一、包裝袋為何會充滿氣體?
1、 Why is the packaging bag filled with gas?
一方面,包裝袋內(nèi)的氣體可以起到保護(hù)食品的作用,防止食品在運輸和儲存過程中被壓碎或擠壓變形;另一方面,包裝袋內(nèi)的氣體還可以保持食品的新鮮度,防止食品因為氧化而變質(zhì)。
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、包裝袋漏氣會對食品造成影響嗎?
2、 Will air leakage from packaging bags have an impact on food safety?
當(dāng)我們打開食品包裝袋,突然發(fā)現(xiàn)包裝袋沒有充滿氣體,或者聽到了漏氣的聲音時,我們可能會擔(dān)心食品的問題。包裝袋漏氣并不會對食品的造成重大影響。食品包裝袋漏氣并不代表食品已經(jīng)變質(zhì)或不新鮮,只是包裝袋內(nèi)的氣體流失了一部分。大部分食品包裝袋內(nèi)的氣體是由一些惰性氣體組成的,例如氮氣和二氧化碳,這些氣體對人體并無直接傷害。
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、包裝袋漏氣后的保鮮方法
3、 Preservation methods for packaging bags after air leakage
雖然包裝袋漏氣并不會對食品造成影響,但是對于一些需要保持脆爽口感的食品來說,漏氣可能會導(dǎo)致食品變得不再酥脆。針對這種情況,我們可以采取一些保鮮方法來延長食品的新鮮度??梢詫⑹称忿D(zhuǎn)移到密封性好的容器中,避免進(jìn)一步與空氣接觸;或者可以將食品放入冰箱冷藏,降低食品的溫度,減緩食品變質(zhì)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.
