Why does a refrigerator delay food spoilage?

Keeping food in the refrigerator can delay the reproduction and growth of bacteria, thus prolonging the preservation time of the food, so that the food will not spoil too quickly Because the spoilage of food is a direct consequence of the proliferation of bacteria in the food.

Food that is not put in the refrigerator is particularly prone to spoilage due to high outside temperature, rapid bacterial multiplication, and food. Eating spoiled food can cause a large number of bacteria and their toxins to enter the body, which can easily cause gastrointestinal diseases.

Under the right conditions, a single bacterium can produce 16 million bacteria after 8 hours of continuous reproduction. The suitable reproduction temperature of most bacteria is about 37 °C, below 10 °C, and most bacteria reproduce slowly. Therefore, food stored in the refrigerator can delay the growth of bacteria

Food spoils because of the presence of bacteria, which are most likely to survive in warm and humid conditions. The low temperature in the refrigerator can effectively inhibit the reproduction of bacteria, so as to achieve the purpose of preservation.

The low temperature in the refrigerator inhibits the respiration of bacteria in the food, delays the time of food deterioration, and achieves the preservation effect.

The low temperature in the refrigerator inhibits the respiration of bacteria in the food, and the hotter the temperature, the easier it is for bacteria to multiply.

The lower the temperature in the refrigerator, the less respiration, and the low temperature, bacteria and viruses are not easy to survive.

Low temperatures slow down physical respiration or make it difficult for microorganisms to live at low temperatures.

1. The temperature of the freezer compartment of the commonly used refrigerator is usually at the mercy of minus 10 degrees, which is not able to kill harmful bacteria, but only plays an effect of pressing the growth rate of bacteria, so the food in the refrigerator should be eaten as soon as possible.

2. The freezer is different from the food, and the retention time is also different, fish, shrimp and seafood and other aquatic products contain unsaturated fatty acids that are easy to oxidize, and a hydrogen sulfide substance will occur after oxidation, which has a negative impact on our central nervous system. Therefore, this kind of food must only be stored for a short time, and it is best to eat it within 10 days.
