The thirteenth note on the study of the original bee: criticizing the unreliable identification method of fake honey one by one
The methods circulating on the Internet to identify fake honey are very unreliable. Not only can they not identify fake honey, but they also deliberately mislead consumers. This is not limited to the internet, but also the media has moved these methods to newspapers, which is extremely harmful and widely spread. It is necessary to clean up these identification methods one by one in order to trace the source and remind consumers.
I summarized some common identification methods, and analyzed the "identification method" without instruments:
1, look at the color: true honey is transparent or translucent, so it doesn't look very clear, white, light yellow or amber, light color is preferred. Fake honey is bright in color, usually light yellow or dark yellow, because it is boiled with white sugar or impersonated with syrup.
Comments: The best acacia honey is water white. The clearer it is, the higher its quality is. The color of honey can be divided into white, yellow, brown and reddish brown. Dark honey, such as jujube honey and wild chrysanthemum honey, is yellowish brown or reddish brown, such as buckwheat honey, eucalyptus honey and chestnut honey is dark amber. Fake honey is light yellow or dark yellow, but neither light yellow nor dark yellow honey is necessarily fake honey.
2, look at the shape: true honey is a viscous liquid, stirring up visible flexible filaments and constantly flowing. False honey has suspended matter or precipitation, and its viscosity is small. When it is stirred, it falls drop by drop and then is cut off. If honey is extremely thin and easy to flow, it may be mixed with water.
Comment: Try a bottle of maltose. It can be seen that it is "soft silk" and "continuous flow". Is maltose honey? As for "the viscosity is small, it drops when stimulated, and there is a cut-off", which cannot be used as the basis for identifying fake honey: First, this technical "problem" has long been overcome by counterfeiters; Second, some bee farms are immature honey, which is extremely rare, but it should be counted as honey, not fake honey, but of poor quality. The idea of mixing water is even more misleading. Will you mix water to make it more like fake honey? Are counterfeiters so stupid?
3. Look at the label: some ingredients of honey products are marked with sucrose, white sugar, fructose syrup and other ingredients, but pure honey products are not allowed to add these substances.
Comment: More unreliable. Do you think it will be easier to identify counterfeiters if you directly label "fake honey"? Are counterfeiters so stupid? Forgers don't label these ingredients at all, but people who label these ingredients will write "honey cream" and "honey dew" on the label. Honey cream and honey dew are not equal to honey and cannot be regarded as fake honey. Can only blame consumers for not understanding, honey mixed with any substance can no longer be called honey, only honey cream and honey dew. People are mixed with other substances and are not called "honey". What makes you say that people are fake honey?
4. Smell: Real honey smells pure and natural, with a faint floral fragrance, while fake honey smells pungent or fruity.
Comments: buckwheat honey has a strong irritating (smelly) smell; Toona sinensis honey smells like Toona sinensis flowers (similar to bad sweet potatoes). These are real honey. Some people say that the example I gave is that it takes two hands to make a sound, but most people's noses are not as sensitive as hounds, and they can clearly distinguish what is a normal smell and what is a strange smell. Concentrated honey is basically bland and tasteless, and most of them have some unpleasant smells. Can they be regarded as fake honey? In the honey market in China, concentrated honey accounts for more than 90%!
5, taste the taste: true honey is sweet and delicious, with a sticky taste, slightly sour taste and a long aftertaste. When you taste the crystal block, your teeth will be brittle and it will melt. If you taste the fake honey carefully, it has a bitter taste or a strange smell of chemicals, but it has no aromatic fragrance. The crystal block chews like sugar, and its voice is crisp and loud.
Comment: Concentrated honey tastes bad, too. Many people can't smell the flowers and have a short aftertaste. As for convergence, we should also analyze it in detail. The astringent mouth may be fake, and the one that does not astringent throat may also be fake-honey contains alkaloids, and it is normal to astringent throat. As for crystallization, not all honey is crystallized like sugar. For an extreme example, Yunnan wild bazi honey is called "Yunnan hard honey" because of its thick crystal and hard texture. Is it fake honey?
6, exudation method: drop honey on toilet paper, if the honey on the paper gradually oozes, it means that it is mixed with sucrose and water.
Comment: Immature honey is easy to seep out, but it is not fake honey; Maltose is impermeable, but it is not honey. Natural mature honey, not easy to ooze, high quality honey; Concentrated honey, not easy to ooze, inferior honey; Maltose, not easy to ooze, not honey; Immature honey, easy to ooze, is true honey (and of course inferior honey). The situation is still complicated.
7. Wire method: insert the red-hot wire into honey, and if black smoke comes out, mix it with white sugar; If steam comes out, it means it's real honey. If a sticky substance is attached to the wire, it means that there are impurities in it; If the line is still smooth, there is no impurity.
Comment: this method can be tried in the second half of the sentence, and the first half is not reliable. Red-hot wire is inserted into honey, whether it is steam or smoke, how much will it be? Can you tell the difference? Of course, big smoke and big steam can be separated, but how can you clearly distinguish a faint smoke or gas?
8. Crystallization: It is easy to distinguish the crystallization of real honey from the precipitation of fake honey. The crystallization of real honey is soft and easy to insert with chopsticks, while fake honey is not easy to insert with chopsticks. The crystallization of honey is melted by hand, and it melts when it is filled; The crystal block of fake honey, twisted and ground by hand, feels gritty, chews like sugar, and is crisp and loud.
