Limonin. The reason why green lemons are bitter in water is that green lemons contain a lot of limonin, which is soluble in water, and the wrong brewing method also leads to bitter taste of green lemons in water.

Limonin mostly exists in orange fruits, and lemon is one of the fruits with the highest content. In addition, there are more limonin in green lemon peel and green lemon seeds, so as long as the green lemon is not treated well, it is easy to cause bitter taste.
