一、包装袋为何会充满气体?
1、 Why is the packaging bag filled with gas?
一方面,包装袋内的气体可以起到保护食品的作用,防止食品在运输和储存过程中被压碎或挤压变形;另一方面,包装袋内的气体还可以保持食品的新鲜度,防止食品因为氧化而变质。
On the one hand, the gas inside the packaging bag can play a protective role in food, preventing food from being crushed or deformed during transportation and storage; On the other hand, the gas inside the packaging bag can also maintain the freshness of food and prevent it from spoiling due to oxidation.
二、包装袋漏气会对食品造成影响吗?
2、 Will air leakage from packaging bags have an impact on food safety?
当我们打开食品包装袋,突然发现包装袋没有充满气体,或者听到了漏气的声音时,我们可能会担心食品的问题。包装袋漏气并不会对食品的造成重大影响。食品包装袋漏气并不代表食品已经变质或不新鲜,只是包装袋内的气体流失了一部分。大部分食品包装袋内的气体是由一些惰性气体组成的,例如氮气和二氧化碳,这些气体对人体并无直接伤害。
When we open a food packaging bag and suddenly find that the bag is not filled with gas, or hear a sound of air leakage, we may be concerned about food safety issues. Leakage of packaging bags does not have a significant impact on food. Air leakage in food packaging bags does not mean that the food has deteriorated or is not fresh, but rather that a portion of the gas inside the packaging bag has been lost. Most of the gases inside food packaging bags are composed of inert gases, such as nitrogen and carbon dioxide, which do not directly harm the human body.
三、包装袋漏气后的保鲜方法
3、 Preservation methods for packaging bags after air leakage
虽然包装袋漏气并不会对食品造成影响,但是对于一些需要保持脆爽口感的食品来说,漏气可能会导致食品变得不再酥脆。针对这种情况,我们可以采取一些保鲜方法来延长食品的新鲜度。可以将食品转移到密封性好的容器中,避免进一步与空气接触;或者可以将食品放入冰箱冷藏,降低食品的温度,减缓食品变质的速度。
Although air leakage from packaging bags does not affect food , for some foods that need to maintain a crispy taste, air leakage may cause the food to become less crispy. In response to this situation, we can adopt some preservation methods to extend the freshness of the food. Food can be transferred to tightly sealed containers to avoid further contact with air; Alternatively, food can be refrigerated in the refrigerator to lower its temperature and slow down the rate of spoilage.
