How to judge the quality of walnuts?

Question 1: How to judge the quality of walnuts? The key points of selecting walnuts are summarized as "look, touch, smell and listen".

Look: the walnuts should be even in size and the sutures should be tight. The shell is white and smooth. Most of the fruits that are black and oily are bad fruits.

Touch: Just take a walnut and weigh it. It is light and has no weight. Most of them are empty or bad fruits.

Smell: Put a few walnuts under your nose and smell them. Old and bad fruits have a distinct smell. If you crack the walnuts and smell them, the smell will be more obvious.

Listen: Throw the walnut on the hard ground from about 1 foot high and listen to the sound. The empty fruit will make a sound like a broken ping pong ball. Those few good walnuts are inferior to the empty walnuts, and the sounds are obviously different. When buying in large quantities, experienced experts can basically judge the quality of the pile of walnuts by picking them up a few times with their hands and listening to the sound.

The quality is mainly determined by observing the kernels. Plump kernels are the best, and shriveled ones are the second best. The color of the kernels is yellow-white, dark yellow, and brown-yellow. The quality of "tiger skin walnuts" with dark brown markings is also not good. Peach kernels that are white, clean and fresh are considered the best, and those with oily "chrysanthemum hearts" are considered inferior; peach kernels that are all oily and dark brown have been severely spoiled and cannot be eaten. If the walnuts are light and weightless in your hand, it usually means they are not ripe. They may have been picked on a hot day, which means they are six ripe.

Question 2: How to judge the quality of Wenwan walnuts? I don’t know where I copied what was said above.

Let me briefly talk about my experience playing with walnuts in the past few years.

First of all, you need to understand the varieties of walnuts. Wenwan walnuts are divided into chicken heart hats, Qiuzi iron walnuts, lion heads and tiger heads

Among them, chicken hearts are divided into original piles and splints, and hats are divided into official hats and prince hats. Baihuashan, Qiuzi is basically both Wild ones are divided into several types according to their place of origin. There are more than ten varieties of lion heads, and there are three types of tiger heads: wheat tiger, liger and tiger head.

Among them, Qiuzi and Tiewalnut are basically wild, with high yield and low value. Qiuzi is basically sauce-colored when played, and Tiewalnut is even more difficult to color red. These two types of walnuts are low-end among Wenwan walnuts

The mid-range ones include chicken heart and young man’s hat

The high-end ones are tiger head, lion head and official hat. Here they are divided according to varieties.

Let’s talk about the size. The size of walnuts is measured by the width of the two sides. Generally, those below 40MM are basically not sold at high prices. 40-43MM is a grade, and 44-46MM is a grade. 47 -49MM is a grade and above 50MM is another grade. When the same type of walnuts are paired with similar farm types, the larger the price, the more expensive it is.

Then let’s talk about how to check the quality of walnuts. First, check that there are no yellow tips or yellow tendons on the outer skin of the walnuts. Don’t believe the merchants who say that it will go away after playing for a while. The yellow color comes from the inside of the walnuts. The more you play with it, the more obvious the color difference becomes. Secondly, you need to check whether the shape of the walnuts is straight. Place the walnuts on the table and stand them upright without looking upside down. Thirdly, you need to check whether there is any obvious "missing meat" in the grain of the walnuts. "Phenomenon.

Having said so much, I first suggest that if you want to buy Wenwan walnuts, you should at least be able to identify the types of walnuts. There is a lot of water in them, and there are many tricks to deceive them. If you don’t understand it yourself, If you don’t understand the market and all kinds of tricks, just wait to pay the tuition.

Question 3: How to distinguish between good and bad walnuts? The key points of selecting walnuts are summarized as "look, touch, smell and listen". Look: the walnuts should be even in size and the sutures should be tight. The shell is white and smooth. Most of the fruits that are black and oily are bad fruits. Touch: Just take a walnut and weigh it. If it is light and has no weight, most of it is empty or bad. Smell: Put a few walnuts under your nose and smell them. Old and bad fruits have a distinct smell. If you crack the walnuts and smell them, the smell will be more obvious. Listen: Throw the walnut on the hard ground from about 1 foot high and listen to the sound. The empty fruit will make a sound like a broken ping pong ball.

