Is the drum of cold fresh air regulating bag normal?

by admin

cold fresh meat is usually inflated with high oxygen and carbon dioxide. Because cold fresh meat consumes a lot of oxygen, it is inflated to prevent the box from collapsing

there are two aspects that will cause the expansion of modified atmosphere packaging:

1. When I first bought the box, the temperature of the box is relatively low, and the appearance will not change. However, when I put it at room temperature, the gas in the box will expand and contract, which is a common problem of modified atmosphere packaging. In this case, the swelling is relatively mild and can still be eaten

2. And it has gone bad, because most bacteria breathe and produce carbon dioxide and water, making the box bulge. This bulge will bulge in cold storage, and it is even more serious at room temperature. The box is deformed. This is inedible. The bacteria have exceeded the standard and become rotten

there are two aspects that will cause the bulge of modified atmosphere packaging:

1. When I first bought the box, the temperature of the box is relatively low and the appearance will not change, but the principle of thermal expansion and cold contraction of the gas in the box will bulge after being placed at room temperature. This is a common problem of modified atmosphere packaging. In this case, the swelling is relatively mild and can still be eaten

2. In addition, it has gone bad, because most bacteria breathe and produce carbon dioxide and water, making the box bulge. This bulge will bulge in cold storage, and it is even more serious at room temperature. The box is deformed. This is inedible. The bacteria have exceeded the standard and become rotten

Introduction

can be widely used for students The packaging of cooked meat, poultry, fish, fruits and vegetables and other leisure foods or cooked foods such as bread, pastry and boxed rice has been increasingly ignored by food processing manufacturers and consumers because it can better maintain the original taste, color, shape and nutrition of the food and achieve a long preservation period

in the European and American markets, foods with modified atmosphere packaging have developed rapidly, with an annual growth rate of 25%. In the domestic market, there are as many as 5 billion boxes of raw and cooked products with modified atmosphere packaging every year. The annual growth rate is 20%, replacing the shortcomings of traditional food vacuum packaging, such as high temperature, high pressure, sterilization, quality assurance and no fresh preservation

cold and fresh meat is usually inflated with high oxygen and carbon dioxide, because cold and fresh meat consumes a lot of oxygen. In order to prevent the box from collapsing, it is specially inflated

there are two aspects that will cause the modified atmosphere packaging to bulge:
1. When I first bought it, the temperature of the box is relatively low, and the appearance will not change, However, when placed at room temperature, the gas in the box will expand and contract with heat, which is a common problem of modified atmosphere packaging. In this case, the swelling is relatively mild and can still be eaten
2. It has gone bad, because most bacteria breathe and produce carbon dioxide and water, making the box bulge. This bulge will bulge in cold storage, and it is even more serious at room temperature. The box is deformed. This is inedible. The bacteria have exceeded the standard and become rotten.
