Molecular membrane fruit and vegetable antistaling agent made of edible material

Abstract

A molecular-membrane antistaling agent for fruit is prepared from the edible material chosen from protein, sugar or polyose, aliphatics, natural or synthetic high-molecular material and micromolecular material through preparing organic solution, aqueous solution, or emulsion, adding food aditive, stirring, heating or pressurizing for speeding up dissolution and cooling. Its advantages are low cost, high efficiency and no pollution.

Description

[0001] 1. Field [0002] The invention relates to a fruit and vegetable fresh-keeping agent, in particular to a molecular film fruit and vegetable fresh-keeping agent prepared entirely from edible materials. 2. Background technology [0003] my country has a large fruit planting area, many varieties and high yields, and the fruit producing areas are all over the country. The country's annual fruit output is about 50 million tons, accounting for 14% of the global total, ranking first in the world. Due to the backwardness of fruit preservation technology in our country, a large number of fruits rot and deteriorate during storage and transportation every year. According to statistics, the resulting loss accounts for about 30% of the total annual fruit output in the country. The lack of fresh-keeping methods for fruits has become a "bottleneck" that restricts the income of fruit farmers and hinders the development of my country's fruit industry. [0004] The backwardness of fres...

AI Technical Summary

Problems solved by technology

Because the fruit will produce ethylene gas with ripening effect during storage, when the concentration of this gas is high, it will still cause the fruit to rot and deteriorate, which is an obvious defect of this method;

[0011] 2. Storage in natural low-temperature warehouses. Putting fruits in cellars, caves or self-built warehouses, together with simple ventilation and humidity control measures, can prevent fruit rot or dehydration to a certain extent, but the reserves are limited and cannot be unloaded. Dramatic changes in temperature and humidity;

The disadvantage is that the cost of some raw materials is higher
