With the continuous development of society, people's living standards and quality continue to improve, and people's requirements for food are getting higher and higher. In addition to delicious food, they also pay great attention to its nutritional value. Most foods need to be refrigerated in a refrigerator to lock their nutrition.
After years of research and exploration, BESTTOP refrigerator experts pointed out that food preservation must have ecological indicators such as temperature, humidity, wind direction, gaseous state, and antibacterial.
1. Humidity index
Water is a source of fresh fruits and vegetables. When fruits and vegetables are short of water, they will dry up and wither. The refrigerator in the supermarket must maintain a certain humidity so that the fruits and vegetables can be fresh and fresh.
2. Wind direction index
Supermarket refrigerated cabinets should use multi-faceted air supply to achieve 360 ° air supply, so that the temperature in all corners of the supermarket refrigerated cabinet will be more uniform, and the food will not deteriorate due to temperature fluctuations, and the breath will always be kept fresh.
3. Temperature index
Different foods require different storage temperatures. For example, the best storage temperature for milk, beer, fruit juice, jam is 0℃-5℃, so it is suitable to be stored in the refrigerator in the supermarket freezer; the storage temperature of fish, meat, ice cream and other foods should be lower than -6℃, and they should be stored at The freezer compartment of the supermarket refrigerator is the most reasonable.
4. Gaseous index
The ethylene gas released by fruits and vegetables is easy to make food mature; the high oxygen content of supermarket refrigerators is easy to cause food to rot and deteriorate. Therefore, it is necessary to effectively absorb ethylene gas and adjust the air composition reasonably to make fruits and vegetables have a longer shelf life.
5. Antibacterial indicators
If the antibacterial measures of the supermarket refrigerator are not done well, more than 10 kinds of harmful bacteria such as Escherichia coli, mold, and Staphylococcus aureus will breed, multiply, and erode the cytoplasm of the food in the supermarket refrigerator. Not only are they completely deficient in nutrients, but also by toxins. Pollution. Therefore, supermarket refrigerated cabinets must achieve all-round three-dimensional antibacterial to prevent "illness from entering the mouth."
