Look: Pure honey is a viscous colloidal liquid, bright and moist. All kinds of honey have a fixed color. For example, linden honey is light amber, clear and bright, sunflower honey is amber, and the color of mixed nectar is not fixed, usually yellow-red. Stir the honey with chopsticks several times. When you lift chopsticks, you can see that pure honey is bright and transparent in bright places, while adulterated honey is turbid. True honey has strong light transmittance and uniform color; Inferior honey is turbid and has impurities. The new honey is light amber and transparent. Honey is brewed with boiling water, and it is good to dissolve without precipitation; Inferior honey is not easy to dissolve and has precipitation.

Smell: Real honey is sweet, while fake honey has no smell. Honey mixed with spices has an unusual smell. Real honey can give off a unique honey fragrance a few months after harvest, which is rich and lasting, and can be smelled when opened; Or put a little honey in your palm and rub it to smell it. It has a charming honey smell.

Taste: high-quality honey is sweet and has a long aftertaste. Adulterated honey has no floral fragrance, some fake honey has the taste of boiled sugar, and the fine products have the taste of white sugar water. Pure honey will melt quickly and have a strong floral fragrance; Adulterated honey crystals are not easy to dissolve at the entrance and have an odor. Honey is refreshing and sweet, and never stings the throat.

Chemical examination: the color of the iodine solution of honey mixed with starch will turn blue, and the honey mixed with maltose will appear white floc when the concentration of ethanol is increased. Honey mixed with other impurities is inserted into honey with red-hot iron wire, and there is a sticky substance on the iron wire.

Cryopreservation crystallization test: Honey will become solid after being stored for a period of time at 4 to 14 degrees Celsius, which is a physical phenomenon of honey. The real honey crystal has poor transparency, soft crystal layer and no sand feeling when twisted with fingers. Crystal is so soft that fake honey can't penetrate it. Real honey will melt quickly when pinched by hand. False honey has the feeling of hurting hands, and it melts slowly or does not dissolve. The real honey crystal has a low bite, while the fake honey crystal is crisp and loud.

In addition, pure honey is not easy to seep out when dripping on white paper, while honey mixed with water will seep out slowly. Pure honey has high concentration and slow flow. Drop a drop of honey on paper, and high-quality honey will be beaded and not easy to spread; Inferior honey is not beaded and easy to spread.

Of all the methods, I usually use chopsticks to pick up the last one. For the supermarket to buy honey, you can probably only recognize the brand, because fakes are very similar now. What brand to buy? Go back and try the above method. If it is good, just buy it next time.

In addition, it is best not to put honey in a glass container, which is easier to ferment.
