How long can honey be left out after adding water, and how long can honey be placed

Honey generally has a shelf life of 18 months or 2 years, but if it is well stored, honey usually lasts well beyond its shelf life. La Qiqing.

Honey is the nectar or secretion of plants collected by bees, which is fully brewed, pure honey is fully brewed for 7 to 15 days, and the water content is generally less than 20%, and the natural preservation time is longer.

Honey can be stored foreverHowever, it is necessary to store ripe honey, sealed, corrosion-resistant containers (non-metallic), and cool places.

Honey is a food that does not spoil easily, and this has been clearly explained in science. Since honey has less water, generally about 20%, and the sugar content is high, generally 80%, forming an environment called "high osmolarity" in technical terms, and microorganisms cannot multiply. Moreover, honey contains a large number of active enzymes, which has strong antibacterial and sterilization functions.

Therefore, honey does have strong antimicrobial ability and can be stored permanently without the addition of preservatives, but in fact, this theory is feasible but difficult to implement on a daily basis.

Although honey is very resistant to storage, due to the presence of osmophilic yeast, it is necessary to pay attention to the storage conditions when storing honey in daily life. The preferred temperature for osmophilic yeast is 25-37 degrees Celsius, so honey should be kept in a cool, ventilated and dark place that can be refrigerated.

It is normal for honey to produce white crystals when refrigerated, which is a physical change, and the composition of the honey itself does not change, so it can be eaten with confidence.

In addition, honey storage needs to be sealed against moisture, minimize contact with the air, and do not use a spoon with water when handling honey.

The above content reference: People's Daily Online-How can honey still have an expiration date?

A year or so. It is necessary to put the honey in a low temperature and dry place, which is more conducive to the long-term preservation of the honey.

Unopened honey can be left out for two years, and honey can be left open for one year.

After a large number of studies, it has been proved that honey has relatively good antibacterial ability and is generally not prone to spoilage. However, most of the honey on the market today is not pure honey because it has other additives added, so it also has a shelf life. After the expiration date, honey generally becomes sour, ferments and bubbles, in which case the honey cannot be consumed.

Honey can generally be stored for about two years.

Honey can be said to have a shelf life, it can also be said that there is no shelf life, there is a shelf life because the honey sold on the market is basically concentrated honey or processed honey, in fact, the shelf life of these honeys is very short, and according to the relevant laws and regulations of the country, food must be marked with a shelf life, so the shelf life is generally marked as 2 years, and there is no shelf life because the real mature honey can be preserved for a long time as long as it is preserved, and the honey excavated 3300 years ago in the pyramid in 1913 has not deteriorated at all.

There are three main reasons why honey has a long shelf life:One is that honey is a supersaturated solution of sugar, and the osmotic pressure inside is very large, and it is difficult for most microorganisms to survive in such an environment.

The second is that the acidic environment of honey is not suitable for microorganisms.

Third, honey itself also contains a certain amount of antibacterial substances that can inhibit the growth of microorganisms, of course, the premise must be natural mature honey, it is worth noting that honey is most afraid of yeast, if it is not stored properly and is contaminated by yeast, it will soon ferment and deteriorate.

Real honey has no expiration date and can be stored all the time without spoilage, but it needs to be stored at a low temperature, preferably in the refrigerator, and it can be stored forever.
