现在方便袋已经被使用到了千家万户，使用它在保鲜水果也是我们普遍使用的方法，其原理是降低氧的浓度，增加二氧化碳的浓度，使蔬果处于休眠状态，延长贮存期。通常就是用方便袋把水果包严实。但是并非能无限贮存，时间较长水果照样烂掉。

Now convenience bags have been used in thousands of households. It is also a commonly used method to preserve fruits. Its principle is to reduce the concentration of low oxygen, increase the concentration of carbon dioxide, make vegetables and fruits in a dormant state and prolong the storage period. Usually, the fruit is wrapped tightly in a convenience bag. However, it can not be stored indefinitely. The fruit will rot even after a long time.

方便袋是不宜长时间保鲜水果的，因为蔬菜水果为有*食品，含水分较高，并含有水溶性营养物质和酶类。在整个贮存期间仍迸行着很强的呼吸活动。在一般情况下，每上升10摄氏度，呼吸强度就增加一倍，在有氧的条件下，果蔬中的糖类或其他有*物质氧化*解，产生二氧化碳和水分，并放出大量熟量;在缺养的条件下，糖类不能氧化，只能分*产生酒精、二氧化碳，并放出少量热量。

Convenience bags are not suitable for keeping fruits fresh for a long time, because vegetables and fruits are * foods with high moisture content and contain water-soluble nutrients and enzymes. During the whole storage period, there is still strong respiratory activity. Under normal circumstances, the respiratory intensity will double for every 10 ° C rise. Under aerobic conditions, sugars or other * substances in fruits and vegetables will oxidize and decompose, produce carbon dioxide and water, and release a large amount of maturity; Under the condition of lack of nutrition, sugars can not be oxidized, but can only produce alcohol and carbon dioxide, and release a small amount of heat.

但是，二氧化碳浓度不能无限度地上升，只能提高10。氧浓度的下降也不能超过5，否则果疏在缺氧时为了获得生命活动所需的足够的能*，就需要*解更多的营养。同时，因缺氧呼吸产生的酒精留在果疏里，会引起果疏腐烂变质，所以果蔬放方便袋内存放时间不宜过长，尤其是有些方便袋质量本身还有问题，可能会含有毒*。

However, the concentration of carbon dioxide can not rise indefinitely, but can only increase by 10. The decrease of oxygen concentration should not exceed 5, otherwise Guoshu needs to know more nutrition in order to obtain enough energy for life activities in case of hypoxia. At the same time, the alcohol produced by hypoxia breathing will be left in Guoshu, which will cause Guoshu to rot and deteriorate. Therefore, the storage time of fruits and vegetables in convenience bags should not be too long, especially some convenience bags have problems in quality, which may contain toxic *.
