Freshness keeping material and preparation method thereof

Abstract

The invention relates to a corrosion resisting and freshness keeping technology of vegetables and fruits in storage and transportation, and especially relates to a freshness keeping material for making vegetable and fruit storage and transportation circulating boxes, and a preparation method thereof. The freshness keeping material is characterized in that the freshness keeping material is composed of 70-80wt% of a high-molecular resin, 12-20wt% of far-infrared emission powder, 5-10wt% of tourmalinite powder and 1-3wt% of nano-silver powder. The material can be used for the sterilization, disinfection and mildew resistance of stored and transported vegetables and fruits, and can generate a large amount of negative ions and far infrared rays to realize the storage time prolongation and freshness keeping of the vegetables and the fruits and reduce the loss brought by mildew corruption in the transportation process.

Description

technical field [0001] The invention relates to anti-corrosion and fresh-keeping technology of vegetables and fruits during storage and transportation. In particular, it relates to a fresh-keeping material and a preparation method for manufacturing a vegetable and fruit storage and transportation turnover box. Background technique [0002] During the storage and transportation of the current vegetables and fruits, due to the high moisture content, the storage time is too long to generate heat, so the vegetables and fruits transported are prone to mildew and corruption, causing great losses. In the existing life, when people transport vegetables and fruits, they all use various methods to keep fresh the vegetables and fruits in the box, such as freezing method, ice coat method, fresh-keeping bag or fresh-keeping agent method. But there are also some problems in these methods, such as the short storage time and the decline in the quality of fruits and vegetables. When stored...

AI Technical Summary

Problems solved by technology

When stored in fresh-keeping bags, due to the increase of humidity in the bag, when the transportation distance is long, the moisture of fruits and vegetables will evaporate, resulting in many dewdrops on the surface of fruits and vegetables and the inner wall of fresh-keeping bags, which can cause the quality of fruits and vegetables to deteriorate, lose or reduce the original flavor and taste

The use of preservatives, preservatives, vulcanization, etc. has polluted vegetables and fruits and caused harm to people's health.
