Wash the fresh beans, put them into a fresh-keeping bag, and store them in the refrigerator.

Refrigeration is a method of preserving food, but this method does not kill microorganisms, it only inhibits their reproduction. The lower the refrigeration temperature, the longer the food will be preserved. The temperature of the refrigerator is generally controlled between 1-7 degrees, which can prevent food from rotting in a short time.

The lower the temperature in the refrigerator, the slower the growth of microorganisms, and the slower the biochemical reactions that deteriorate the taste, color, texture and nutritional content of food. It is very important that food is not contaminated by knives before being refrigerated.
