How long can honey last before it expires, and how long can honey last without expiration

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.

The shelf life of honey on the market is generally 18 months or 2 years, but in fact, well-preserved honey has no fixed shelf life, because the water content of mature honey is less than 20%, and it contains acidic substances and high concentration of sugars, so it can inhibit the growth and reproduction of a variety of bacteria, and the storage time is longer.

Strictly speaking, pure honey has no expiration date.

Honey contains almost no water, and the extremely high concentration makes it impossible for bacteria to survive and replicate in honey, so real pure honey is preserved well and will hardly deteriorate, even if it is stored for hundreds of years, it will not expire.

However, under normal circumstances, the honey purchased by patients in major supermarkets is non-natural honey that has been artificially processed, so it can be stored for about one and a half to two years if it is stored in a cool and dark place at room temperature.

The shelf life of honey depends on the environment in which you store it, in general, honey can be stored for 18 months, but different storage environments have different shelf life.

How to preserve honey:

1. Sealed preservation: When choosing honey, you can choose a small can, if you buy a large can, then buy a roll of plastic wrap and cover the lid first after eating each time, and then wrap the bottle mouth with plastic wrap.

2. Heating to prevent fermentation: In the hot summer, honey is easy to ferment at room temperature, and if you find this situation, you should put the honey in a glass container, put it in a pot and heat it to 63 pants Sakura 65, and keep it warm for 30 minutes to stop fermentation.

3. Anti-deterioration of ginger slices: To make the honey not deteriorate and taste for a long time, you can put an appropriate amount of ginger slices in the honey.

Honey selection method:

1. Smell the smell.

The formation of honey is inseparable from flowers, so honey must have a floral fragrance, because of the different sources of honey, each honey also has its own unique taste, in general, high-quality natural honey will have a light floral fragrance, and it is pure and single.

If it smells pungent or the floral fragrance is too strong, it means that there are other added ingredients in the honey and it is not pure honey; Secondly, if you smell alcohol, or other peculiar smells, it means that the honey has deteriorated, and it is recommended not to eat it again.

2. Look at the drawing.

Most of the honey has the characteristics of drawing, we can't see it before buying, but after buying home, we can pick up the honey with chopsticks to observe whether the honey is drawn, so as to judge the quality of the honey.

When the silk is broken, the honey can also be retracted to form beads, while the adulterated honey is provoked, either it can't be picked up, or it can't be picked up and can't be picked up.

The shelf life of honey is generally 18 months or 2 years, but if the fruit is well preserved, the shelf life of honey usually exceeds the shelf life.

At present, the best honey on the market basically has a shelf life of 2-3 years. In general, the purity of farm-brewed honey is, the longer its shelf life. But in the process of eating, it is easy to cross-contaminate food.

Bacteria and mixtures are mixed into the honey, and the honey is prone to fermentation and spoilage. Therefore, no matter what kind of honey it is, it is best not to store it for too long.

The sugars in honey are broken down into ethanol, acetic acid and water, carbon dioxide, etc., which is what causes honey to spoil. So under normal circumstances, the concentration of honey decreases after spoilage, and the liquid becomes thinner, accompanied by a large number of bubbles. You can try it lightly.

If it feels sour, it means that the honey has gone bad.

How to preserve honey:

The best way to store honey is to store it at room temperature in an airtight container. First of all, it is better to choose glass and ceramic products for containers, because there are some enzymes or acidic substances in honey, and if iron is used, it is easy to have chemical reactions, which will affect the quality of honey and some nutrients; Secondly, it should be sealed, and it will not react with air and water after sealing.

When storing honey at room temperature, be sure to protect it from light and choose a cool, dry and ventilated place, so that the storage time will be longer. If the honey becomes thinner, has a lot of bubbles, and the taste becomes sour, there are health risks and can no longer be eaten.
