How to choose
● Choose less tannic acid: The tannic acid content of different varieties of persimmon varies greatly, ranging from 4% to 0.4%. The premise that eating persimmons causes physical discomfort is to eat many persimmons with more tannins. Therefore, the key is to buy less tannic acid. The easiest way to judge whether there is much tannic acid in persimmon is to taste it. The astringent persimmon is, the higher the tannin content is.
● Buy ripe persimmons: When the persimmons are immature, the tannic acid content is high, especially the skin of the pulp, which is close to the persimmon skin. Persimmons in the market can be divided into astringent and sweet types: sweet persimmons can naturally remove astringency on trees before maturity, such as edible crispy persimmons; After picking astringent persimmons, they need to be astringent to remove excess tannic acid, which is suitable for sale and eating, such as the kind that needs to be softened after buying.
Matters needing attention
Low consumption, no more than 1 ~ 2 persimmons per day (about 150 ~ 200g/ persimmon);
● Don't eat persimmons without astringency at will, such as persimmons planted on the roadside or at home, persimmons with heavy astringency and high tannic acid content, which may easily cause gastrointestinal adverse reactions;
● Do not eat immature persimmons;
● People with diabetes should be careful to eat persimmons. Persimmons have high sugar content, close to 20%, mostly simple disaccharides and monosaccharides. Mature persimmons are soft and rotten and can be swallowed without full chewing, so they have a high response to raising blood sugar.
● If you feel strongly unwell after eating persimmon, you should seek medical advice promptly.

L choose crisp and sweet: try to choose eight ripe dates to taste. If the taste is crisp and sweet, it can be judged as a better variety. If fresh dates are not sweet or astringent, they can be defined as raw dates. Fresh jujube with bitter taste, lack of water or soft feeling is inferior jujube.

The more lines, the better the taste. But the elderly who like to eat "noodles" and "rustling" apples can choose red apples. You can also gently press the apple. If it is easy to press, it means that the apple is sweet, otherwise it is a little sour. You can measure the weight of apples by hand. If it is light, it means that it is a cotton apple, while the heavy one contains more water and is a crisp apple. You can also choose apples with more hemp spots, which are generally sweeter;
I choose fresh apples: smell them with my nose first. Fresh apples have a strong fragrance and smell good. If they are kept for a long time, their taste will fade. Secondly, whether an apple is fresh or not depends on its stalk, which is also known as the "apple handle". If it is green, it is an apple that has just been picked; If it is yellow, it means that it has been put for a while and is not fresh enough; If it's black, it means it's not fresh.
