Can you really not share delicious and safely with persimmons
Listen to what experts say
Persimmons can grow in most parts of our country, and there are more than a thousand varieties.
In terms of output, Guangxi, Hebei, Henan and Shaanxi are the four main production areas, accounting for more than 60% of the national persimmon production. Most of the persimmons in Guangxi are crisp persimmons , which are sweet, delicious, crisp and chewy. Shaanxi persimmons are brightly colored, thin as paper, plump and juicy. The Hebei persimmon is like a millstone, "as big as a fist, sweet as honey", and has the reputation of "color is better than gold, sweet than jade liquid".
Four tricks to choose persimmons
Member of the Youth Committee of the Chinese Society of Food Science and Technology, Associate Professor of the School of Food Science and Technology, Hebei Agricultural University, and Ph.D. in Food Science, Gao Jie reminds consumers to pay attention to the following four points:
01Look at
00Pick persimmons with full fruits, regular body shape, complete fruit stems, golden or orange yellow persimmons. There are exceptions to the rule of skin color. For example, some naturally deaf-free varieties such as crispy sweet persimmons. Although the skin is blue, it tastes crispy and sweet after peeling.
02smill
Choose persimmons that have natural fruity fragrance, sweet or tastelessness. If you smell alcohol, moldy, and sour smell, the persimmon may have spoiled and spoiled.
03 Touch
The skin of ripe persimmons is softer. If they feel harder to the touch, it means they are not mature. Of course, there are varieties such as crispy persimmons.
In addition to eating fresh persimmons, they can also evaporate the water by drying and other methods to make persimmon cakes. There is a layer of white frost outside the persimmon cake, called persimmon frost. It is a "microcrystalline polymer" formed by condensed on the surface of persimmons during water evaporation. Its main components are fructose , glucose , etc. If the surface of the persimmon cake is very white and falls off after shaking, it is very likely that it is not the original persimmon cream, and consumers should pay more attention to this.
04 taste
complete sweet persimmon has a unique flavor and a sweet taste; completely astringent persimmon, incomplete astringent persimmon, incomplete sweet persimmon, and incomplete sweet persimmon after the astringent flesh is thick and even, and the taste is sweet. If the persimmon has a sour taste and is bitter, it is a bad fruit.
Is the "tags for eating persimmons" true on the Internet
Persimmons are not only good in appearance and deliciousness, but also rich in nutrition, containing a large number of sugars and a variety of vitamins, such as carotenoids , flavonoids , fatty acids, phenols and a variety of amino acids , etc.
Although there are many benefits to eating persimmons, physical discomfort caused by eating persimmons is often reported.
According to " Hangzhou Daily ", in early October, Mr. Zhang from Hangzhou, Zhejiang Province, felt nauseous and uncomfortable after eating more than 20 persimmons in two or three days, and felt "the stomach felt blocked." After being diagnosed by a doctor in the emergency department of Zhejiang University First Hospital, Mr. Zhang's symptoms were intestinal obstruction. The reason is that he eats a lot of persimmons on an empty stomach in a short period of time. After adding, Mr. Zhang tried to choose to skip rope and other vigorous exercises to relieve it, which eventually led to stones blocking the intestinal cavity.
Similar to Mr. Zhang's situation, it often becomes evidence that gastric stones will be caused by eating persimmons. In addition, the saying that persimmons cannot be eaten with milk or crabs, otherwise they will suffer from indigestion and even gastric stones is also very common on the Internet. So, is this really the case?
Gao Jie said that these statements are actually one-sided.
First of all, in clinical practice, the stones of persimmons are common in people with a history of gastric surgery, and most of them eat persimmons on an empty stomach. This situation mainly occurs because the content of tannic acid in persimmons is large. When eating persimmons on an empty stomach, under the action of gastric acid, the tannic acid in the persimmons can easily react with cellulose, hemicellulose and protein , forming water-insoluble sediments, which lead to indigestion.
Secondly, the so-called persimmons and milk or crabs cannot be eaten together is mainly because tannin will complex with proteins in milk or crabs, iron ions , calcium ions and other substances, forming substances that are not easily absorbed by the human body, which in turn affects the digestion and absorption of food. But in fact, the persimmons consumed by consumers are generally mature and deaerated, and the tannic acid content is generally below 0.5%. As long as you eat it in moderation, the tannic acid intake will not cause this. How to avoid the above situation? Gao Jie recommends that consumers pay attention to the following points when eating persimmons:
)1
suggests that consumers choose to eat completely sweet persimmons or persimmons that have been treated with deaf. Do not eat persimmons on an empty stomach, especially those with a history of gastric surgery. At the same time, because the persimmon skin has relatively more tannin content, it is recommended to peel it before eating.
)2
Control the amount of consumption. Because persimmons contain more sugar, eating persimmons is more fuller than eating the same number of apples and pears, which will affect appetite and reduce the intake of regular meals. Especially for the elderly, children, people with poor gastrointestinal tract, and patients with diabetes , it is recommended to eat less or not to eat persimmons.
)3
After eating persimmons, rinse your mouth in time to remove the tannic acid and pectin remaining in the mouth and between teeth to avoid erosion of the teeth and forming caries.
Save persimmons at low temperature and breathable
The persimmons that have not been deafened have high tannin content and taste very astringent, so you must wait until the persimmons are completely ripe before they can be eaten.
If you buy an unripe persimmon, you can gradually ripen during the storage process through some simple operations:
01
Put the persimmons that have not been deaerated and apples or bananas into a sealed plastic bag. Use the ethylene released by these fruits to promote the division of cells , so that the persimmons can be deaerated and then they can be eaten when they are softer.
02
can also be ripened at a high temperature, that is, put the raw persimmons into a container and add hot water to soak. During the soaking process, please pay attention to changing the water in time. Change it about 3 times a day. Generally, it can be soaked for about 3 days.
03
can also be evenly applied to the surface of the persimmon with gauze, put it in a carton and store it in a cool place. Generally, raw persimmons can be eaten in about a week.
Completely sweet persimmons, completely astringent persimmons, incompletely astringent persimmons, incompletely astringent persimmons, and incompletely sweet persimmons that have been removed. If you can finish it within one or two days, just put it in a ventilated and shaded place and store it. If you buy more, you need to consider the following two ways to store:
01 refrigerator refrigeration method
00 the refrigeration temperature is best controlled at around 4℃. Before putting the persimmons in the refrigerator, they do not need to be cleaned. They only need to be packed in a fresh-keeping bag to avoid the evaporation of moisture. You can put a few small holes in the bag to keep them breathable and prevent the water vapor emitted by the fruit from condensed in the bag due to respiration, causing the persimmon to rot and deteriorate. It should be noted that although the refrigeration method can increase the shelf life of persimmons, it should also be eaten as soon as possible.
02 Freezing storage method
my country Northeast region used the method of frozen persimmons for transportation and storage. Frozen persimmons is extremely hard. Before eating, soak the frozen persimmons in clean water for about 10 minutes. After the persimmons gradually soften, you can eat them. Following this idea, fresh persimmons can also be stored in the freezer of the refrigerator. However, the time should not be too long, otherwise the persimmons may lose a lot of nutrients. Similarly, persimmon cakes should be stored in the refrigerator for freezing or stored in a cool and ventilated place, but be careful to eat as soon as possible.
