has very strong region, therefore solve the fresh-keeping green-keeping problem in fruits and vegetables transportation and the retail process, thereby improve the commodity value of fruits and vegetables, become at present a big hot topic problem of research both at home and abroad.Up to the present, the fresh-keeping of fruits and vegetables all carried out big quantity research both at home and abroad, and the focus of research concentrates on mainly on the coating-film fresh-keeping method, this mainly is because the coating-film fresh-keeping method has following advantages: good refreshing effect, technology is simple, and is with low cost, and equipment requires low.But all contain the unedible composition of human body in most of coating antistaling agent of reporting in the document, this has just limited their application on the fruits and vegetables of some kind greatly, because the skin of these fruits and vegetables is very thin, people can't remove when edible.In addition, although reported the natural fruit and vegetables coating antistaling agent in some patent, these antistaling agents have a common fatal shortcoming: not water-fast.This point is very important; because the method that all adopts refrigeration and other fresh-keeping measure to combine after a lot of fruits and vegetables are gathered is preserved; when fruits and vegetables being taken out from freezer when circulating the field; the water of fruits and vegetables surface condensation can dissolve not water-fast filming, thereby has lost the protection of filming and do not reach purpose to preserving fruit and vegetable utilizing.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of both direct-edible bi-component edible fruit and vegetable coating antistaling agent and the application thereof that possesses excellent water tolerance for the defective that overcomes above-mentioned prior art existence, green fruit and vegetable is carried out fresh-keeping guarantor, reduce moisture loss and rotting rate.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of bi-component edible fruit and vegetable coating antistaling agent is characterized in that, this antistaling agent is made up of A component and B component; Described A component comprises: polysaccharide, its weight percentage 1～10%, anticorrisive agent, its weight percentage 0.01～1%, surfactant a, its weight percentage 0.1～2%, antioxidant, its weight percentage 0.01～1%, water, its weight percentage 86～98%; Described B component comprises: waterproofing agent, its weight percentage 1～20%, surfactant b, its weight percentage 0.1～5%, solvent, its weight percentage 75～98.9%.
