Immature lemon contains a lot of limonin, which is higher in citrus fruits, and lemon is the highest one. It will be bitter and astringent when eaten, which will reduce the taste of lemon. Some varieties of lemons contain a lot of this bitter ingredient, so the water will contain bitterness when brewing.
Lemon peel is rich in flavonoids. If it is brewed with boiling water or hot water, it is easy to release bitterness, resulting in a certain bitterness of lemonade and a certain bitterness of lemon seeds. Lemonade is edible when bitter taste is greater than sour taste, and limonin is also beneficial to human body.
Tips for making lemonade
1, it must be light, a large piece of lemon with skin can be soaked in water, and 3~4 small cups can be poured. Such lemonade has no strong sour taste, and can be drunk without sugar or honey, and the energy content is almost negligible.
2, be sure to bring the skin, because lemon peel contains high flavonoids, and lemon essential oil is mainly in the skin.
3, the slice must be thin, otherwise the aroma components in the lemon peel are not easy to soak out.
4, it is best to use warm water to soak, if the water temperature is too low, the fragrance is not easy to soak out.
