There is a thick layer of white bubbles on the surface of honey, and it smells of alcohol and a bit of rancid sourness.

Because there are yeasts in honey, under the action of temperature and water, they will cause the honey to undergo a fermentation reaction, and the taste of the honey will also become sour.

In addition, the texture of some honey will become very thin after deterioration. In the most severe cases, it will behave like water, and there will be a layer of bubbles on the surface of the honey.

The appearance of deterioration is as follows:

Introduction to honey

Real unprocessed honey will have a large number of bubbles in the honey after shaking in summer, making the honey It is easy for the honey to swell out of the bottle and form a layer of white bubbles on the surface of the honey. But after letting it sit for a few hours, the bubbles will disappear automatically, and gas will burst out when you open the honey bottle! (The highest temperature in honey is 43 degrees, and honey will have very obvious bubbles when shaken at room temperature), but as long as the temperature drops in autumn, this phenomenon will disappear!

This is related to the fermentation of honey. Difference: Common water honey, such as 1-day-old honey, has a high water content. In addition to bubbles, honey also has a strong alcoholic and pungent smell. It has become sour and fermented, and is no longer edible.
