Problems solved by technology

The controlled atmosphere storage method has huge investment, high technical difficulty, strict management and control requirements, huge energy consumption, and takes up a lot of resources, which is not suitable for my country's national conditions
The refrigeration method is widely used in our country, but some fruits and vegetables are prone to chilling injury when stored at low temperature for a long time, so its application is also limited

Abstract

The invention discloses a natural fruit and vegetable sterilizing fresh-keeping agent, preparation and a use method thereof, which belongs to the technical filed of sterilizing fresh-keeping agent. Every 1L sterilizing fresh-keeping agent comprises the following compositions by weight: 0.1 to 20 grams of grape seed extract, 1 to 50 milliliters of absolute ethyl alcohol, 0 to 0.5 milliliter of Tween-80, and the balance being sterilized water. The method for preparing the sterilizing fresh-keeping agent comprises the following steps: under the conditions of normal temperature and normal pressure, the grape seed extract, the absolute ethyl alcohol are added into the sterilized water, the Tween-80 is added to the mixed solution, and the sterilized water is added into the mixed solution for constant volume; and a glass rod is used for stirring the mixed solution uniformly to obtain the natural fruit and vegetable sterilizing fresh-keeping agent. The use method comprises the following steps: fruits and vegetables are soaked in the natural fruit and vegetable sterilizing fresh-keeping agent, or are soaked at negative pressure, and then the fruits and vegetables are taken out and are dried for further storage. The natural fruit and vegetable sterilizing fresh-keeping agent well solves the problems of rot and reduced quality after picking for the fruits and the vegetables, has low cost, and can effectively reduce use and residual quantity of chemical agents without causing environmental pollution, thereby having great value for development and application.

Description

technical field [0001] The invention belongs to the technical field of bactericidal and fresh-keeping agents, in particular to a natural fruit and vegetable bactericidal and fresh-keeping agent and its preparation and use method. Background technique [0002] Our country is a large agricultural country, and the fruit and vegetables have a large planting area. However, due to poor fresh-keeping treatment, the losses caused every year are staggering. From harvesting to sales, the annual loss rate of fruit is 20-25%, and the annual loss rate of vegetables is 30%. The annual loss of fruits and vegetables due to rot is hundreds of millions of tons, and the economic loss reaches 75 billion yuan. [0003] The main components of grape seed extract are proanthocyanidins, including four monomers of catechin, epicatechin, gallic acid and gallic acid-3-O-epicatechin, and polymers based on these monomers, which are An important secondary metabolite of grapes, which has strong antioxidan...
