Raw natural honey has strong antibacterial ability, which can inhibit the growth and development of microorganisms. Glucose in honey produces antibacterial substance-hydrogen peroxide under the action of oxidase, which easily decomposes oxygen at high temperature, making a layer of white bubbles appear on the surface of honey. Raw honey contains a lot of active substances, and active enzymes can also promote honey foaming.

Honey also has after-ripening. There is always a layer of white dog on the surface of the honey just taken from the honey bucket. The brewed and freshly taken honey is constantly changing inside the honey, and the brewing activity is still slowly going on. In this process, tiny bubbles will appear in honey. These bubbles will float on the surface of honey, forming a fine white foam.

Identification method of true and false honey:

1, depending on gloss and viscosity.

Distinguish between true and false honey depends first on luster and viscosity. Good honey is clear and bright as oil. When you shake the honey bottle, the vibration is very small. After stopping shaking, the honey hanging on the bottle wall will slowly flow down.

2. Invert the honey bottle.

High-quality honey has low water content and sticky texture. If the sealed honey bottle is turned upside down, it will be found that the air sealed at the bottle mouth is difficult to float bubbles.

3. pull "honey silk".

Stir some honey with a spoon or toothpick, and lick it. Real honey can usually pull out thin and translucent "honey filaments", which will automatically retract after being broken, showing a spherical shape.

4. Abrasive particles.

If you buy natural "crystal honey" that is milky white or light yellow, you can pick out a small part of the crystal and grind it at your fingertips. The crystal particles of true honey are very fine and will completely melt.

5. Try it.

Honey tastes like honey and sugar tastes like sugar. Pure honey is sweet and slightly sour, with a soft and delicate taste, while fake honey has a light taste and a short aftertaste.

6. Shelf life.

Natural honey can be preserved in a sealed state in the natural environment for a long time without deterioration. If the bought honey goes bad in the unopened state, it must be artificially mixed with other ingredients.
