保鮮袋區(qū)別是什么，裝菜應該怎么選？

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

塑料袋是我們基本上每天都會接觸到的，那你每次買完菜或者剩菜是用塑料袋就直接裝了放進冰箱嗎？為什么看上去同樣是塑料，保鮮袋就更加適合裝食物放進冰箱。

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.

市面上所售的保鮮袋有聚乙烯（PE）、聚氯乙烯（PVC）、聚偏二氯乙烯（PVDC）三種。

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

其中PE和PVDC相對，前者一般用于果蔬包裝，后者則多用于熟食、火腿包裝。PVC成分的保鮮袋，一般用于食品蔬菜的外包裝，也就是我們平常在外面使用的塑料袋，對身體可能會帶來一些潛在的危害。這類塑料袋不透氣，直接裝果蔬食物容易導致蔬果缺氧，會加速蔬果腐敗的速度。

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.

而正規(guī)合格的保鮮袋，具有很強的透氣性，包裹住食物后氧氣也可以正常流通，可物質食物上的厭氧菌繁殖，起到保鮮作用。

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.

那關于塑料袋有害健康的傳言是否又真實？

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

塑料袋只要符合相關規(guī)定的話，不論是常溫下還是冷藏環(huán)境下使用，都是有保障的，無需過多擔心。

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，塑料袋內含有的這兩個物質一般也不會給健康帶來威脅，增塑劑的作用是增加塑料柔韌性、彈性，一般會在100°C以上或碰到油脂后才會遷移，這個過程非常緩慢，即便是遷移了，量也非常少，對健康而言不足為慮。

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，我們日常使用的更多是白色塑料袋。再加上，在低溫環(huán)境下儲存1~2天食物，一般也不會引起苯并芘揮發(fā)有害物質。

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.

曾有技術人員對塑料袋進行過一項實驗，在分別購買了價位不同、原料均為聚乙烯（PE）材質的2種食品級塑料袋以及旁自取的塑料袋。并在內購買了青瓜、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.

隨后將這些蔬菜和塑料袋都送往國聯(lián)質檢食品藥品評估中心，將五種蔬菜分別使用塑料袋裝后放入冰箱內，儲存一周后對蔬菜內的成分進行檢測，結果是五種蔬菜內都沒有檢測出增塑劑。

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.
