It's true. Cover the honey with a paper towel, if the paper towel becomes moist, it means that the honey is mixed with water. Because paper towels have the function of absorbing water, they are a good way to test honey.
-
The method of distinguishing the authenticity of honey with paper towels is actually not rigorous. Because there is a paper way to judge honey is to drop a drop of honey on the tissue, if you find that the honey is scattered and soaked the tissue, it means that it is fake honey, if it is real honey, it will maintain its original shape and will not soak the tissue.
But this can allow the counterfeiter to make certain improvements, for example, if a thickener is added to the fake honey, then the honey will not fall apart.
-
This method is unreliable. His way to distinguish the real from the fake is whether he can get the tissue wet. Whether it is wet or not is related to the concentration of honey, and has nothing to do with whether it is true or not.

1. The honey drops directly on the paper towel, if it gradually seeps, it means that it is mixed with sugar water, and the quality of the honey is poor; If it does not seep, it means that the honey is of good quality.
For example, honey with low water content is elastic when dropped, and it is hemispherical when dropped on the paper, and does not seep out; The honey that drips into the form of water and oozes on the paper is mixed with a large amount of sugar water.
The lower the water content, the better the quality of the honey, which is high-quality honey. Therefore, this method can be used to identify the quality of honey.
2. Other relevant identification methods.
1. Look: Pure honey is a thick, viscous gelatinous liquid, bright and moist, and all kinds of honey have a fixed color, such as linden honey is light amber, clear and translucent; Sunflower honey is amber; The color of the hybrid nectar is not fixed, and it is generally yellowish-red.
Pure honey can be observed to be bright and transparent in the bright area, while adulterated honey is cloudy. Real honey has strong light transmittance and uniform color; Inferior honey is cloudy and has impurities. The new honey is light amber and transparent**.
Honey is added to boiling water, stirred slightly, and melted without precipitation, which is good honey; Inferior honey is not easy to dissolve, and there is precipitation.
2. Smell: real honey is sweet and fragrant, and fake honey has no smell. Honey mixed with spices has an unusual aroma. Real honey can give off its unique honey aroma a few months after harvesting, fragrant and long-lasting, and you can smell it when you open the bottle; Or put a little honey in the palm of your hand and rub it to smell, there is a fascinating honey fragrance.
3. Taste: High-quality honey is fragrant and sweet, and has a long aftertaste after entering the mouth. The adulterated honey has no floral fragrance, and some fake honey has the taste of boiling sugar, and the taste of white sugar water has been tasted carefully. Pure honey crystallizes quickly in the mouth, and has a strong floral fragrance; The crystals of adulterated honey are not easy to dissolve in the entrance and have a peculiar smell.
Honey is refreshing and sweet and never prickly in the throat.
4. Chemical inspection:
Honey mixed with starch will turn blue when iodine is added to the solution; Honey mixed with caramel appeared white flocculent after adding high concentration ethanol; Honey mixed with other impurities, sticky sticks attached to the red-hot wire.
5. Refrigerated crystallization inspection
Honey will become solid after being stored in an environment of 4 to 14 degrees Celsius for a period of time, which is a physical phenomenon of honey.
The crystals are pierced with chopsticks, which are very soft, and the fake honey cannot be pierced.
The real honey is pinched by hand, and its crystals dissolve quickly. Fake honey has the feeling of being in the hands and melts slowly or does not dissolve, the real honey crystal has a small sound of biting with teeth, while the fake honey crystal is crisp and loud.

Taking the paper towel method as an example, if you drop honey on a paper towel, it is real honey that is not easy to seep out, and what is easy to penetrate is adulterated and inferior honey. Is this really true? Don't forget, those concentrated honey drops on the paper towel are not easy to seep out, so it seems that the drip paper towel method is actually only the water content of the honey, and cannot accurately distinguish the authenticity of the honey.
And now there is a little bit of technical fraud, and it is impossible to distinguish without professional analysis, so it is best to use the test when buying honey. The honey fingerprint, newly developed by the Honey Research Institute and the Chinese Society of Beekeeping, is currently highly accurate. What should and should not contain natural ripe honey is very clear and clear, so that people can see it at a glance.

Prepare a paper towel, drop the honey on the paper towel, if the paper towel absorbs, then the honey is mixed with water; If it is not absorbed by the paper towel, it means that the honey is of good quality; Of course, honey with lower water content has better quality effect, and you can identify honey by the paper towel method.
It is reported that there are 80% fake honey on the market, I often bought fake honey when I first ate honey, and then I went to test every honey I ate, and now I eat Zhongbao linden honey, and all the data are higher than the standard of first-class honey.

