The reason why chrysanthemum turns green when soaked in water

The reason why chrysanthemum turns green when soaked in water may be because the chlorophyll in the chrysanthemum itself is destroyed, or it may be because the merchant has smoked it with drugs, so we should judge the reason why chrysanthemum turns green when soaked in water. If the greening is caused by the presence of anthocyanins in chrysanthemums, it generally does not affect our health. However, chrysanthemum tea made with drug dyes cannot be consumed.

This is a normal phenomenon. The chlorophyll in the chrysanthemum tea has been isolated, and the green color is related to the water temperature and the local water quality. It is normal for chrysanthemum tea to change from white to green. If white chrysanthemums are soaked for a long time, the chlorophyll they contain may be soaked out, causing discoloration. In addition, if chrysanthemum tea is brewed for too long, the chlorogenic acid contained in the tea will oxidize and turn green in the air. This means that the chrysanthemum has changed its nature when it turns green and cannot be drunk. It must be poured out.

Chrysanthemum contains anthocyanins, which can react with acidic or alkaline substances in water to form color. When the pH value of the water is alkaline, the anthocyanins will turn blue-green. It is also related to temperature. The higher the temperature of the brewing water, the faster it turns green. Generally, the above problems will not occur when brewing with purified water, but tap water is slightly alkaline and will turn green after brewing for a long time, but it has no toxic side effects and has nothing to do with the quality of chrysanthemum tea.

The color change of chrysanthemum tea is also related to the variety of chrysanthemum. Generally, Gongju tea will be green even if it is not soaked overnight, but the color of freshly brewed tea is light green, while that of tea left overnight is dark green. When Hangzhou white chrysanthemum, Beijing white chrysanthemum and fetal chrysanthemum are soaked in water, they turn yellow with a hint of sweet fragrance and generally do not turn green even if left overnight. Another possibility is that this chrysanthemum may have been smoked with sulfur dioxide in order to make money, and people will be poisoned if they drink it.

From the above introduction, we can know the main reasons why your chrysanthemum turns green when soaked in water. I hope everyone can judge for themselves why the chrysanthemum turns green. Regarding the practice of soaking chrysanthemum in water, if the water turns green, we can choose not to drink it, or we can find out whether it is caused by chlorophyll.
