What does honey look like when it goes bad, what does honey look like when it goes bad

After the honey deteriorates, the viscosity decreases, obviously thinned, there will be a thick layer of white bubbles on the surface, if you feel that a single method is not at ease, it is recommended that you smell the taste at the same time, the spoiled honey has lost its original aromatic smell, open the bottle where the honey is stored, there will be an obvious smell of alcohol, mixed with a kind of food rotten sour smell, the smell is very pungent.

The spoilage of honey is due to yeast. Mature honey contains acidic substances and high concentration of sugars, has strong antibacterial properties, water content is relatively low, and the storage time is generally longer, but when the water content in honey is higher than 21%, it will provide a favorable environment for the survival and reproduction of yeast, and under suitable circumstances, a large number of yeast growth and reproduction will destroy the nutrients and sugars in the honey, so carbon dioxide and alcohol are produced, and the honey begins to ferment.

In daily life, people often keep honey in the refrigerator, but for honey, the texture of the product changes when it is refrigerated. After being stored in the refrigerator for a while, the honey crystallizes and hardens and thickens. Although this change does not affect the safety of honey or its nutritional value, it will affect the taste to a certain extent.

Therefore, honey does not have to be refrigerated.

Honey deterioration has an obvious feature, that is, a thick layer of white bubbles appears on the surface, which is due to the process of honey spoilage and fermentation, yeast constantly decompose the glucose and fructose in the honey, producing a certain amount of carbon dioxide.

There are also obvious changes in the taste of spoiled honey, the taste of unspoiled honey smells like the fragrance of the nectar source plant, light or strong, it tastes sweet and moisturizing, and the aftertaste is delicate and long, while the spoiled honey smells of alcohol and putrid sourness.

There are three types of honey spoilage, one is sour, honey spoilage is due to the decomposition of bacteria, and spoiled honey will smell and taste slightly sour. Two:

Thinning, from a sticky, hard-to-stir state, it becomes easy to stir with chopsticks. Three: Foaming, spoiled honey will also have a layer of gray bubbles on the surface.

If the honey has deteriorated, then it must not be eaten again, such honey should not be eaten even if it is processed, safety first, expired honey will ferment, you can obviously feel the sour taste, and eating it is harmful to the body.

Generally speaking, the shelf life of honey is relatively long, and if it is stored properly, it can generally last for about two years. To make the honey leave for a long time without deterioration and taste, you can put an appropriate amount of ginger slices in the honey.

The method of putting ginger slices is: choose pure and free of impurities, put it in a clean glass bottle or ceramic jar, and then add a small piece of ginger to every 500 grams of honey, seal it and store it in a cool place, so that it can be stored for a long time without deterioration.

The deterioration of honey is manifested as: thinning of the texture, sour taste, alcoholic taste, and a large number of bubbles.

1. The texture becomes thinner.

Thinning of the texture is the main characteristic of honey deterioration, the reason is that the main culprit of honey deterioration is microorganisms, microorganisms 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 severe deterioration may even become as clear as water.

2. The taste becomes sour.

Sour taste is an important characteristic of honey spoilage, although honey (pH 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 most likely spoiled.

3. It smells of alcohol.

Alcohol smell is an important feature of honey deterioration, the reason is also to 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 alcohol smell after a long time, as long as the alcohol taste is not obvious, it can still be eaten, but there is a strong alcohol flavor indicates that it has been seriously deteriorated.

4. 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 the new honey, this phenomenon will be particularly obvious, but a large number of bubbles is a manifestation of honey deterioration.

How to buy honey:

1. Observation: Real honey will thicken at low temperatures, but it will not crystallize. Whereas, honey with added sugars crystallizes easily.

2. Smell: Real honey has a natural floral fragrance and pure taste. Fake honey tends to have a pungent or unnatural taste.

3. Taste: Real honey has a smooth taste, melts in the mouth, and has a long-lasting sweetness. Fake honey may have a viscous taste, a short-lived sweetness, or a taste of chemical additives.

4. Water solubility test: take a small spoonful of honey and put it in water, the real bee rock honey will dissolve slowly, and it will sink in a spiral shape during the dissolution. Fake honey is easy to dissolve quickly and does not have a spiral sinking.

5. Flame test: Ignite honey with a match, real honey can burn and emit a yellow flame, while fake honey is difficult to burn or the flame color is abnormal.

Honey spoiled can be found from appearance, smell, texture, taste, style.

1. Appearance: Honey foaming is the most intuitive phenomenon of honey deterioration, because honey contains a kind of sugar-resistant yeast, which will multiply in large quantities under suitable conditions, resulting in a large number of bubbles in honey, and even the phenomenon of expanding the bottle when bottled in plastic bottles.

2. Smell: Honey has a strong wine flavor that has deteriorated, the reason is still the sugar-tolerant yeast in the honey, simply put, the sugar-resistant yeast will decompose the sugar in the honey into alcohol, so that the honey has a wine flavor, and with the increase of the degree of deterioration, the wine flavor will become stronger and stronger.

3. Texture: The thinning of the honey texture is a sign that the honey has deteriorated, and under normal circumstances, honey is a thick liquid, but if the texture of the honey is found to be thin, it means that it has deteriorated.

4. Lack of taste: honey souring is the most important feature of honey deterioration, because honey contains a sugar-resistant yeast, which will generate an acidic substance after decomposing sugar, so that honey has a sour taste, that is, honey has deteriorated.

5. Touch: If the honey is spoiled, it will have a rustling feeling to the touch, which is the tactile feeling caused by the deterioration of the yeast Rothalobacterium.

Flavor. Honey will have a putrid sour and alcoholic taste after spoiling, which is related to the process of spoilage.

Appearance. The appearance of the honey after spoilage will also change.

If the deterioration is severe, the bubbles will take on a thick layer, and some will appear flocculent.

The honey has a thick layer of white bubbles on its surface and smells alcoholic with a somewhat putrid sourness.

Because there are yeasts in honey, under the action of temperature and water, they will cause the honey to ferment, and the taste of the honey will also become sour.

In addition, some honey has become very thin after deterioration, and when the agitation is most severe, it will behave like water, and there is a layer of bubbles on the surface of the honey.

The appearance of the deterioration is shown below:

Introduction to Honey

Real unprocessed honey will have a large amount of bubbles in the honey after shaking in the summer, making it easy for the honey to rise out of the honey bottle and form a layer of white bubbles on the surface of the honey. But after a few hours of resting, the bubbles will disappear automatically, and when you open the honey bottle, the gas will rush out! (The highest honey at room temperature is 43 degrees, and the honey also has very obvious bubbles when shaken), but as long as the temperature drops in autumn, there is no such phenomenon!

This is different from the fermentation of honey: common honey, such as 1-day honey, because of its large moisture, honey in addition to bubbles, there is a strong alcohol smell and pungent smell, sour rock socks, fermentation, has been inedible.
