First of all, if you buy pure honey without any artificial addition and processing, it is difficult to deteriorate. If it is well sealed and stored in a proper environment, it will hardly deteriorate, and it can continue to be eaten after three years.

However, if the storage is unfavorable, such as being placed in a humid environment for a long time, being exposed to the sun for a long time, or the seal is not in place. In this case, even pure honey will go bad.

Skills of judging whether honey has gone bad

In general, honey often produces a strong smell after deterioration, which smells like fermented vinegar or alcohol. The reason for this is that honey contains a certain amount of yeast, which will decompose the sugar in honey, make the original floral fragrance disappear, and then produce sour taste or wine taste, indicating that honey has gone bad.

Besides distinguishing honey by smell, we can also observe the texture of honey. If honey goes bad, it often becomes a little thin instead of thick. In addition, some flocs may adhere to its surface, become turbid and produce foam-like substances, which make the bottle swell and the surface moldy. Once these changes happen, it is not suitable to continue eating.
