Perishable food.

They are foods that necessarily have to be refrigerated or frozen for proper preservation in good condition, retarding the growth of microorganisms harmful to health, as are the bacteria and fungi. These generally favor the decomposition of perishable foods, which because they are fresh foods have enzymes that help degradation, thus altering their organoleptic characteristics (flavor, aroma, texture and color).
