Plants deteriorate mainly because their respiration produces CO? and alcohol. Alcohol poisons plants. In an oxygenated environment, plants' respiration (aerobic) will speed up and they will become more susceptible to deterioration.
Several conditions for aerobic respiration: suitable temperature, O?, water. To weaken aerobic respiration requires low temperature, lack of oxygen, and dryness.
Therefore, using a refrigerator is to keep it at a low temperature to ensure that it will not deteriorate due to respiration.
After vegetables and fruits are picked, their vitamins and other nutrients will be lost over time. If stored in the refrigerator, the activity of bacteria and enzymes will be greatly reduced due to the low temperature. Moreover, at low temperatures, the pores of the plant will shrink and the communication with the air will be reduced. Nutrients are not easily lost. It can achieve the effect of preservation.
Refrigerators are now also divided into household and commercial uses. Commercial refrigerators include vertical multi-door freezers, which are usually used to display bottled beverages such as refrigerated juice sodas. Air curtain cabinets (commonly known as open or open freezers, without doors) are usually used to display refrigerated vegetables, fruits, yogurt, imported beverages and other products that require great attention to their quality. Without doors, customers can check and select, and they also prevent spoilage. question.
Fruits and vegetables are obviously better displayed and refrigerated in air-curtain cabinets.
