Fruit-vegetables antistaling agent, preparation and application thereof

Abstract

The invention provides a fruit and vegetable fresh-keeping agent, a preparation method and application thereof. The fresh-keeping agent uses burdock fructo-oligosaccharides as main composition and combines aqueous solution prepared by chitosan, ascorbic acid, salicylic acid, calcium chloride and acetic acid to treat fruit and vegetable, so that a fruit and vegetable system can obtain the improvedresistance, and a hyaloplasmic fresh-keeping membrane is formed on the surface of the fruit and the vegetable so as to effectively inhibit the growth of microbe, prevent moisture dissipation and contact between the fruit and the vegetable and air, and inhibit breath and transpiration, thereby greatly deferring aging of the fruit and the vegetable, and inhibiting putridity, mildew and rot. The fruit and vegetable fresh-keeping agent is applicable to storage and fresh-keeping for various fruits and vegetables with long fresh-keeping period and small consumption of nutrient materials.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and relates to a pollution-free, pollution-free and biologically safe fresh-keeping agent for fruits and vegetables and its preparation and application, in particular to the application of burdock extract-burdock fructooligosaccharides in fresh-keeping of fruits and vegetables. Background technique [0002] In our country, fruit and vegetable production has become a pillar industry of the rural economy. Abandoned later", the loss was heavy. Statistics show that if the loss of fruits and vegetables in our country is reduced by 3% to 5%, the annual loss of fruits and vegetables can be reduced by more than 2 million tons; if the loss of fruits and vegetables is reduced by 15%, the output value of fruits and vegetables can increase by 12 billion yuan. Therefore, reducing the rot loss of fruit and vegetable products, improving the utilization of agricultural resources, ...

AI Technical Summary

Problems solved by technology

Although these methods are successful to a certain extent, there are certain defects, such as low-temperature fresh-keeping storage and air-conditioning fresh-keeping storage, which require a large investment and are not easy to popularize; plastic films can inhibit the dehydration of fruits and vegetables, but they are easy to cause rot and peculiar smell; Organic fungicides and preservatives will remain on the skin of fruits and vegetables for freshness preservation, which is poisonous to the human body
