Cooled meat fresh-keeping storage method and electrostatic field fresh-keeping device used for keeping fresh

Abstract

The invention discloses a cooled meat fresh-keeping storage method and an electrostatic field fresh-keeping device for keeping fresh. The method comprises the following step of combining an electrostatic field fresh-keeping method and high-oxygen modified atmosphere packaging to carry out fresh-keeping storage on cooled meat, and further comprises the following steps: carrying out the high-oxygen modified atmosphere packaging on the cooled meat by adopting a high-barrier-property packaging material; and carrying out the fresh-keeping storage on the cooled meat subjected to the high-oxygen modified atmosphere packaging in a sealed low-temperature environment provided with the electrostatic field fresh-keeping device. The electrostatic field fresh-keeping device comprises a sealed box body or wall body and an electrostatic field generation device, wherein the electrostatic field generation device comprises an electrostatic field generation device body and electrodes; the electrodes are arranged in the sealed shell and are fixed on an inner wall of the sealed box body or wall body through an insulating material; the electrostatic field generation device body is arranged at the outer part of the sealed box body or wall body; the electrodes are electrically connected with the electrostatic field generation device body so that a space electrostatic field is formed in the sealed box body or wall body; and more than one electrode is arranged and the electrodes are distributed at different positions of the space in the sealed box body or wall body.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping and storage of food, in particular to a fresh-keeping and storage method for chilled meat and an electrostatic field fresh-keeping device for fresh-keeping. Background technique [0002] With the improvement of people's living standards and the change of consumer demand for healthy and delicious food, chilled meat is more and more popular among consumers, which is the development direction of fresh meat consumption in my country. However, the divided chilled meat has problems such as short shelf life and surface browning, which cannot fully meet the needs of market circulation, which restricts the promotion of chilled meat in my country. Therefore, prolonging the shelf life of chilled meat and the stability of color and luster and quality are very important to accelerate the development of chilled meat. [0003] At present, the common packaging forms of chilled meat include ordinary tray pa...

Problems solved by technology

In the existing electrostatic field fresh-keeping device, the refrigerator partition is often connected with the electrodes, and then the preserved items are placed on the refrigerator partition, or directly placed on the insulating electrode plate. The preserved items need to be directly connected to the electrode plate. Only contact can keep fresh, and the voltage and current generally used are relatively high, which has great potential safety hazards
