保鲜袋区别是什么，装菜应该怎么选？

What is the difference between the fresh-keeping bags and how to choose the vegetables?

塑料袋是我们基本上每天都会接触到的，那你每次买完菜或者剩菜是用塑料袋就直接装了放进冰箱吗？为什么看上去同样是塑料，保鲜袋就更加适合装食物放进冰箱。

Plastic bags are basically something we come into contact with every day. Do you use plastic bags to store food or leftovers directly into the refrigerator after you buy them? Why does it look like plastic? The fresh-keeping bag is more suitable for putting food in the refrigerator.

市面上所售的保鲜袋有聚乙烯（PE）、聚氯乙烯（PVC）、聚偏二氯乙烯（PVDC）三种。

The fresh-keeping bags sold on the market are polyethylene (PE), polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC).

其中PE和PVDC相对，前者一般用于果蔬包装，后者则多用于熟食、火腿包装。PVC成分的保鲜袋，一般用于食品蔬菜的外包装，也就是我们平常在外面使用的塑料袋，对身体可能会带来一些潜在的危害。这类塑料袋不透气，直接装果蔬食物容易导致蔬果缺氧，会加速蔬果腐败的速度。

PE and PVDC are relatively safe. The former is generally used for fruit and vegetable packaging, while the latter is mostly used for cooked food and ham packaging. PVC fresh-keeping bags are generally used for the outer packaging of food and vegetables, that is, the plastic bags we usually use outside, which may bring some potential harm to the body. This kind of plastic bag is airtight, and it is easy to cause anoxia of fruits and vegetables when directly containing fruits and vegetables, which will accelerate the speed of corruption of fruits and vegetables.

而正规合格的保鲜袋，具有很强的透气性，包裹住食物后氧气也可以正常流通，可物质食物上的厌氧菌繁殖，起到保鲜作用。

The regular and qualified fresh-keeping bags have strong air permeability, and the oxygen can also circulate normally after wrapping the food, which can reproduce anaerobic bacteria on the material food and play a role in fresh-keeping.

那关于塑料袋有害健康的传言是否又真实？

Is the rumor that plastic bags are harmful to health true?

塑料袋只要符合相关规定的话，不论是常温下还是冷藏环境下使用，都是有保障的，无需过多担心。

As long as the plastic bag complies with the relevant national regulations, it is safe to use it at room temperature or in cold storage environment, so there is no need to worry too much.

再加上，塑料袋内含有的这两个物质一般也不会给健康带来威胁，增塑剂的作用是增加塑料柔韧性、弹性，一般会在100°C以上或碰到油脂后才会迁移，这个过程非常缓慢，即便是迁移了，量也非常少，对健康而言不足为虑。

In addition, the two substances contained in the plastic bag generally do not pose a threat to health. The role of the plasticizer is to increase the flexibility and elasticity of the plastic. It generally migrates at 100 ° C or above or after touching the oil. This process is very slow. Even if it migrates, the amount is not very small, which is not a concern for health.

而苯并芘一般存在于彩色塑料上，我们日常使用的更多是白色塑料袋。再加上，在低温环境下储存1~2天食物，一般也不会引起苯并芘挥发有害物质。

Benzo (a) pyrene generally exists in colored plastics, and we usually use white plastic bags. In addition, food stored for 1-2 days under low temperature environment will not cause benzopyrene volatilization.

曾有技术人员对塑料袋进行过一项实验，在分别购买了价位不同、原料均为聚乙烯（PE）材质的2种食品级塑料袋以及旁自取的塑料袋。并在内购买了青瓜、娃娃菜、青椒、花菜和青菜。

A technician once carried out an experiment on plastic bags, and bought two kinds of food grade plastic bags with different prices and raw materials of polyethylene (PE) in the supermarket and plastic bags taken by the supermarket. We also bought cucumbers, baby vegetables, green peppers, cauliflower and green vegetables in the supermarket.

随后将这些蔬菜和塑料袋都送往国联质检食品药品评估中心，将五种蔬菜分别使用塑料袋装后放入冰箱内，储存一周后对蔬菜内的成分进行检测，结果是五种蔬菜内都没有检测出增塑剂。

Later, these vegetables and plastic bags were sent to the Food and Drug Safety Assessment Center of the League of Nations, where five kinds of vegetables were packed in plastic bags and put into the refrigerator. After one week of storage, the ingredients in the vegetables were tested, and the results showed that no plasticizer was detected in the five vegetables.