The few good walnuts are inferior to the empty walnuts, and the sounds are obviously different. When buying in large quantities, experienced experts can basically judge the quality of the pile of walnuts by picking them up a few times with their hands and listening to the sound. The quality is mainly determined by specific identification and observation of the kernels. Plump kernels are the best, and shriveled ones are the second best. The color of the kernels is yellow-white, dark yellow, and brown-yellow. The quality of "tiger skin walnuts" with dark brown markings is also not good. Peach kernels that are white, clean and fresh are considered the best, and those with oily "chrysanthemum hearts" are considered inferior; peach kernels that are all oily and dark brown have been severely spoiled and cannot be eaten. If the walnuts are light and weightless in your hand, it usually means they are not ripe. They may have been picked on a hot day, which means they are six ripe.

Identification of hemp walnuts The quality of hemp walnuts is mainly identified through four senses: touch, smell, hearing, and vision. To identify hemp walnuts, take a pair of walnuts and put them in your hands. That is to say, the weight should be enough relative to its size. If the walnuts are light and weightless in your hand, it generally means they are not ripe. They may have been picked on a hot day, which means they are six ripe, so don't buy new walnuts every September. Also, remember that when asking others for advice, you learned that good walnuts should be pricked in the hands. This is the acupuncture point on the hand where the walnuts are located, an important indicator of health care. The identification of hemp walnuts depends on the sense of smell. This is my own idea. Truly unprocessed walnuts have a unique smell and no strange taste. For new walnuts, you can tell whether they have been processed. Because things soaked in hydrogen peroxide have a chemical smell, which is very pungent to the nose. Of course, it can also be distinguished by traditional skin color. Hearing of identification of hemp walnuts. This is a relatively easy way to distinguish wild and grafted walnuts. Take it in your hands and rub it. If the so-called golden and stone sound is very real and tough, it means mature wild walnuts. If the sound of Pila Pila is empty, it is probably grafted. To use an analogy, it's like the difference between a solid wooden ball and a table tennis ball in your hand. If the walnut skin feels soft, it usually means it was picked early. Vision is the main and important aspect in identifying hemp walnuts.

Question 4: How to distinguish between good and bad walnuts? When purchasing walnuts, generally choose ones with a bright color (bright brown is best) and a heavier feel. The surface of bleached walnuts is whiter but lackluster. Although walnut shells are hard, if they are soaked in chemicals, they will also contaminate the kernels in the shells, so try not to choose brown-white walnuts.

Good walnuts are not bleached, they are buried in the soil. The skin of the walnuts is slightly black, while the bleached walnuts are white and look very clean, but you can know the bleached walnuts without asking. Not as good as pure natural ones

Question 5: How to identify the quality of walnut kernels? The appearance color of a good walnut kernel should be golden or light yellow, slightly less brown or light brown. If it changes When it turns into dark coffee or black, you need to pay attention. At this time, you need to break the walnut kernels to check. If they are crisp when broken, and the cross section is white, clean and not greasy, it proves that the walnuts can still be eaten, otherwise they are bad. .

Hope to adopt

Question 6: How to identify the quality of walnuts and fake walnuts, summarized in four words: look, listen, touch and smell.

1. Look: Fake walnuts are usually made of "old walnuts". Old walnuts are easy to fake, and white-skinned walnuts are difficult to make. However, now there are new walnuts made of walnut powder and resin, which can also be plated. Red; pay attention to the edges. The edges of fake walnuts are usually clearly divided into two halves. The dividing line is very clear, and some transparent glue is applied between the edges. The seams are very unnatural. It is the most difficult to make fake walnuts. It is the horizontal stripes that make the edges. Fake walnuts generally have two halves on the edges. There is no horizontal stripe connection between the edge seams. If there are horizontal stripes, they end at the middle seam and will not be connected to the other side of the middle seam. Pay attention to the tail, fake walnuts Sometimes the tail of the old walnut is coated with something like transparent glue. If the bottom of the old walnut is newly sealed with white wax, it is 80% fake, because if the bottom of the old walnut is sealed with wax, it will be too early. It is sealed. As time goes by, the wax will not be white; pay attention to the variety and appearance. Generally, fake walnuts are made of old walnuts with rare varieties, such as: old style dull pointed lion heads, four-sided lion heads, etc. So be careful on this point.

