   北京赛车    行业常识    浅谈食品保鲜膜的选购技巧
用微波炉加热食品时,要选用带有"微波炉专用"的包装容器。冰箱里的冷藏、冷冻食品应使用保鲜膜,而不要用普通的塑料袋代替。保鲜膜的特殊工艺和原料具备良好的透气和保鲜性能,而普通塑料袋使用时间稍长就会使食物变质、腐烂,达不到保鲜的目的。
With the microwave food, want to choose a special "microwave" packaging container. Cold storage, frozen food in the refrigerator should use plastic wrap, and don't use ordinary instead of plastic bags. Cling film special process and raw material has good air permeability and preservation performance, and the ordinary plastic bag use time is a bit long makes food spoilage, decay, and reach the purpose of keeping fresh.
用塑料袋包装熟食、点心等直接食用的食物时,最好不要用有颜色的塑料袋。因为这种塑料袋不少是用回收的废旧塑料制品重新加工而成,不能直接装食品。
Packed in plastic bags cooked food, the direct edible food such as dim sum, it is best not to use colored plastic bags. Because of this many plastic bags are recycled waste plastics processing and become, again can't directly food.
注意产品标示的材质:聚乙烯膜(PE膜)现在广泛用于食品的包装;聚丙烯膜(PP膜)透明度高,主要用于面包、小食品等的包装;氯乙烯膜(PVC膜)也可以用于蔬菜、水果等易腐食品的包装,但不可用于油脂性食物的包装,也不能用于微波炉中加热。
Pay attention to product labeling material: polyethylene (PE film) is now widely used in food packaging; High transparency, polypropylene film (PP film) is mainly used in bread, small food packaging; Vinyl chloride film (PVC film) can also be used for vegetables, fruits and other perishable food packaging, but not the packing for greasy food, cannot be used in the microwave heating.
