        Many people like to use dry lemon bubble water, simple and convenient, and let the water is full of taste. Someone doubt, dry lemon bubble water, are rich in vitamin C and fresh lemon? 
 
        Lemon is the earliest humans found fruits rich in vitamin C, vitamin C content of fresh lemon is 22 mg / 100 grams. So, after dry lemon? 
 
        Vitamin C is a kind of higher antioxidant activity, light and heat will cause damage to it, so in the process of dehydration, high temperature and freezing of vitamin C caused serious damage. In addition, vitamin C is a water-soluble vitamin, the presence of water environment easily, when after losing water exposed in the air of oxygen rich, are easy to be accelerated oxidative damage. 
 
        From which we can see that dry lemon after dehydration processing, and exposed to the air for long, the vitamin C content is almost zero, so to speak. With dry lemon bubble water, which exist in the sour taste comes from the lemon citric acid, and vitamin C does not exist. 
 
        Therefore, if the trouble, the use of fresh lemon slices bubble water, is a better choice. But it is worth noting that some brewed with warm water, because of the high temperature of water also dropped the vitamin C destruction.
