Look at the fluff. Everyone knows that there are a lot of fluff on the tail of chestnuts, and the surface is shiny, and the hairs on aged chestnuts are generally relatively small, only a little at the tip of the tail. The tail of the new chestnut is generally more fluffy, such chestnuts are relatively fresh, we are suitable for eating such chestnuts, we can't miss such high-quality chestnuts when choosing.

It depends on the head. There is a kind of Japanese chestnut, which is very large and very pleasing, but this chestnut has a lot of moisture, less sweetness, high yield, and the taste is not as sweet as the domestic variety. The second type is the common medium-sized common variety, which has some differences in taste depending on the place of origin.

The third type is not very common, it is very small, but this is generally mountain chestnut, a real green food, with a sweet taste.

It depends on the shape. Common chestnuts are roughly divided into two shapes, the first type is round on one side and flat on the other; The second type is flat on both sides. When choosing, choose the first one if you want to be sweet, and choose the second one if you want to be sweet.

The reason is very simple, from the analysis of the growth state of chestnuts: chestnuts are several together on the tree and are wrapped in a green thorny shell, the chestnuts close to the shell have a round side, and the one that is sandwiched in the middle will of course be flat on both sides, and the chestnuts closer to the shell are more likely to receive sunlight. The sugar content of many fruits also has a lot to do with the time of daylight.

That's why chestnuts on the outside are sweeter than on the inside.

Chestnuts are the food we all like to eat in life, we often eat chestnuts is very beneficial, first of all, it can help us effectively supplement a lot of nutrients, and chestnuts are also very delicious, so we can not miss such delicious food as chestnuts, we must learn how to choose.

If there are no insect eyes on the surface, if you are still not at ease, you can rub the skin of the chestnut with your hands, and then there are still no insect eyes on the surface, most likely there are no insect eyes.

4. Look at the head.

There is a kind of Japanese chestnut, which is very large and very pleasing, but this kind of chestnut has a large moisture, less sweetness, and high yield, and the taste is not as good as that of domestic varieties of noodles and sweetness.

1. Touch it with your hand.

When buying chestnuts, bring a few tissues and wipe the shell of the chestnuts first. If you find oil stains on it, it means that the chestnuts may have paraffin oil added (some people add vegetable oil when frying chestnuts, but the amount added is relatively small), it is best not to buy it. Bee sugar chestnut color is dark, yellow-red, after loading into the paper bag, there will be mimeograph on the paper bag, and wax fried chestnut, the color is particularly bright, the color is very yellow, the skin is thin, after being loaded into the paper bag, there is no mimeograph on the paper bag.

Be sure to touch the chestnuts before buying, the chestnuts fried in pure honey are a little sticky to the touch, and the bee candy chestnuts are very sticky to the touch. And if it is fried in wax, the chestnut is not sticky to the touch, but also slippery, and the more you rub it, the brighter it becomes.

2. Look at the color of the pulp.

When buying chestnuts, don't blindly pursue the color of the flesh white or golden. The flesh of the fruit that is too golden in color may have been chemically treated. On the other hand, if you find that the flesh is a little brown in the middle after sautéing or cooking, you don't need to worry.

This is caused by the "browning reaction" of the enzymes contained in chestnuts, and as long as the taste does not change, there is no harm to the human body.

When buying chestnuts, be sure to pay attention to the shape of the chestnuts, do not buy chestnuts with spots or moldy deterioration, when buying, pay attention to the taste of chestnuts to be fragrant, the taste is relatively dense.

Don't buy chestnuts that are very shiny after being fried, because these chestnuts will have added saccharin and industrial paraffin, which will be harmful to the body after eating.

You can't buy chestnuts that are damp, chestnuts that have black spots, chestnuts that have white spots, chestnuts that have spoiled can't be bought, and chestnuts that have turned black can't be bought.
