Chemical test: the color of honey mixed with starch will turn blue when added to iodine solution, white flocculent matter appears after honey mixed with starch syrup is added to high concentration ethanol, honey mixed with other impurities, inserted into honey with red-hot iron wire, and sticky matter is attached to the wire.
Refrigerated crystallization test: Honey becomes solid after being stored at 4 to 14 degrees Celsius for a period of time, which is a physical phenomenon of honey. The crystals of real honey are pricked with chopsticks, which is very soft, and fake honey cannot be pierced.
Real honey is pinched by hand, and its crystals dissolve quickly, while fake honey has the feeling of being awkward, and it dissolves slowly or does not dissolve. Real honey crystals bite with teeth with a low sound, while fake honey crystals are crisp and loud. After pouring out the honey and waiting for it to solidify slightly, if it is genuine, the honey will form a hexagonal structure like a honeycomb, but the fake one does not.

Smell it with your nose, it can't be a particularly sweet one, the kind is doped with white sugar.

Yes, real honey has a floral flavor.

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 will be sugary.
Seven taste identification: real honey is sweet and delicious, with a slight sour taste, the crystalline block is crispy when it enters the teeth, and it melts when it is contained, while the fake honey has a bitter and astringent taste, and the crystalline block chews like sugar, and the sound is crisp and loud.
Eight smell taste identification: real honey has a faint plant flavor and floral aroma, and fake honey smells pungent or fruit candy.
Nine crystallization identification: fake honey is not crystallized, but the white sugar added to some fake honey will also precipitate under certain conditions and form a precipitate at the bottom of the bottle. The crystallization of real honey and the precipitation of fake honey are easy to distinguish, and the crystals of honey are relatively soft, and they can be easily twisted on the fingers, and there is a delicate feeling.
The white sugar precipitation precipitated by fake honey is relatively dense, and when it is twisted on the finger, it has a gritty feeling.

Aroma: Real honey can exude a unique honey fragrance a few months after harvesting, fragrant and long-lasting, and can be smelled when the bottle is opened; Or put a little honey in the palm of your hand, rub it and smell it, there is a fascinating honey fragrance.

Bees distinguish taste through their sense of smell, and bees have a sensitive sense of smell and are able to identify bees in the outer colony based on smell. There are often bees guarding the gate of the nest to prevent the bees from entering the nest casually. When there is a shortage of honey sources, bees that are not from the swarm often sneak into the nest to steal honey, and the guard bees immediately fight.
But outside the hive, the situation is different, such as in the spring flowers or in the drinking place, where different groups of bees are together, not hostile to each other, and do not interfere with each other.
Bees are social insects that are made up of individuals such as queen bees, drones, worker bees, etc. Bees are one of the beneficial insect groups for humans, and are often broadly referred to as production bee species: the Western honey bee and the Chinese honey bee.
It pollinates crops, fruit trees, vegetables, pastures, camellia crops and traditional Chinese medicine plants, and the yield can be increased by several times to 20 times.
-
Real honey is viscous, liquid can be seen when provoked, flexible filaments, continuous flow, fake honey has suspended solids or precipitation, small viscosity, droplets, droplets, drops, and broken flow when provoked.
