食品包裝袋方便袋不能長時間保存水果

來源:http://wujikeji.com/ 日期:2022-05-05

現(xiàn)在方便袋已經(jīng)被使用到了千家萬戶,使用它在保鮮水果也是我們普遍使用的方法,其原理是降低氧的濃度,增加二氧化碳的濃度,使蔬果處于休眠狀態(tài),延長貯存期。通常就是用方便袋把水果包嚴(yán)實。但是并非能無限貯存,時間較長水果照樣爛掉。
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.
方便袋是不宜長時間保鮮水果的,因為蔬菜水果為有*食品,含水分較高,并含有水溶性營養(yǎng)物質(zhì)和酶類。在整個貯存期間仍迸行著很強(qiáng)的呼吸活動。在一般情況下,每上升10攝氏度,呼吸強(qiáng)度就增加一倍,在有氧的條件下,果蔬中的糖類或其他有*物質(zhì)氧化*解,產(chǎn)生二氧化碳和水分,并放出大量熟量;在缺養(yǎng)的條件下,糖類不能氧化,只能分*產(chǎn)生酒精、二氧化碳,并放出少量熱量。
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,二氧化碳濃度不能無限度地上升,只能提高10。氧濃度的下降也不能超過5,否則果疏在缺氧時為了獲得生命活動所需的足夠的能*,就需要*解更多的營養(yǎng)。同時,因缺氧呼吸產(chǎn)生的酒精留在果疏里,會引起果疏腐爛變質(zhì),所以果蔬放方便袋內(nèi)存放時間不宜過長,尤其是有些方便袋質(zhì)量本身還有問題,可能會含有毒*。
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 *.
