It is best to put in the refrigerator for various sauce condiments.
To say what needs to be placed in the refrigerator, we must first start with the role of the refrigerator.
The refrigerator can extend the preservation time of food, in the final analysis, it is a "cold" word.According to the basic principles of chemistry, the speed of chemical reactions will slow if the temperature decreases.For example, the degradation of vitamins, the oxidation of fat, and the decomposition of the flavor substances will be slower at low temperature.Similarly, the growth of microorganisms will also be suppressed due to cold.Generally speaking, most bacteria like to from room temperature to body temperature. At 4 ° C, most bacteria growing speeds are suppressed, so foods are not as easy to corrupt as at room temperature.However, the bacteria will not die in the refrigerator, but the breeding speed is slower.At this time, there are still some cold -resistant bacteria that can grow slowly, and the mold can also move at the temperature of the refrigerator, so steamed buns and bread are still mildew in the refrigerator.At the same time, this is why the food in the refrigerator still needs to be fully heated before eating.

Put honey in honey in the refrigerator will prompt it to crystallize glucose.This change does not affect the safety of honey, nor does it affect its nutritional value, but it will only affect the uniformity of the taste.Some people think that honey is corrupted, throwing away a bottle of honey, and waste food after washing electricity, it is a pity!

Disinfection milk puts the refrigerator for more than 48 hours
When vegetables, especially green leafy vegetables, are stored at room temperature, the nutritional components will gradually lose, and nitrite will increase rapidly (unfortunately, supermarkets usually sell vegetables at room temperature).Okay, the subcontracting is placed in the refrigerated room.Some people first put on a plastic bag with a newspaper bag, which is better moisturizing.
The yogurt is stored at room temperature, and the lactic acid bacteria will die soon (unfortunately! Many supermarkets sell yogurt products at room temperature, especially those who sell at discounted), lose some health care value, and it is easy to taste sour.
Sterilization milk stores bacteria at room temperature and it will exceed the standard quickly; it is also necessary to drink within 48 hours in the refrigerator, and it is better to drink it within a few hours after opening.
Cooked meat products may breed bacteria, or even a variety of dangerous pathogenic bacteria; soy products are more likely to cause a large number of microorganisms than meat products. They are best to put in the depths of the refrigerator to lean on the inner wall, or put them in fresh -keeping preservation.In the box.
All kinds of canned foods, aluminum foil packaging cooked food, tomato sauce, native box milk, pure fruit juice, beverages and other foods are sterilized or sterilized products, and sterilized at the same time are completely sealed.There is no oxygen to run in, so it can be stored at room temperature.However, once it is opened, the bacteria have entered the path again, and the oxygen will not be politely driven in.If you dont finish eating in time, then the rest must be put in the refrigerator.Of course, it is best to pour out part of it after opening.
