脱氧剂为了延长食品的保质期,现在有不少食品都采用真空包装。不过,真空包装需要一定的设备。其实,在食品中放一包脱氧剂,也可有效除去部分氧气,使食品较长时间保鲜,故脱氧剂也被称作“保鲜剂”。脱氧剂的种类较多,今天我带来了一些月饼包装中的脱氧剂。据资料介绍,这种脱氧剂的主要成分是铁粉、炭粉和食盐。大家一起想想办法,看看能否将这三种物质分离开来,并通过实验进行验证呢? Deoxidizer In order to extend the shelf life of food, there are many foods are used vacuum packaging. However, vacuum packaging requires certain equipment. In fact, put a pack of deoxidizer in the food, but also can effectively remove part of the oxygen, so that food for a long time fresh, so deoxidizer is also called “preservative.” There are many types of deoxidizer, and today I brought some deoxidizer in moon cake packaging. According to information, the main component of this deoxidizer is iron powder, carbon powder and salt. We think of ways to see if we can separate these three substances, and through experiments to verify it?
