Banana fresh-keeping and variable-temperature gas-regulation ripening technique process flow

Abstract

The present invention discloses a banana preservation and variable-temperature air-adjusting ripening flow. Fruit lossless harvest, batch processing and vacuum packaging are carried out by constructing a banana air-adjusting storehouse; air-adjusting preservation and a series flow of variable-temperature air-adjusting ripening are utilized for banana preservation and accelerating maturity. The flow can obviously improve the exterior and interior quality of the banana finished product and achieve the controllability of ripening period. The product can be on a par with imported banana and has the advantages of dense fruit flavor, good taste, long shelf life, and the like, thus having good market prospect.

Description

Technical field [0001] The invention relates to a fresh-keeping and ripening process of fruits, in particular to a technical process of banana fresh-keeping and variable temperature and controlled atmosphere ripening. Background technique [0002] Banana is one of the famous and high-quality fruit varieties in the southern provinces of my country. It has the characteristics of aromatic taste and rich nutrition. The pulp is rich in glucose, fructose, vitamin C and various essential amino acids. It is a good fruit with a huge consumer market. At present, the total national output exceeds 6 million tons, and the banana industry occupies a very important position in agricultural income. However, for a long time, due to the backwardness of post-harvest preservation and ripening technology, most of the post-harvest products are simply soaked in ethephon liquid, and then packed in cartons and transported to all parts of the country. Distributors put them on the market after ripeni...

Problems solved by technology

However, for a long time, due to the backwardness of post-harvest preservation and ripening technology, most of the post-harvest products are simply soaked in ethephon liquid, and then packed in cartons and transported to all parts of the country. Distributors put it on the market after ripening on the spot. The internal quality is poor, the appearance is not beautiful, the product grade is low, and the market competitiveness is not strong, which seriously affects the market price of bananas. Compared with imported bananas, the retail price is 2-3 times lower.

This technology is aimed at this situation. According to the principle of controlled atmosphere preservation technology for fruits, the controlled atmosphere storehouse is used to preserve freshness of bananas and accelerate ripening with variable temperature and controlled atmosphere, so as to solve the common problems in the banana industry that the appearance quality is poor and it is difficult to compete with imported bananas for the market.