Hello, teach you a few ways to identify the authenticity of honey:
Take a look at the gloss and color: real honey is better with light white texture with the naked eye, light yellow or amber, and light light color is better; The gloss is not very translucent. Fake honey is bright in color, boiled with white sugar or passed off with syrup, so it looks very clear and translucent, generally light yellow or dark yellow.
In addition, pure honey is colorless, and the color of honey is caused by the pollen of different plants in honey. Therefore, dark honey is more nutritious than light-colored honey, but dark honey often contains a stronger odor, such as buckwheat honey; Light-colored honey generally smells fragrant, such as lychee honey and locust honey.
Two impurities identification: you can use the red-hot wire to insert into the honey, the bubbling is the real honey, the smoking is fake, if it is pure honey, after the wire is pulled out, it is very smooth and does not attach impurities. Pick up honey with chopsticks, which can be pulled into long filaments, keep flowing, and those that will automatically retract when the filaments are broken and are spherical are of the highest grade.
Mix honey and water in a ratio of 1 to 5 and leave it for a day, and it is best to have no sediment.
Three water identification: honey drops on white paper, pure honey into beads, will not seep, and water-mixed honey will gradually seep out, the faster the seepage, the more water.
4. Identification of heavy metals: take a tablespoon of honey and add it to a small half cup of very strong herbal green tea, if the honey has been contaminated by heavy metals, the tannins in the tea will react with the heavy metals in the honey to produce gray or brown and black salts. The darker the color, the greater the degree of heavy metal contamination.
5. Starch identification: put a small amount of honey into a cup, add an appropriate amount of water to boil, drop a few drops of iodine wine and shake well after cooling, if the solution turns blue or red or purple, it means that the honey is mixed with starchy substances.
6. Sugar identification: honey mixed with sugar has poor transparency, is not clear, turbid, and has poor floral flavor. Honey mixed with brown sugar is darker, and honey mixed with white sugar is lighter. You can rub it with two fingers to feel sticky, and if it is grainy, it is good.

The method of identifying the authenticity of honey with paper towels is as follows, drop a drop of honey on the paper towel, observe after a few minutes, if the honey penetrates the paper towel, then the honey is considered fake, if it does not penetrate the paper towel, then the honey is real. In fact, this method is to detect the water content of honey, if the honey penetrates the paper towel, it means that the water content is large, if the honey does not penetrate the paper towel, it means that the honey has a small water content.
-
As a beekeeper, I can tell you responsibly that the method of measuring the authenticity of honey with paper towels can only measure the moisture content of honey, not the authenticity.
-
Paper towels can only indirectly measure the water content of honey, good honey generally has less water content, more water content means that it may be honey or mixed with something, honey as the name suggests is a honey with more water content without a cover, such honey is not convenient for long-term storage and low nutritional value, but the spring honey is larger than the winter honey even if the water content is larger, after all, there is more rain in spring, the air is moist, but this is still very different from the water content of honey.
There are many ways to measure the authenticity of honey, such as smelling the smell, shaking it with water to see the bubbles, the granular thickness after crystallization, etc., now the counterfeiting technology is getting higher and higher, it is recommended to go to a familiar and assured place to buy it.
-
Using paper towels can not distinguish the authenticity of honey at all.
The principle of paper towel identification of the true and false of zhi honey is to see whether it can penetrate the inner paper towel, but because the honey contains a certain amount of water, it is obviously unreliable to use paper towels to identify the true and false, at best, it can only roughly identify the water content of honey, and the water content of honey is directly related to the honey source, climate and maturity. Therefore, it is impossible to distinguish the authenticity of honey with paper towels.

No one is allowed to say that as long as you drop a drop of honey on a napkin, you can know the "authenticity" of honey by looking at the elephant. If there is no honey.
It penetrates the paper towel and does not seep out.
genus, there is not a single water stain around, that is, real honey; If there are water stains around the honey and gradually spread out, it is fake honey.
Honey can only be roughly identified by testing honey through napkins, and honey with water stains is not necessarily fake, but it only means that it contains more water, and this honey is not easy to store and easy to ferment at high temperatures.
To distinguish the authenticity of honey, you should not only look at the moisture, but also look at the color and taste. The first is to look at the color, for example, acacia honey, its color should be water white, relatively transparent, if the color is darker, it may be mixed with other honey or sugar water. In addition, the taste of honey is also very important, real honey is soft and elastic in the mouth, and has a floral aroma, while fake honey is not elastic and will be a little jerky in the mouth.
-
Accurately, the honey does not diverge around, indicating that it is pure honey.
-
No, the experimental argument is a lie.

Paper towels can be used to go to the bathroom, wipe hands, wipe nose, wipe face, etc., I think the invention of paper towels has really brought a lot of convenience to our lives; But you guys can't waste paper towels!
Of course, there is a cost to the one-dollar paper towel sold in the store, and this cost is very low, so low that you can't imagine it, maybe it costs only one dime or two centsHe still has a considerable profit margin for buying a dollar, because if you buy it online, you will often find some merchants to make discounts, 10 packs of tissues only need a few dollars, and free shipping. <> >>>More

First. It can absorb water, because there will be residual water on the washed shoes, and there will be residual soap in the water, if the water stays for a long time, it will inevitably hurt the shoes and turn yellow, so wrapping it in paper will wash the water out and reduce the residence time of the water on the shoes. >>>More
