Why does lemon peel change color after soaking in water?

Because of soaking, vitamin c is easy to oxidize and turn yellow, especially at high temperature. Nutrients or substances in the skin will dissolve in water, so they will change color.

Because vitamin c is easy to die at high temperature, it can't be soaked in a thermos for a long time, and some toxic substances in plants will be soaked out. Lemon contains a lot of vitamin C, which is easily oxidized. The vitamin C content of dried lemon slices is definitely lower than that of fresh ones.

It is best to use warm water to soak lemons, and lemon slices with skin must be used to soak lemons, because the content of flavonoids and lemon essential oil in lemon peel is higher, which is more drinkable. In addition, in order to facilitate the dissolution of the beneficial components of lemon peel, it must be cut very thin when slicing.
