PE保鲜膜使用容易忽略的问题
Easy to ignore problems in the use of PE preservative film
1.PE保鲜膜禁止带着加热食品
1.PE preservative film prohibits the heating of food
PE保鲜膜成分中含有邻苯二甲酸盐和DEHA 等化学物质，大家使用中尤其是微波炉加热后会产生致癌物。建议大家食物有保鲜膜包装时，尽可能不要用微波炉烹调或在蒸笼、电饭锅中加热;尽管不会接触到，建议大家好去除保鲜膜。大家平时保存食品，好用有盖瓷碗盘或不锈钢容器。如果条件允许的话大家在买肉时，可以用自备纸来包肉。食物装在无盖的陶瓷碗内，如果上面附盖保鲜膜，不要装满以免碰到食物。
PE preservative film contains chemical substances such as phthalate two formate and DEHA, which can produce carcinogens, especially in microwave oven. I suggest that when you have food wrap, do not use microwave oven to cook or heat in a steamer or electric rice cooker as far as possible. Though you will not touch it, we recommend that you remove the fresh-keeping film. We usually save food, good cover bowl disc or stainless steel container. If the conditions allow you to buy meat, you can wrap the meat with your own paper. The food is packed in a non - covered ceramic bowl. If it is covered with a plastic film, do not fill it up to avoid food.
2.PE保鲜膜并不是所有事物都适合使用
2.PE preservative film is not all suitable for use
大家应该知道水分比较大的蔬果适合用保鲜膜；如苹果、梨、油菜、韭黄等。这些蔬果使用保鲜膜，不但能够延长保鲜时间，还会增加其中的某些营养素。
Everyone should know more suitable for water Vegetable & Fruit clingfilms; such as apple, pear, rape, leek etc.. These fruits and vegetables use fresh-keeping film, not only can extend the preservation time, but also increase some of the nutrients.
但是萝卜、黄瓜、豆角的好是不使用PE保鲜膜，因为大约是100克裹上保鲜膜的萝卜放置一天后，含有的维生素C含量会明显减少了3.4毫克，豆角减少3.8毫克，黄瓜存放一天一夜后，其维生素C的损失量相当于5个苹果。
But carrots, cucumbers and beans is good without the use of PE cling film, because about 100 grams wrapped in plastic wrap turnip placed a day later, will contain the content of vitamin C was significantly reduced by 3.4 mg, 3.8 mg of cucumber beans reduced, stored for one day and one night after the vitamin C loss equivalent to 5 an apple.