In addition, fake walnuts are generally in perfect appearance and have no defects such as knocks, falls, or residue. Let’s think about it carefully: if decades-old walnuts are real, it would be extremely difficult to survive them unscathed; pay attention to whether there are any similarities. The varieties of fake walnuts are limited. As long as you travel a lot, you may encounter them. to the same fake walnuts.

2. Listen: Old walnuts generally contain amomum villosum. After decades of playing with the walnuts, the kernels have become deserted. Low-level fake walnuts do not have amomum kernels, but some counterfeiting masters will also make amomum kernels, which are made of millet. However, this kind of amomum kernels will be louder and smoother when shaken than the amomum kernels of real walnuts. This is important. The sound made when plating walnuts cannot be imitated by fake ones. It will not have the pleasant sound of real walnuts, only a muffled sound.

3. Touch: It means "feel". It is difficult to judge the Taoist practice without a certain amount of Pan Gong. Old walnuts are generally very light and have no falling feeling, and they feel a bit "floating" after being weighed a few times. Fake old walnuts are a bit clumsy. Although the weight and size match well, the subtle changes in the wood cannot be faked! It doesn’t feel that warm to the touch either! In addition, the real patinated walnuts will feel greasy after being plated for a few times; the artificial patinated walnuts will not have this feeling and will be rougher!

4. Smell: Walnuts made of resin smell like chemical products with your nose, but real walnuts have no peculiar smell.

Question 7: How to identify the quality of Wenwan walnuts? Wenwan walnuts pay attention to the four words "quality, shape, color and individuality" and "quality". The texture of good walnuts is fine and hard, and new walnuts sound like porcelain when they collide. Solid and heavy in hand. Old walnuts are as smooth and smooth as mutton-fat jade when rubbed, and like gold and stone when collided. "Shape" refers to the texture and pairing of walnuts. The closer two walnuts are, the more precious they are. The density and distribution of the texture, the width and thickness of the sides are an important factor in measuring walnuts. "Color" refers to the different colors that walnuts of different periods present. Older walnuts will appear as transparent as ruby. It should be noted that there are currently some colored walnuts on the market. In fact, they have not been around for a long time, so they need to be carefully identified. A simple method is to rub it hard with your fingers. Old walnuts will have bright spots, while new walnuts will have no bright spots. This is what collectors call walnuts, whether they are popular or not. "Ge" refers to the size of the walnut. Generally speaking, the bigger the walnuts are in good quality, the more valuable they are, but the most important thing about special-shaped walnuts is that they come in pairs. There are no identical walnuts in the world, just like there are no identical eggs in the world. Often a pair of exactly similar walnuts cannot be selected from a train of walnuts. Pairing requires great patience and opportunity, so a pair of well-matched special-shaped walnuts The often valuable walnut selection skills are divided into touch, smell, hearing and vision. First of all, touch is touch. Take a pair of walnuts and put them in your hands so that they are smooth, that is to say, the weight should be enough relative to its size. If the walnuts are light and weightless in your hand, it generally means they are not ripe. They may have been picked on a hot day, which means they are six ripe, so don't buy new walnuts every September. Also, remember that when asking others for advice, you learned that good walnuts should be pricked in the hands. This is the acupuncture point on the hand where the walnuts are located, an important indicator of health care. Smell Speaking of smell, truly unprocessed walnuts have a unique smell without any strange smell. For new walnuts, you can tell whether they have been processed. Because things soaked in hydrogen peroxide have a chemical smell, which is very pungent to the nose. Of course, it can also be distinguished by traditional skin color. Hearing Let’s talk about hearing. This is an easier way to distinguish between wild and grafted walnuts. Take it in your hands and rub it. If it is the so-called sound of gold and stone, which is very real and tough, it means mature wild walnuts. If the skin is The empty sound of Lapira is probably grafted. To use an analogy, it's like the difference between a solid wooden ball and a table tennis ball in your hand. If the walnut skin feels soft, it usually means it was picked early. Vision Finally, vision is the main and important aspect. Divided into two categories, one is natural conditions, and the other is natural conditions that can be regarded as man-made factors. For a pair of walnuts of the same variety, size and texture are the two more important aspects. Everyone knows that walnuts are measured in millimeters, and good things tend to be larger and have a greater impact on price. Therefore, try to choose one that is as large as possible. It is generally best to use a caliper to measure the size.

