The external temperature is higher and the opening frequency of refrigerator increases, so the inner temperature could not be maintained well and the bacterial breed rate increases. The average temperature in the fridge freezer is 0 ? to 7 ?, which has obvious inhibition function on the regeneration of most bacteria. It could put off the food deterioration time instead of killing bacteria. A part of the bacteria such as e. coli, typhoid bacillus and staphylococcus aureus are still active in the refrigerator, and they continue to multiply and accelerate the food deterioration. In addition, the raw food will also continue metabolism and produce toxic metabolites after placing in refrigerator. Different foods should be placed in different temperature. Meat such as pork and beef should be kept in -18 ? environment and they could only last one week in -2 ? to 5 ?. Green vegetables should be preserved in low temperature which is no less than 0 ?: cabbage, onion, carrot, and celery are suitable for 0 ? temperature; cucumber, eggplant and potatoes are suitable for 7 ? to 10 ?; the temperature of the banana is about 13 ?; apple’s storage temperature is 1 ? to 4 ?.
