Breathing-controllable compound coating preservative made of porous material

Abstract

The invention discloses a breathing-controllable compound coating preservative made of a porous material. By using the breathing-controllable compound coating preservative made of the porous material, the problems that fruits are easy to rot and go bad, are not easy to preserve and store and generate alcohol are solved. The preservative comprises the following components: 0.05-1.5% of the porous material, 10-20% of beewax, 1-2% of vitamin E, 3-5% of pectin, 2-4% of lignin, 0.5-1.5 parts of cosolvent, 2-4 parts of dispersing agent and 30-40 parts of water. The preservative has the characteristics of pathogen inhibition, sensory quality keeping, low cost, convenience in operation when being used, long release period, uniform effect and the like. The quality of the fruits is ensured, meanwhile, the storage period and shelf life of the fruits are prolonged, and the economic loss generated because the fruits rot and go bad is effectively reduced.

Description

technical field [0001] The invention discloses a breathable controllable porous material composite film preservative, which solves the problems that fruits are easy to rot and deteriorate, produce alcohol, are difficult to keep fresh and are not resistant to storage. Background technique [0002] The production of tropical fruits in my country is very rich, such as mango, pineapple, banana, lychee, etc., and the ripening period is mostly in high temperature and high humidity seasons. Poor conditions and technology have caused great losses to fruit farmers and seriously affected the economic benefits of fruit growing areas. Postharvest fruit storage technology has become a bottleneck in the development of tropical fruits in my country. Although the fruit coating preservatives commonly used in the market slow down the rot process of fruits, at the same time, because the coating preservatives form an airtight preservative film layer on the fruit skin, it hinders the normal aero...

AI Technical Summary

Problems solved by technology

Although the fruit coating preservatives commonly used in the market slow down the rot process of fruits, at the same time, because the coating preservatives form an airtight preservative film layer on the fruit skin, it hinders the normal aerobic respiration of the fruit, causing the fruit to pass through without Oxygen respiration produces a certain amount of ethanol, acetaldehyde, etc., which accelerates the rot and deterioration of fruits. This is also the reason why commonly purchased fruits such as mangoes and pineapples will have peculiar smells such as alcohol, and they will not be fresh enough after being placed for a long time.
