9.用什么方法脱除贮藏环境中的乙烯? 乙烯是蔬菜本身产生的一种量很少的气体,常以百万分之几的浓度计算,写作ppm。贮藏环境中有很低浓度(如0.1ppm)的乙烯,对蔬菜有催熟作用,促使蔬菜很快衰老,贮藏期大大缩短。为延长蔬菜藏寿命,必须脱除环境中的乙烯,常用的普通方法是高锰酸钾。以分子筛、蛭石、珍珠岩、泡沫砖、硅藻土、氧化铝等疏松物质作载体,吸收饱和高锰酸钾溶液,制成乙烯吸收剂,根据贮量按一定比例放入贮藏封闭系统内,可有效地使乙烯氧化失去活性,然而它又可以
9. What method to remove ethylene in storage environment? Ethylene is a vegetable produced a small amount of gas, often in parts per million concentration, writing ppm. Low concentrations (eg 0.1 ppm) of ethylene in the storage environment have a ripening effect on the vegetables, causing the vegetables to age quickly and the storage period is greatly shortened. In order to extend the life of vegetable hides, the ethylene in the environment must be removed. Commonly used common method is potassium permanganate. With molecular sieve, vermiculite, perlite, foam brick, diatomite, alumina and other loose material as a carrier, absorbing saturated potassium permanganate solution, made of ethylene absorbent, according to the storage capacity by a certain percentage of storage closed system , Can effectively deactivate the oxidation of ethylene, however it is okay
