Question

薯片等易碎食品宜采用充气袋包装 下列气体中最不适宜充入的是( ) A、N2 B、O2 C、CO2 D、空气

Answer 1

选B
氧气会加速食品氧化变质，最不适宜
氮气和二氧化碳都是常用的包装充气，不与食品反应且无毒
空气虽然也可以使食品氧化，但是氧化的速度比纯氧气慢，虽然空气也不太适宜，但最不适宜的还是氧气

Answer 2

D吧。我也不是很清楚B和D选择哪个，但是我比较倾向于D。因为薯片这类食物大部分应该密封保存，隔绝的是使它变软的物质。空气中有少量的水蒸气，水蒸气是使薯片变软的主要原因，空气中也含有O2，但是量少，70%是N2，而O2的话主要是氧化，它对于薯片的作用我也不是很清楚。这选择题我选择D，但是我不清楚B的原因，抱歉了，知识有限啊。希望下面的人能给点解释。
