Novel green grape antistaling agent

Abstract

An antistaling agent for green grape is prepared from the durable antistaling agent of grape (described in the Chinese patent whose application number is 01137211.7), oxidant, alkaline substance and gas absorbent through respectively shaping and proportional mixing. It can keep the active concentration of SO2 in packing container for green grape.

Description

technical field [0001] The present invention is a cold-chain storage and long-distance transport fresh-keeping method for fresh grapes, especially for the continuous release of SO 2 SO caused by preservation mode 2 Excessive accumulation will cause phytotoxicity and bleaching of grapes, and cause the stored grapes to lose their original flavor. It is a new type of green grape preservative invented. Background technique [0002] SO 2 For the development of grape storage and transportation preservation technology, the original California grape growers used SO produced by burning sulfur 2 To fumigate grapes until now people have designed various SO 2 Release agents have been formulated to preserve grapes for over eighty years. Practice has proved SO 2 It has a very significant fresh-keeping effect and is economical and convenient to use in grape fresh-keeping. In recent years, people continue to study deeply, and develop various grape fresh-keeping papers and fresh-keepin...

Problems solved by technology

These inventions have all adopted certain methods to prolong the SO 2 of the release period, but is usually guaranteed during SO 2 When valid in the long run, SO 2 The release rate in the early stage is faster, and the release amount is also larger. Due to the continuous release of SO 2 The fresh-keeping mode is to seal the preservative together with the grapes in a carton or plastic bag, thus causing SO 2 Excessive accumulation will cause phytotoxicity and bleaching of grapes, so that the stored grapes will lose their original flavor and their commerciality will decline.
