Honey claims to have no expiration date, why is the shelf life of honey sold in supermarkets marked

Human consumption of honey has a long history, is the quality of food provided by nature**, the highest shelf life found so far is found in the pyramids of Egypt, is still well preserved, enough to show that honey is very shelf-stable food. But in fact, in life, if you go to the supermarket to buy honey, you will see that the bottle is marked with the expiration date, and most of them are in 1 and a half to 2 years, which is obviously contradictory to the indefinite preservation of honey, so can honey be stored indefinitely?

The reason why honey can be stored for a long time is mainly because the sugar content in honey is very high, including glucose and fructose, reaching more than 80%, in such a high sugar concentration, most of the bacteria can not survive, so honey can be stored for a long time, which is similar to the usual liquor, salt and other foods. However, the actual situation of honey is more complicated, now the honey on the market is mainly honey, that is, honey that has not been fully brewed by bees, which has a higher water content and is very similar to nectar, so it can not achieve long-term preservation, and now the beekeeping technology is quite mature, if there is sufficient flower source, the amount of honey produced is still very high, so these honey ** in the supermarket is relatively low.

Honey can indeed be preserved indefinitely, but this is only for mature honey, mature honey is bees after collecting nectar, and then mixed with bee secretions to fully brew, these honey can be preserved well, indeed the shelf life is very long, but this honey is produced for a long time, for beekeepers are not cost-effective. The yield of mature honey is very small, ** can reach two or three hundred yuan 1 catty, many ordinary consumers can not afford it, so there is no market, and the ordinary honey production is very high, the unit price is about 20 yuan 1 catty, many people buy for reasons, ** also meets the demand, because the nutritional value is indeed not much different, so now the vast majority of honey on the market is honey.

Which one to buy is mainly up to the individual's own considerations, but it is best not to buy fake honey. Now fake honey is mainly divided into two kinds, one is alum brown sugar water, brown sugar, alum and other raw materials are fully mixed, in appearance and color and honey is very similar, as cheap honey sold, deceived many people in the past, but now through many means can be identified, including paper dipping method, check the dripping honey form, smell and so on can be identified, so basically can not be seen.

The shelf life of naturally ripened honey is very long, and honey contains a large amount of fructose, which is in a state of high osmotic pressure, making it difficult for external bacteria and germs to invade. However, when consuming honey in actual life, due to the continuous opening and repeated use of spoon immersion, it will lead to an increase in water vapor in honey, a decrease in osmotic pressure, and an increase in bacteria, so honey still has a shelf life in actual consumption.

Because what supermarkets sell is artificially added, it is not pure honey.

Things that enter the supermarket must have an expiration date, otherwise they will become three-no products.

It should be the industrial and commercial bureau that requires that all goods must have a shelf life mark.

Because in the past, honey was without preservatives, and now it is bought in supermarkets with preservatives.

You can see everything you buy in the supermarket, so if you don't add one, you will definitely be able to drink it.

Things in the supermarket have no expiration date, and they are not allowed to be sold.

In other words, I want to prove that I can go in and out of the supermarket openly.

Isn't it a three-no product if there is no expiration date, so there must be a shelf life.

A lot of the honey bought in the supermarket was added by the roommate, so he had a limited time.

Honey does not have a shelf life in the strict sense, the reason is that the osmotic pressure of honey itself is very high, and honey contains a large number of natural antibacterial ingredients, so the natural honey that is completely matured by bees actually has no shelf life, but if the quality of honey is too poor, it is easy to deteriorate in advance, for example, the concentrated honey artificially concentrated with immature honey with super high water content has a strict shelf life.

Although honey does not have a shelf life, it must be marked as a food with a shelf life, so the shelf life of honey is generally marked as 2 years or 18 months, but it does not mean that honey will deteriorate after expiration, in fact, honey expiration and deterioration are completely different things, if it is stored at the time, even if it expires, it will not deteriorate, and some natural mature honey can be put for several years or even more than ten years without deterioration after being completely sealed.

Because wild honey can be stored for a long time, even if it is left for a few years. And its nutritional value does not change, it is a food that can be stored for a long time and will not spoil.

Because many people think that bees can still eat as long as they do not spoil their taste, they think that they will not be bad, and they will eat as long as they can eat them, so there is no expiration date, as long as they are not bad, they will eat them.

This is because people generally eat honey in a short period of time after buying it, and there is no particularly serious difference between spoilage or non-spoilage.

This is real honey that actually has good preservation, and will only become thicker and thicker over time, in fact, it only crystallizes, not deteriorates. Therefore, there is no such thing as expiration.

Because some people think that honey will be purer the longer it ages, it will not expire at all. They also think that the bees are eating honey and that it is impossible to eat all the honey in a year, so they think that it is a lie to say that it is expired.

Because pure honey contains very little water and honey has an antibacterial effect, real pure honey is theoretically never bad.

This sentence is correct, because after a year, the nutrients in it will decline, and there will be no good effect, so generally speaking, it is not suitable to eat after a year.

