How do you know if honey has gone bad?

Scientific studies have proven that honey does not expire, and it is the only food known not to spoil! The premise is that you want to confirm that you are not buying fake honey.

The honey smells of wine and is spoiled.

Ways to tell if honey has gone bad:

First, the texture becomes thinner.

Thinning of the texture is the main characteristic of honey spoilage, the reason is that the main culprit of honey deterioration is the proliferation of microorganisms, especially yeast, can not only decompose the sugar in honey, but also accompanied by the generation of a large amount of water in the decomposition process, so the texture of honey will become thinner and thinner with the degree of deterioration, and some honey with serious deterioration may even become as clear as water.

Second, the taste becomes sour.

Sour taste is an important feature of honey deterioration, although honey (pH value 3 4) itself is a slightly sour food, but in fact the sour taste of honey is not obvious, if there is obvious sourness, it is mostly spoiled, because yeast can decompose sugar into ethanol (alcohol), ethanol is reductive and can be oxidized to form acetic acid (acetic acid), so honey often has a very obvious sour taste after spoiling.

3. It smells of alcohol.

Alcoholic taste is an important feature of honey deterioration, the reason is also that yeast will decompose sugar into alcohol, and the stronger the alcohol taste, the more serious the degree of deterioration, it is worth noting that honey will have an alcoholic taste after a long time, as long as the alcohol taste is not obvious, you can continue to eat, but there is a strong alcoholic taste, it means that it has been seriously deteriorated, and if you continue to eat at this time, it may have adverse effects on health.

Fourth, a large number of bubbles.

It is normal for honey to have a small amount of bubbles, because the invertase enzyme in honey has been active, and it is still converting the polysaccharides in honey into monosaccharides, and at the same time generating a small amount of gas and producing a small amount of bubbles, especially in new honey, this phenomenon will be particularly obvious, but a large number of bubbles is a manifestation of honey deterioration, these bubbles are carbon dioxide produced by yeast when they break down sugar.

Summary: Honey deterioration is basically caused by the proliferation of yeast, so the characteristics of honey deterioration are related to yeast metabolites, such as yeast decomposes sugars to form ethanol to make honey have a wine taste, and ethanol oxidation to produce acetic acid makes honey have a distinct sour taste.

For the first time, you can smell the taste, the spoiled honey has a large number of yeasts, these yeasts will continue to decompose the sugar in the honey, produce alcohol and acetic acid, destroy the original floral flavor of the honey, such honey will have a very strong wine and vinegar flavor.

The second is to look at the appearance, the texture of high-quality honey is more viscous, but after spoiled honey, there is more moisture in it, and the texture of honey is thinner, and some flocculent substances will appear. In addition, carbon dioxide will be produced inside the honey after it deteriorates, so a thick layer of foam will appear on the surface, and if the honey is bottled in a plastic bottle, there will be a phenomenon of swelling of the bottle. If you take a closer look, you can accurately tell whether the honey has gone bad or not.

After spoilage, you should not continue to eat honey, because a large number of bacteria and microorganisms have grown in it, and continuing to eat it may have a certain impact on your health and be prone to diarrhea. For the sake of everyone's health, don't continue to consume this honey.

Appearance: The normal texture of honey is viscous, it is a thick liquid substance, but after deterioration, the texture will become thinner, and flocculent will appear, and at the same time, there will be a thick layer of foam due to the production of carbon dioxide, and the appearance is easier to distinguish. Smell:

Normal honey tastes fragrant with a sweet aroma peculiar to honey, while spoiled honey has a pronounced wine and sour taste, which is caused by the fermentation of honey.

It is relatively easy to determine whether honey has deteriorated by observing the state of color, taste, shaking and hot water.

01 Look at the color.

If you look closely at the color of the honey, if it is severely bubbly and obviously cloudy, it means that the honey has gone bad and is not edible.

02 Smell the smell.

Open the jar and smell it, if there is a sour smell after fermentation, it means that it is seriously deteriorated and not suitable for consumption.

03 Shake to observe the state.

Close the lid tightly and shake it vigorously to see if the honey is in a runny or sticky state, if it is watery, it means that it has gone bad.

04 Distinguish with hot water.

Put a small spoonful of honey directly into the glass, add more than 4 times the hot water, let it melt, and let it stand for about three hours, if there is no sediment, it means that the quality is excellent.

05 Blank paper identification.

If you put a few drops of honey directly on top of the white paper, it is viscous and does not flow quickly, which means that the honey is of good quality.

The key to distinguishing the spoilage of honey is the taste, the spoiled honey will have an alcoholic smell, while pure honey is the fragrance of the nectar source plant, so you can smell it.

Tell that the honey has deteriorated, the taste becomes more sour, and it becomes very thin. Honey is a natural sweet substance that bees harvest from the flowers of flowering plants and are fully brewed in the hive. The smell is fragrant and rich, and the taste is innocent and sweet.

Honey is a supersaturated solution of sugar, which crystallizes at low temperatures, and it is glucose that produces crystals, and the part that does not crystallize is mainly fructose.
