Because frozen food has a shelf life, the length of the period depends on the type of food, pre-freezing treatment and freezer temperature conditions.
Buying a refrigerator should figure out the refrigeration performance, freezer temperature is best to reach -18 ℃ below. Some products today can reach minus 20 ℃ - minus 23 ℃, more conducive to prolong the preservation period. In addition to being cold enough, it is also quite important to maintain temperature stability, as fluctuations in temperature can cause cells to break down, resulting in nutrient loss. Therefore access to food should be as fast as possible, a take, reduce the time and number of refrigerator door, and pay attention to not frequent power outages; processed food must be cooled and then frozen; thawed food is best not to freeze again.
