Freezers frozen food and the relationship between evaporation

< p > freezers frozen food and the relationship between evaporation is the real purpose of freezers frozen food is slow food evaporation, freezers are low temperature, is to make the items contained in the short of evaporation, and prolong the life span of the items. The air-conditioner in the relationship between food cold storage and evaporation is what? Let the cooler price with case analysis, to explain to everybody. Most fruits and vegetables leaf water transpiration are formed by stomatal emits into the environment; Water with gas, through the surface of the plant body to send out from the body in vitro, formation of evapotranspiration. Contained in fruits and vegetables in a refrigerated cold storage or transport moisture volatilizes, make pure water without any obstacles to be lost, evaporation, evaporation physiology is one of the main content of fruits and vegetables postharvest physiology. So the relationship between evaporation and tightly air-conditioner refrigeration and the food itself. Before because of the food in the commercial freezer refrigeration, fruit general moisture content is 85% ~ 90%, vegetables, water content is 70% ~ 95%. Plants in a series of insect activity on the body of water as a medium, such as nutrient dissolution, absorption, transfer and the effect of various enzymes, respiration and the dissolution of gas in release and so on a series of physiological activity, are to be carried out under the presence of water. If there is no water in fruits and vegetables lose life activities. Of fruits and vegetables after harvest in the process of air-conditioner stored moisture to evaporate, such as not added body moisture loss gradually, cell turgor pressure is reduced, relieve itself quality, make the fruit and vegetable surface produces shrivel, luster fade phenomenon, lead to form wilting. Fruit and vegetable moisture lost 5%, will lose luster and freshness. Fruit loss of appearance of the quality of fresh and tender crisp, full and even normal metabolism is destroyed, will cause the decrease of disease resistance and water resistance. Extensive use of freezers frozen fruits and vegetables in the supermarket, it is through this. < br / > < / p >
