Vitamin C is a highly active antioxidant, which will be damaged by light and heat. Therefore, during dehydration, high temperature and freezing will cause extremely serious damage to vitamin C in lemon. In addition, vitamin C is a water-soluble vitamin, which is easy to exist in an environment with water. Exposure to oxygen-enriched air after dehydration will be destroyed by accelerated oxidation.

After long-term dehydration and exposure to air, the content of vitamin C in dried lemon is almost zero. So use lemon to soak in water. The sour taste comes from citric acid in lemon, and there is no vitamin C.
