Does the milk destroy nutrition after heating?
As everyone knows, drink to a cup of warm milk, the result of helpful sleep, so a lot of people before sleeping, especially the elderly are all used to boiling and drinking the milk bought back again. The middle and southern university refined professor of hospital nutriology dept. Li HuiMing in Hunan reminds, this kind of method is inadvisable.
At present, milk sold on the market is all that have already crossed and heated and sterilized the products dealt with. If boiling is in order to be sterilized, does not totally have this necessity. Moreover, the milk is expected much to the disinfecting temperature, takes 3 minutes at 70 , it takes 6 minutes at 60 . Generally speaking, the ultra-temperature can be drunk directly while sterilizing the milk, as to from the milk of freshness that is taken out in the refrigerator, because is cooler, just heat to the temperature suitable to drink.If boil the milk, the temperature reaches 100 , lactose in the milk may present the coking phenomenon, the caramel appears, influence milk mouthfeel and nutrition. In addition, after milk boiling, calcium among them will present phosphoric acid and precipitate the phenomenon, will reduce the nutritive value of the milk too. "It is heating to heat the best way for the milk through water, put the fresh bagged milk into about 5 minutes in the hot water. If choose to boil the milk with milk pan, had better not be leaving all the time, because after the milk is being generally heated to certain temperature, very easy to overflow. " Li HuiMing says.
Need to remind, in order to save time, a lot of people choose to heat with microwave oven, the the intersection of heating and method will present the intersection of temperature and uneven phenomenon, it contains the intersection of polyethylene and composition to be bagged, box install the milk fit for microwave to heat, otherwise know overheat to decompose. So, heat wanting before this first see the explanation that packs going clearly. In addition, set for time should not too long either, ml of the intersection of heating and 1 minutes, too can destroy nutrition.
