How long does honey go bad How long does honey expire to go bad

Yes.

Honey has an expiration date, and it will expire and deteriorate.

If the honey has expired or has gone bad. In this case, the honey often crystallizes, and some of it may become sour or bubbling, so it is not recommended to eat it at this time.

Because expired honey may breed bacteria, it may cause germs to invade the intestines after eating, resulting in abdominal pain, diarrhea and other symptoms; In addition, the nutritional value of expired honey is gone. Therefore, it is recommended that honey be consumed within the expiration date.

Consumers buy honey often due to various reasons can not be eaten in time, a long time to forget, sometimes forget is several years, it seems that the honey is still good, but has long passed the expiration date, so to ask: this long-term honey can still be eaten? Scientific research and practice have proven that honey has strong antibacterial ability and is the only food in the world that does not spoil.

In 1913, American archaeologists found a jar of honey in the ancient tombs of the pyramids in Egypt, which was identified as having lasted for more than 3,300 years, but it has not deteriorated at all and is still edible. It can be seen that truly mature honey is completely edible after a long time, and there is no strict shelf life, but as a food market, according to the "Food Law", the shelf life is required to be marked on the food commodity, so honey manufacturers generally set the shelf life of honey at 2 years. However, it must be pointed out that if it is not mature honey or inferior products such as water, these honeys will ferment and bubble, become sour, and become inedible after a long time.

Of course, if the fermentation is not serious, it can still be eaten after heating in a water bath for half an hour at about 60. In short, no matter what kind of honey it is, and no matter how long it has been preserved, as long as it has not deteriorated, it is edible and will not be harmful to the body. It's just that long-aged honey has a slightly worse nutritional value than fresh honey.

It will deteriorate over time. Honey contains glucose, fructose, proteins, enzymes, vitamins (2, 6, etc.) and a variety of minerals. Fresh raw honey is viscous and transparent, and begins to crystallize and harden over time; Therefore, processed honey should be used both from a taste and nutritional point of view.

To tell if honey has been processed, you can put a spoon in and stir it, then pick it up and observe that the raw honey will drip off the spoon and the processed honey will stick to the spoon like a rubber strip. Honey will naturally "saccharify" after a long time, but it will not deteriorate because of this, and this thickening only means that honey ***. The color of honey is also varied, ranging from bright yellow (acacia) to dark brown (buckwheat), and some are green; The colour, taste and aroma of honey vary depending on the time and place of collection.

Generally speaking, the dark color of honey contains several times more minerals such as iron and copper than others. Storage of Honey Honey has many benefits, but it can easily absorb the smell of the surrounding area, so if you store honey with cheese, fish, dried cucumbers, etc., the honey will lose its original smell after a while. The best utensils for storing honey are glass jars or clay pots, and in any case tin cans should not be used.

If you want to melt the crystallized honey, you can put the honey jar in a pot of boiling water and heat it, and do not put the honey directly on the fire to grill. It is worth noting that when honey is heated to 37 -40, it loses its efficacy, so be careful not to overheat. There is a proverb called "drinking honey for a long time, you will not get disease", insisting on long-term consumption of honey is the best choice to get rid of diseases and strengthen the body.

Honey should be stored at a low temperature and away from light. Since honey is a weakly acidic liquid, it can react chemically with metals, and chemical reactions will occur when it comes into contact with metals such as lead, zinc, and iron during storage. Therefore, non-metallic containers such as ceramics, glass bottles, non-toxic plastic drums and other containers should be used to store honey.

If you have natural honey, it should be about 8 months If you are in the refrigerator for a long time, but the things stored in the refrigerator can also be broken, I remember that there is a bacteria that survives in the refrigerator, so I usually pay attention to it! I don't eat things that have been put for a long time. ^_

Ripe honey does not spoil Honey Fresh ripe honey is a transparent or translucent gelatinous viscous liquid, sugar accounts for more than 3 4 of the total amount of honey, the moisture content is low, and bacteria and yeasts cannot survive in honey. In addition, bacteriostats are also contained in honey.

It turns out that honey does not spoil and can last for 3,300 years!

The longer the honey is left at room temperature, the better

The shelf life of honey is currently 18 months for bottled honey. However, bees with high cap maturity concentrations can also last for many years. However, it is better to eat fresh honey, because fresh honey generally has a better color, aroma and taste.

Honey turns white and precipitates into glucose crystals, which will not deteriorate, and the taste quality will not change, and it will not affect normal consumption. Honey is a weakly acidic substance that reacts weakly with metals, so it should be stored in a non-metallic container (such as glass or plastic drums). Generally, the shelf life of high-quality honey is five years.

How honey is preserved

Honey can be sealed and stored at room temperature, and the honey will be placed at room temperature for a long time, without mildew or qualitative change, the main reason is that honey has a strong antibacterial effect on various bacteria. Honey contains antioxidants, but also because it is acidic and has a high sugar content, it maintains a high penetration power, and microorganisms cannot survive in this environment.

In addition, honey is a weakly acidic substance, and the container for storing pure honey is best glass or ceramic utensils, not metal utensils such as iron and lead, so as not to contaminate the honey with free heavy metals. Honey stored in non-toxic plastic bottles should not be too long. Honey packed in containers is best sealed with a lid and protected from contact with moist air to avoid fermentation.

It should be kept in a clean, cool and ventilated place, and it is best to keep the honey in the refrigerator, taking care to avoid contamination.

Honey actually has a deterioration phenomenon.

When the moisture in the honey is too high, too much water will form an environment conducive to the survival of yeast, and the yeast will multiply in large numbers under suitable conditions, and constantly decompose glucose and fructose in the honey in the process of reproduction, as its own nutrients, and produce a certain amount of carbon dioxide and alcohol, and the honey will appear a thick layer of bubbles, which smells of putrid sourness and alcohol, and then the honey will deteriorate. It is not recommended to eat the spoiled honey field bees, which contain a large number of microorganisms and can easily cause discomfort such as vomiting and diarrhea.
