The food in bulk has sale in every supermarket, food market, the person buying it is in an endless stream too. It is mere that it is cooked but recently in U.S.A. " " the magazine publishes the article to point out, consider in terms of hygiene security and food nutrition, 5 kinds of food had better not buy the one in bulk. As to this, nutrition research room professor Wang DongLan of the military academy of medical sciences says, it is very difficult for people to understand the food in bulk on precise date of production, and the time transported and put on the shelve, so that cause the health problem for oneself, must take care. Especially holding time should not overlong the food, should pay attention to even more. Grain. The grain in bulk is apt to cause germs, and nutrient losses are relatively great. Because the grain contains the moisture, will cause germs to breed as to the moist environment. It is a kind of carcinogen to be the most harmful for human body among them - --Yellow aspergillus toxin. In the grain, can't it buys a in bulk one to be brown rice most, it though nutritious, but quality guarantee period is very short, it is only half a year since usually. Especially the one among them links A and and links C, will be totally oxidized when standing in the air for about 3 months, the efficiency of health care will be lost. Edible oil. The edible oil in bulk does not mostly have a packing mark, have no name and address of factory, do not have date of production, quality guarantee period, there is no quality criteria " There is not three " Products, there are serious hygiene hidden dangers, must not buy. Especially it is more intolerable to at one time buy a large amount of edible oil. This is because first, the oil uncapping will usually be saved in the kitchen, the high, humidity of the temperature is large, it is apt to cause bacteria; Second, the oil in the oil is extremely apt to oxidize the acid to frustrate, will increase the carcinogenic risk. So DongLan Wang propose edible oil should buy inner wrapping, uncap in 3 months eating up. Meanwhile, need to remind. The holding time of the edible oil is still involved in kind of the oil. For example olive oil can only be saved for 6 months, can only be kept for 3 months after the peanut oil Kaifeng. Nut. The nut is large, very apt to be rotten because of the oil content. The nut in bulk keeps in touch with the air directly, not merely will accelerate its going bad, the mineral nutrient included, if calcium, zinc, iron are easier to run off. So in bulk to usually have one or two months only quality guarantee period in nut. Had better buy the inner wrapping that can be eaten up in short term when buying nuts. Frozen food. Don't think, freeze food, can keep for a long time unscrupulously, its pot-life had only a few months in fact. How long frozen food various in style in ice box in the supermarket, have spent in transporting and storing, not easy to judge. So, the work is too more busily to let instant frozen dumpling, frozen meat,etc. take the refrigerator freezer either, the frozen food had better be bought and eaten now now too. Condiment product. No matter in bulk Chinese prickly ash, diligent and right, or bottled chilli sauce, about taste will turn light half a year generally, flavour ability to weaken, and very apt to cause bacteria, endanger the health greatly. Flavoring agent must be bought fewer but betterly, had better not buy big bottle in bulk. (Bao Jie)