This statement is incorrect. For honey without sterilization process, the shelf life will be very short, up to half a year, it is generally recommended to eat the honey as soon as possible after opening, so as not to affect the nutrients in it for a long time, and drink some honey appropriately in life, which can not only play the role of laxative, but also play a role in beauty and beauty.

I don't think it's correct, because my honey seems to have been stored for a long time and has not been used up, maybe the best time to use honey is within a year, but if you keep it properly, it should be a little longer.

I think this statement is true, because a lot of honey on the market is processed, so it will expire quickly.

The plan is definitely correct, because there will be some trace elements in honey, and honey is relatively moist, and it is also some ingredients with a relatively high sugar content, if it is left for too long, it will be easy to breed some bacteria, and the nutrients in it will slowly decrease over time.

Honey has a shelf life, and the normal shelf life of honey will be around two years.

If it is pure honey, the shelf life will be longer. If the honey has expired, it should not be drunk, because the expired honey contains nutrients that have been destroyed, and may breed pathogens, which can easily lead to intestinal inflammation after eating, causing abdominal pain, diarrhea and other symptoms.

Honey, also known as sweet honey, is susceptible to contamination with botulinum toxin and is a supersaturated solution of honey and sugar made by bees. It crystallizes at low temperatures. It is glucose that produces crystals, and the part that does not crystallize is mainly fructose.

Benefits of consuming honey in moderation:

1. Honey can promote the secretion of gastric juice in the gastrointestinal tract, so as to achieve a regulatory effect, and can play a role in regulating the spleen and stomach for people with spleen and stomach disharmony.

2. Honey is rich in glucose, fructose and other substances, which are easily absorbed by the human body, and the consumption of honey can quickly replenish the body's energy, and has the effect of moistening the intestines and laxatives, especially for intestinal dryness and constipation, the elderly constipation has a certain relieving effect, and the moderate consumption of honey has a good relieving effect.

3. Honey has the effect of anti-inflammatory, antibacterial and scalding. When there are small burns or small wounds on the body, applying a little honey has a good effect on relieving pain and reducing inflammation.

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

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.

Summary. Honey has strong hygroscopicity, can absorb water from the air, once absorbing too much water will make the water activity rise, plus the presence of yeast in honey (generally honey will exist some, the concentration will not multiply under the condition of relatively high concentration), when the temperature and humidity are suitable, the yeast will grow and multiply rapidly, so that the honey ferments, becomes sour and flatulent. In addition to moisture absorption, honey also absorbs odors from the air if the container in which the honey is stored is not properly sealed.

Hello! The disassembled honey is best stored in a cool and dry place, and in general, the honey that exceeds the shelf life of honey stipulated in China's food law is 18-24 months, and it is best to throw it away if it has not been eaten. Don't be reluctant, otherwise you will be hurt by eating.

Shelf life refers to the quality assurance period of the product under the specified storage conditions.

Honey is a supersaturated solution of sugar, with a high sugar concentration and high permeability, so honey itself has strong antibacterial and anti-corrosion capabilities.

The natural floral flavor and active enzymes in honey will be greatly reduced with the extension of storage time.

Honey has a strong moisture absorption, can absorb water from the air, once absorbing too much water will make the water activity rise, plus the presence of yeast in honey (generally honey will exist some, the concentration will not reproduce under the condition of relatively high concentration), when the temperature and humidity are suitable, the yeast will grow and multiply rapidly, so that the honey ferments, becomes sour and flatulent. In addition to moisture absorption, honey can also absorb odors from the air if the container in which the honey is stored is not properly sealed.

Honey is also weakly acidic, and if it is stored in a metal container, it is easy to react with metals during the storage process, resulting in heavy metal pollution in honey. Therefore, it is best to use ceramic, glass bottles, and non-toxic plastic bottles for storage.

Honey is a natural nutritious food, in fact, most foods have a shelf life, beyond this period may spoil, but honey is a very special food, so honey has an expiration date?

1. There is no so-called strict shelf life of real and innocent honey, and it may not be bad for hundreds of years if it is well preserved, and the general merchants set the shelf life of honey at 2 years or 18 months.

2. 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 the shelf life.

3. Therefore, 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 in the pyramid in 1913 3300 years ago has not deteriorated at all.

That's it for the introduction of whether honey has an expiration date.

Summary. The shelf life of honey on the market is generally 18 months or 2 years. China's food safety law clearly stipulates that except for salt, solid sugar, soy sauce and high-strength wine, if the food does not have a specific shelf life, the shelf life shall not exceed 2 years.

But if it is well preserved, honey usually lasts well beyond its shelf life. Of course, the shelf life of honey is closely related to the quality of the honey and the preservation conditions. Honey contains acidic substances and high concentration of sugars, which has a strong bactericidal effect and can inhibit the growth and reproduction of a variety of bacteria, so honey can be stored for a long time.

If the honey is immature, it will be stored for a shorter time. At the same time, the storage conditions are also very important, because honey has strong water absorption, when honey contains more than 21% water, it provides favorable conditions for the survival of yeast, and honey will ferment and deteriorate in case of improper storage. It is recommended that honey must be sealed and stored in a cool and dry place after purchase, and protected from direct sunlight and high temperatures.