Comments: Some honey crystals are thicker, such as butter honey, sesame honey and eucalyptus honey; Some honey crystals are hard, such as ear honey, wild barley honey and cotton honey. I also found some strange honey as an example, which belongs to wrangling, but how many people can clearly tell the difference between "melting with their hands" and "grinding their hands with their hands", and as for "chewing like sugar, crisp and loud", it is too exaggerated.
In fact, the situation of fake honey is extremely complicated, including all fake syrups, semi-fake syrups and honey, and a small amount of "micro-fake" syrups ... And counterfeiting is not just a kind of syrup, and it is really a ghost to rely on these manual identifications without the help of instruments! Many of them are difficult to identify with the help of high-end instruments. How can you tell the truth by "seeing, smelling and tasting"? Therefore, this method of identifying true and false, consumers laugh it off, take it seriously, and will inevitably not be misled.

Note 12: The method of identifying fake honey online can only lead you to into the pit.
My friend keeps asking me: How to distinguish true honey from false honey? I said, I don't know, there's nothing I can do. The friend said, you don't seem to know much about it, and you can't identify it! I smiled because I knew, just to tell you that I couldn't identify it.
Imagine: If real honey is so easy to identify, will fake honey flood? If fake honey can be identified by these methods, what do companies that buy honey need professional tools for? -Aren't they more professional and experienced in identifying fake honey than we are?
Using these methods to identify, the author has learned a painful lesson. When I first came into contact with honey, I identified one of the best honey by these methods, a brand in Shanghai. I'm so excited that I finally found the best honey. Who knows, online, in a test by Liaoning Industrial and Commercial Bureau, the honey content of this brand is zero, that is, a bottle of 100% pure syrup! God, this is so interesting!
Don't give up, only blame yourself for not being tall. Still rely on this method, identified a brand of honey in Zhengzhou as "good quality", and later found that pure motherwort honey should be light amber, but this motherwort honey is actually dark brown. Sampling allows experts to identify by experience. It turns out that this so-called motherwort honey is suspected of buckwheat honey (although it is not directly identified as fake honey, I am very uneasy about such a dishonest enterprise). I was fooled again and was completely disappointed with these appraisal methods. Not only can't help you identify true honey, but also deliberately lead you to into the pit.
The author briefly summarizes the following problems in these appraisal methods:
1, confusing the identification range of authenticity and advantages and disadvantages.
Many professional books call these methods "quality appraisal", which is not bad. Quality includes authenticity and pros and cons, but many consumers simply think that these methods are used to identify authenticity. For example, the method of wire drawing, immature honey in bee farm, wire drawing is not good, but it is real honey; A bottle of maltose can get good silk, but it is not honey.
2. Many methods are limited to identifying common honey species.
For example, through the "look" method, real honey is yellow or light yellow, and many consumers mistakenly think that dark honey is fake honey. For example, buckwheat honey is very dark, but it is really honey. For example, honey should be sweet, fresh and pleasant, but some low-grade honey is not like this at all. These methods are generally limited to identify common honey species such as acacia honey, jujube honey and Vitex negundo.
3, lack of reference, the scale is difficult to grasp.
For example, sweet, taking acacia honey as an example, is it sweeter or slightly lighter? What kind of sweetness is normal, what kind of sweetness is too sweet and what kind of sweetness is not too sweet. This is difficult for beginners to master. . Maybe you have been drinking fake honey, which is very sweet. Next time you drink real honey, discard it as fake honey.
The seller of concentrated honey intentionally misleads consumers.
For example, dripping on toilet paper to see water seepage can only exclude immature honey sold by bee farms, which has nothing to do with the authenticity and quality of honey. Toilet paper tests maltose drops, which are also difficult to penetrate. Is it real honey? Concentrated honey is also difficult to penetrate. Is honey delicious? Although the penetration of natural mature honey is not good, it is not necessarily all natural mature honey, which may be bad honey or fake honey.
5, far behind the scientific and technological progress of fake honey.
Now that honey counterfeiting has reached the information age, the identification method still stays in the primitive society. Can we identify fake honey? These methods in the sixties and the nineties, ten years after this century, are still the same, but the counterfeiting technology is changing with each passing day. Not to mention the local quality supervision bureaus and entry-exit inspection and quarantine bureaus, which are the most authoritative appraisal institutions in China, Qinhuangdao Entry-Exit Inspection and Quarantine Bureau can't say that it is 100% sure about the fraud of some honey. It also needs constant technical updates and imports more and more advanced testing equipment from abroad. You said, it's funny that you used the method of earth blast furnace ironmaking to identify honey. It's rude of you to insult the IQ of counterfeiters so blatantly.
Do you think there is really nothing you can do about fake honey? I told you, something like that. However, there are still some tricks to buy, such as the proliferation of fake honey in supermarkets and pharmacies, and more real honey in specialty stores, but all of them are concentrated honey, while only two or three companies in China are naturally mature honey.
Others asked, are these methods really useless?
Of course it works, it depends on who uses it and how it is used! You only know a little about honey and have no experience, so it is too optimistic for you to identify fake honey by these methods. But these methods can be used as auxiliary means for honey buyers, researchers and beekeepers who have been keeping bees for many years-just auxiliary means.
Maltose: white crystal, soluble in water and sweet (not as good as sucrose).
