Since people have advocated green diets and health preservation, the status of nuts seems to be rising invisibly. People have found that eating a little nut every day can absorb the high-quality oils in the nuts and obtain the nutrients of the nuts. Small nuts not only taste delicious, but also have a filling effect. They can be used as small snacks when young people are greedy. They not only supplement nutrition, but will not gain weight.
People have found that walnuts, pistachios, cashews, macadamia nuts, pecans and other nuts not only contain unsaturated fatty acids that protect the cardiovascular system, but also vitamin E to slow down aging. In addition, the protein and minerals of nuts The content, plant-based protein, trace elements, fiber, etc. are very high. The so-called "concentration is the essence." Nuts have become one of the favorite snacks of young people. But do you know that the growth of these nuts we often eat is a bit strange. Such as walnuts, cashews and pistachios.
Walnut, a kind in inland ChinaNuts grown in large areas in the region. There are many fine walnuts in China, among which Lin'an pecans are particularly famous. But if you want to get these pecans, you first need to spend a lot of energy. Pecans grow on tall and thin walnut trees, and each walnut fruit is wrapped in hard flesh. Professional walnut beating villagers risk their lives by beating the pecans from the treetops and dropping them on the floor. The villagers below will seize the time to pick them up.
When you return from picking pecans, try to wear gloves, because the flesh of pecans is poisonous. Lin'an people who often peel pecans have black fingernails because of toxins.Eroding the fingers, leaving black marks on the fingers. The flesh of the walnut needs to be removed with a special walnut knife, and the walnut kernel inside is dug out, which is the walnut we eat. It has a hard shell and the walnut kernel is wrapped inside.
Cashew nuts, a kind of nut with a very strange growth pattern. At first glance at the appearance of cashews, I can’t think of any connection between it and the crescent-shaped cashews we often eat. Only when I see the curved gray tissue structure under the fruit, I will find that this is the cashew. . The red pulp on cashews is not edible and must be removed. Cashew nuts are actually the seeds of the whole cashew tree, but the waistThe shell of the fruit is never on the market, because the shell has a highly toxic substance called "cashew nut shell liquid".
In ancient times, when people took cashews, they had to pick them off, dry them, and roast them on the fire. High temperature will volatilize cashew nut shell liquid and reduce its toxicity. When the cashew nut shell liquid is almost volatile, the gray shell of the cashew nut bursts, and the cashew nut kernel inside can be taken out. It was not until the emergence of special cashew nut shelling machines in modern society that it was not so troublesome for people to process cashew nuts.
Pistachio, because after eating this kind of nut, people's mood will become happy, as the name implies, "pistachio." There is a seam in the white shell of a pistachio, this seam is the key to open the shell , But do you know how this seam of pistachios comes from? In fact, this seam of pistachios grows by itself, but not all pistachios can sew on their own. Generally speaking, as long as it grows Only ripe and good quality pistachios will list a seam.
The seams on most pistachio shells are neat and symmetrical, and even the length is almost the same. Such seams are repaired by machines, so that customers can open them without the help of tools after they buy them home. Fruits. Compared with ripe and slit pistachios, the pistachios with machine slitting taste worse, because the quality is not good, and they have not waited until they mature naturally. It is worth mentioning that the original color of the pistachio shell is light Yellow, it becomes our common white after bleaching.