The aspect of texture is more complicated, and it’s hard to explain clearly. I can only give a simple example. For example, the lion’s head is called a lion’s head. As the name suggests, its texture should be like lion hair, which means that it must have a pattern. , or twisted pattern, cannot be like an ordinary straight grain. In addition, for real walnut playing, it is generally better to choose deep and large textures. Compared with dense textures, it can produce pulp and retain the texture of walnuts. Textures like dense textures are easier to wear away. In addition to the main factors, there are many other aspects. For example, the eyes of walnuts must be small and straight, but it is not good if they are too big or too crooked. The growth of walnuts can also be seen with the naked eye. Also, the walnuts must be straight and not crooked. If they are all crooked, that’s fine, but if one is crooked and none is crooked, that’s it. Others include being able to stand on a table, being symmetrical, making the two as similar as possible, etc. Another major aspect is the so-called human factors, which mainly include vulva skin, damage, cracking, and repair. As for the vaginal skin, a subtle one is okay. If it is a more obvious vaginal skin, it must not be selected. Dirty walnuts, that is, obvious vaginal skin, can be said to degrade the walnuts. Moreover, after questioning, it is no exaggeration to say that the vaginal skin can be easily or even irreparably removed with potions or other treatments in the future. The potion can only remove the superficial vaginal skin, which will reappear after playing with it for a long time; it is also difficult to find it after getting started. You also need to look carefully for damage, because walnuts have many lines. You need to be very patient to see all the damage on a pair of unfamiliar walnuts. Pay attention to every sharp corner and every edge. Cracks usually occur on the edges, that is, at the seams, and on the ***. You should also pay attention when looking at it, and of course you should distinguish it from black ribs, not cracks. Wenwan Walnut talked about cracks and cracks, and it was repaired naturally. Many walnuts are tampered with due to defects of one kind or another. Here are a few ways...gt;gt;

Question 8: How to identify the quality of walnuts? When purchasing walnuts, generally choose ones that are bright in color (bright brown is best) and have a heavier feel. The surface of bleached walnuts is whiter but lackluster. Although walnut shells are hard, if they are soaked in chemicals, they will also contaminate the walnut kernels in the shells, so try not to choose brown-white walnuts. Good walnuts are not bleached and are buried in the soil. The skin of the walnuts is slightly black, while the bleached walnuts are white and look very clean.

Question 9: How to tell if the walnuts are bad? It's hard to tell by looking at the outer skin. If there's a strange smell when you eat it, or there's a dust-like net, it means it's been too long.

Question 10: How to distinguish the quality of Wenwan walnuts? First, look at the cortex. There are no wounds, no yellow tips, and no vaginal skin. Uniform color. The one with pink and reddish color is best and quick to use.

Then there is the matching. The more similar the better, the smoother the texture, the clearer the better.

Weight is also important, the heavier the better.

There are too many varieties of walnuts in Wenwan, and different varieties are good or bad. Hemp walnuts are the best. Don't listen to the nonsense on the Internet. Only by going to the market to see more can you learn. To play with collections, you must come out to "mix"
