Problems solved by technology

In addition, mangoes have strong cold sensitivity and are not resistant to low temperatures. Freezing damage is prone to occur in low temperature environments, while high temperature environments accelerate fruit rot, and sealing is easy to accelerate deterioration.
Post-harvest mangoes are also prone to rot due to pathogenic bacteria such as anthracnose and pedicle rot, and are extremely intolerant to storage.

Abstract

The invention provides a fruit and vegetable fresh-keeping agent prepared from the following raw materials in parts by weight: 1-10 parts of gum bletilla, 1-10 parts of Chinese medicinal plant and 0.01-0.2 part of nano titanium dioxide. The invention further provides a preparation method of the fruit and vegetable fresh-keeping agent. The fruit and vegetable fresh-keeping agent disclosed by the invention can be applied to preserving various fruits and vegetables, wherein the mango is taken as an experimental subject in an experiment, and the Chinese medicine extract with a remarkable inhibition function on pathogenicbacteria in the mango is prepared and then is firstly organically compounded with the traditional Chinese medicine gum bletilla and the nano titanium dioxide to prepare into the green and safe Chinese medicine fruit and vegetable fresh-keeping agent. The fruit and vegetable fresh-keeping agent disclosed by the invention breaks through the modified atmosphere preservation of fruits and vegetables, the natural bacteriostat application and the safety, and also brings very remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a fresh-keeping agent for fruits and vegetables. Background technique [0002] With the improvement of living standards and the popularization of nutritional intake knowledge, people's demand for fresh fruits has risen rapidly, and higher requirements have been put forward for the freshness and shelf life of fruits in the process of storage, transportation and sales. my country is a large fruit producing country, but due to the short shelf life of fresh fruits and the poor storage conditions of domestic fruits, post-harvest rot is common. According to data, 25% to 80% of my country's fresh fruits are lost after picking, which has not only caused great losses to fruit farmers, seriously affected economic benefits, but also brought serious pollution to the environment. Exploring high-efficiency, low-cost, and stable storage and preservation technology is the common goal of researchers in all related fields. Pursuing green, natur...
