What are the typical features of refrigerated food after the air-conditioner

< p > what are the typical features of food in the commercial freezer refrigeration after put some food in the freezer refrigeration, suddenly will find that there are some changes. Such as watermelon in the summer, after the freezers frozen found sweet all the more. Other fruits, too, why do we feel this way? Let the cooler price to share some knowledge and experience in this field. Many people have found more sweet fruit cold? Why is this? Primarily this is because the sugar in fruit of fructose, there is a cold sweet characteristics: its sweetness and the temperature has a great relationship, the lower the temperature below 40 ℃, the higher the fructose sweetness, maximum of cane sugar, 1. 73 times; Cold sweet reason is fructose has two configurations; α Type and & beta; Type, & alpha; Type a sweetness of fructose & beta; Type 3 times of fructose, when the low temperature part & beta; Type of fructose into & alpha; Type of fructose, and increase the sweetness. Of this feature with fructose, extensive use of Yu Qingliang drinks and other cold food, such as carbonated drinks, juice drinks, sports drinks, ice cream, ice cream, etc. So we will feel very sweet in eating the cold drink. So everyone can see the truth, there are a lot of fruit is also such. So if we know that the air-conditioner refrigeration after the fruit is sweet, so is no problem? Of course not, when we want to put the fruit in the freezer, you also need to pay attention to details. Don't wash the fruit cold front, or in the commercial freezer easy metamorphic rot. Buy fruit don't eat or eat after go home, in the air-conditioner is the best way to save. Before in the freezer, however, be careful not to clean, otherwise easy to rot, and try to finish within a week. Each fruit has the best storage temperature, retention time and put the longer, fruit nutrition and flavor also is bad. Some fruits like banana, pineapple, mango, papaya, lemon, etc. , in fact, as long as the indoor shady corner, unfavorable cold storage for a long time. In addition, apple, pear, peach, banana, papaya or some easy rotten fruit, easy to produce ethylene, had better not put together with other fruit, and so on, these are all we need to pay attention to, or it will easily backfire, not only good refrigeration, instead, to achieve the objective of the opposite. < br / > < / p >
