After harvesting, astringent persimmons are generally treated with astringency before they can be eaten fresh. Commercial astringent methods mainly include warm water astringency, CO2 astringency, alcohol astringency and ethephon astringency.

Matters needing attention in eating persimmons

1, don't eat persimmons on an empty stomach.

Because persimmon contains more tannic acid and pectin, it will form lumps of different sizes under the action of gastric acid on an empty stomach. If these masses can't reach the small intestine through pylorus, they will stay in the stomach and form gastric persimmon stones.

2. Don't eat 200 grams at a time.

Tannic acid in persimmon can form compounds that the human body can't absorb with minerals such as calcium, zinc, magnesium and iron in food, so these nutrients can't be utilized, so eating more persimmons can easily lead to the lack of these minerals.

Step 3 rinse your mouth after eating

Persimmons are rich in sugar and pectin. After eating persimmons, there is always a part left in the mouth, especially in the teeth. Tannic acid with weak acid is easy to corrode teeth and form dental caries.
