紧张的生活中,不少人往往买上够吃几天的新鲜蔬菜,怎奈没几天工夫,这好好的蔬菜就容颜衰老,更重要的是,蔬菜里的营养在不知不觉中流失了。买回家的蔬菜到底怎么保存才能留住它们的营养呢? 专家说:“生命活动的标志就是呼吸,蔬菜采收前呼吸消耗的营养能够通过光合作用来补充,你采收以后,营养物质供给的来源断了,但它还消耗,所以营养就越来越少了。水果也好,蔬菜也好,保存就得控制它呼吸,控制好这种低温、低湿、高氧、高二氧化碳,让它处于半死不活的环境,必须这样做。” 正确的保存方法应该根据蔬菜的不同种类,分门别类保存。比较好保存的蔬菜是果类蔬菜,如西红柿、茄子、青椒、南瓜等等,它们一般是在没有完全成熟的时候被采摘下来的,所以随着酶的作用,有一个后熟的过程,存放它们要先判断成熟度。拿最常吃的西红柿来说,像大部分还发绿的,就可以放在室内 Tense life, many people often buy enough to eat fresh vegetables for a few days, persevering a few days time, this good vegetables on the face of aging, more importantly, nutrition in vegetables lost unconsciously. Experts say: “The hallmark of life activity is breathing. The nutrients consumed by the respiration of vegetables before harvest can be supplemented by photosynthesis. After you harvest, the nutrients you supply The source is broken, but it also consumes less and less nutrition, fruits or vegetables, you have to control it to breathe, to control the low temperature, low humidity, high oxygen, high carbon dioxide, let it In a semi-permanent environment, this must be done. ”The correct method of preservation should be based on different types of vegetables, stored in different categories. Better preserved vegetables are fruits and vegetables, such as tomatoes, eggplant, green peppers, pumpkins, etc., they are generally not fully ripe when picked down, so with the enzyme, there is a process of ripening, storage They must first judge the maturity. Take the most common tomatoes, like most of the green, you can put indoors
