The selection method is as follows: the selected oranges must be ripe oranges, and the immature oranges are not dried tangerines but green tangerines. Also pay attention to the use of orange varieties with thin skin. If the skin is too thick, it is easy to get moldy if it is not exposed to the sun.
1, choose ripe orange peel.
Ripe oranges are ripe oranges, which are sweeter to eat. This kind of orange peel is made of dried tangerine peel.
If you use the skin of an orange that is very sour and not mature, it will be green peel. In traditional Chinese medicine, the efficacy of tangerine peel and green tangerine peel is very different. So be sure to choose ripe oranges.
2. Thin orange peel
The orange peel is too thick to be dried, and it may be moldy before it is dried. So you can try to choose a thinner orange peel.
3. Dry in the sun for a long time
Generally, the dried tangerine peel made in Chinese medicine is very dry, because the dried tangerine peel in Chinese medicine emphasizes that the older the better. If you want to age, you need to leave it. Only after the system is very dry can you leave it for a longer time, so you must be extremely dry.
