1. fruits
Tropical fruit should not be placed on the refrigerator
Banana banana: If placed in 12 degrees centigrade of local storage, will make black rot of banana.
Fresh Lychee: If the Lychee 0 ℃ environment places a day that will make their skin black, pulp turned sour.
Tropical fruit with the fear of low temperatures, is not suitable in the fridge, if refrigerated, it will "frostbite" fruit, so that it appears the epidermal SAG, dark brown spots, not only loss nutrition, but also easy metamorphic.
The immature fruits, it cannot be put into the refrigerator, it will be difficult to properly mature. The correct approach is to avoid light, cool and ventilate during storage.2. vegetables
Frozen vegetable cannot
Tomatoes: tomatoes after freezing, the meat quality is vesicular, seem soft rot, or spallation phenomenon, there are dark spots on the surface, the Cook not cooked, fresh, serious then decay.
Cucumbers, green peppers: cucumber, green peppers stored in the refrigerator for a long time, the frozen "wound" – black, soft, turned sour.
President of hair sticking cucumber also. Because the temperature in the fridge for 4 ℃-General 6 ℃, and cucumber storage temperature is 10 ° c to 12 ° c, the green pepper is 7 ° c to 8 ° c and it would not be appropriate for a long time.Leaf dish: because it is easier to rotten cold storage-it is best not to put next to the refrigerator.
Chinese cabbage, celery, onion, carrot, suitable temperature: 0 ℃.
Cucumbers, eggplant, tomatoes and other suitable temperature:-10 ℃ 7.2 ℃. Pumpkin appropriate at 10 ° c above.III. food class
Bread with ham and deteriorating
Chocolate: put into the fridge out of chocolate in the surface prone to frost, not only lose the original mellow taste, but also conducive to the reproduction of bacteria.
The best temperature for storing chocolate is 5 ° c-18 ° c. Summer room temperature is too high, you can use plastic bags, sealed, and then placed in the refrigerator storage room for storage. Check out, don't immediately open and let it slowly at room temperature to be edible.Ham: If the ham into the refrigerator cold storage, the water will freeze, fat precipitation, ham-caking or loose, meat quality, extremely easy to corruption.
Bread: bread baking process, the flour of starch in the noncyclic Division is aging, and this is the bread and produce flexible and soft structure.
With the extension of the time, bread of amylopectin amylose portion slowly associating the soft bread becomes hard, this phenomenon is called "ripen." "Ripen" speed and temperature. In temperature (freezing point above) aging more rapidly, and the bread on the refrigerator, the hardened degree more quickly.Fish should not be placed too long: refrigerators should not be kept in fish for too long, cold temperature of household refrigerators to-15 ° c in General, the best refrigerators can only reach the-20 ° c, and fishery products, especially fish, the storage temperature is not up to-30 ° c below fish tissue occurs dehydration or other changes, such as frozen carp, long, prone to rancid fish, meat quality changes, inedible.
