Storage method of punica granatum through controlled atmosphere cold storage warehouse

Abstract

The invention discloses a storage method of punica granatum through a controlled atmosphere cold storage warehouse, and belongs to the technical field of storage of punica granatum. The storage methodcomprises the following steps of step 1, before the punica granatum is warehoused, thoroughly cleaning the inner part of the controlled atmosphere cold storage warehouse with alcohol, performing ventilating and performing drying by airing; step 2, adding the punica granatum in the controlled atmosphere cold storage warehouse; step 3, adjusting the oxygen concentration in the controlled atmospherecold storage warehouse to be 3%, wherein the concentration of carbon dioxide is 3%, and the concentration of nitrogen is 94%; step 4, adjusting the inner pressure of the controlled atmosphere cold storage warehouse to 10-70mmHa through an air pressure controller, and lowering the temperature of the inner part of the controlled atmosphere cold storage warehouse to be 2-3 DEG C through an air conditioner; and step 5, moving out a collecting box loaded with the punica granatum, wherein the punica granatum revives after being taken out for one week, can be totally sold, and can also be transferred to a freezer for slow selling. The storage method solves the problem that in the prior art, the punica granatum is short in storage time, besides, protection of a balancing bag of the controlled atmosphere cold storage warehouse can be realized, the service life of the balancing bag of the controlled atmosphere cold storage warehouse can be effectively prolonged, and smooth operation of the storage process of the punica granatum can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of pomegranate preservation, in particular to a method for preserving soft-seed pomegranate in a controlled atmosphere store. Background technique [0002] As we all know, modified atmosphere preservation is to use the method of controlling the gas ratio to achieve the purpose of storage and preservation. Modified atmosphere preservation technology is a technology that prolongs the storage life and shelf life of food by adjusting the ambient gas. The basic principle is: in a certain closed system In the interior, through various adjustment methods, the regulated gas that is different from the normal atmospheric components can be obtained, and the physiological and biochemical processes and microbial activities that lead to food spoilage can be inhibited. The use of controlled atmosphere to store fruits in cold storage can help ensure the quality of fruits. , and can adjust production and sales, and balance t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the current balance bag of the controlled atmosphere storage is directly connected with the pipeline installed on the controlled atmosphere storage, so when the pressure in the controlled atmosphere storage changes, the pressure It directly acts on the balance bag without buffering, so it will lead to the problem of low service life of the bag body, and once the balance bag has a problem during the storage of pomegranates in the controlled atmosphere warehouse, it may cause improper storage of the pomegranates in the whole warehouse, resulting in poor freshness preservation effect
