Will white sugar expire, how to tell if white sugar expires

White sugar is expired. If it is ordinary white sugar and sucrose.

For the extract, according to the relevant national regulations, it is divided into 18-24 months according to different factors such as outer packaging. In addition, the storage of white sugar should be kept away from light, and the temperature should be controlled below 20°, so that the sugar can be dried for a long time and its properties will not change.

White sugar is a good microbial culture agent. As long as it is within the expiration date.

The white sugar stored in the inner seal is safe and can be eaten with confidence. However, canned sugar and bulk sugar that are not tightly sealed are easy to breed mites after being disturbed or polluted by humid air.

Over time, mites and other flora will multiply in the sugar.

White sugar will expire. White sugar is very susceptible to contamination by pathogenic microorganisms in the process of packaging and fortune, if the color of white sugar turns yellow, it has deteriorated, and if it is eaten by mistake, it may cause physical discomfort. White sugar contains calcium, magnesium, iron, carbohydrates, manganese, zinc, copper, potassium and other nutrients, which can supplement certain nutrients for the human body.

White sugar: White sugar is refined sugar made from molasses extracted from sugar cane and sugar beets. The sugar is white, clean and has a high sweetness.

White sugar contains sugar, sugar is one of the main nutrients of the human body, the consumption of the human body to be maintained by the heat energy produced after the oxidation of sugar, about 70% of the energy required for human activities is supplied by sugar. Sulfide sugar sulfurous acid method clarification technology is a typical cane juice and syrup cleaning and decolorization method in the white sugar production industry, because the method has less equipment, the process flow is relatively simple, the management is convenient, etc., therefore, this clarification technology has been widely used in China's sugar industry. However, compared with the carbonic acid clarification technology, because the sulfurous acid method clarification process relies on calcium phosphate and calcium sulfite to adsorb impurities in the cane juice, and the sulfur bleaching effect of the syrup is based on the principle of reduction reaction, the quality of the white sugar produced by the sulfurous acid method sugar factory is often poor, and there is a phenomenon of yellowing after a long time.

Sugar is an indispensable condiment in our lives, any sweet food we usually eat is inseparable from sugar, if you like to eat sweets, friends will definitely buy a large amount of sugar at home for storage, and when you need to use it, you can easily take it out and use, no need to go to great lengths to buy. Then the temperature is relatively high in summer, and if the sugar is not stored under certain storage conditions, it is easy to deteriorate, and it is easy to expire if it is stored for too long. So how should we tell if white sugar is expired?

I believe everyone must be very curious, so let's popularize science for you and teach you how to judge whether sugar is expired.

Method 1: First of all, we can judge by looking at the packaging, the previous "Food Labeling Management Regulations" four types of food can be exempted from the standard shelf life, including vinegar, edible salt, solid sugar and ethanol content of 10% beverage wine, but now the country has more and more strict food safety requirements, requiring manufacturers to indicate the shelf life on the white sugar packaging label, to avoid eating white sugar after the shelf life, resulting in the body has increased dust mites, allergies, heavy metal content and other symptoms. The expiration date is shown on the label of the sugar.

Method 2: If it is not packaged white sugar, we can identify whether it is expired by looking at the texture, the expired white sugar will change color in addition to agglomeration, and the color will turn yellow, this yellow white sugar may breed sweet fruit mites, this small mite prefers sweet foods, such as various white sugar, brown sugar and candied fruit and other sweets.

The above is how to judge whether the sugar is expired, I believe you will be able to learn it soon.

It will expire, and it is best not to eat the sugar if it is left for too long, it will deteriorate after a long time, and there may be mite breeding.

The shelf life of white sugar is generally one year, and it has been left for a year or more, so it is best not to eat it. Because white sugar will turn yellow after a long time, and the nutrients in it will slowly decrease.

Eating a large amount of this white sugar will also cause some sweet fruit mites with strong viability to parasitize in the intestinal lumen or intestinal wall to cause intestinal mite disease, and the clinical manifestations vary from person to person and the degree of infection, and most patients show symptoms such as abdominal pain, diarrhea, and vomiting.

In addition, if mites enter the human body through the respiratory tract, it is easy to cause allergies.

White sugarIt cannot be used again after expiration.

This is because sugar or other foods have a shelf life set at the time of production.

However, the bacteria derivation of food within the shelf life will be slower and the amount will be very small, so that most of the nutrients in it can be retained.

Post-expiration and reaction:

White sugar is a more common food in life, its shelf life is generally about 18 24 months, beyond the shelf life of white sugar will breed a large number of bacteria and mites.

If people come into contact with or eat it, it will not only cause harm to people, but also have a certain impact on physical health.

When storing the white sugar within the shelf life, it is also necessary to pay attention to the preservation method, if the storage method is improper, it will lead to a shortening of its shelf life. White sugar is absorbent and not resistant to high temperatures, so it should be noted that it should be stored in a relatively dry environment to avoid moisture.

White sugar will expire. If the sugar is stored for too long, the sugar will breed mites.

White sugar is a good microbial culture agent. As long as the white sugar is sealed and stored within the expiration date, it is safe and can be eaten with confidence. However, canned sugar and bulk sugar that are not tightly sealed are easy to breed mites after being disturbed or polluted by humid air, and over time, mites and other bacteria will multiply in the sugar.

After drinking white sugar water and vegetable juice containing mites, people are prone to stomach pain and diarrhea. This is more common in the South. In the north, due to the dry air, white sugar is not easy to breed mites.

However, white sugar that has been left for a long time and turns yellow will still breed mites, and such white sugar is likely to cause abdominal pain and other physical discomfort after eating.

White sugar is a common food additive, and unlike many other foods, sugar can almost never expire. This is because the sugar itself does not mold, does not rot, and does not ferment.

So, why doesn't white sugar expire?

First of all, white sugar has a very low moisture content.

Mold and fine wheels make bacteria need water to survive and multiply, while the water content in white sugar is very low, and it is basically impossible to maintain the survival of microorganisms.

White sugar is expired. If it is an ordinary food reputation, it is divided into 18-24 months according to different factors such as outer packaging according to the relevant national regulations. In addition, the storage of white sugar should pay attention to avoid light, and the temperature should be controlled below 20° when celebrating and laughing, so that the sugar can be dried for a long time and its properties will not change.

There are three main reasons why white sugar doesn't expire:

1.White sugar is a kind of dry food, which has undergone heating and evaporating water, crystallization, filtration and drying processes in the production process, and the water content is very low, and it is difficult for microorganisms to survive and reproduce in such an environment.

2.The sugar in white sugar is very stable, its chemical structure is relatively stable, and there is no obvious chemical change and decomposition reaction under normal circumstances.

3.The correct way to store white sugar is to keep it in a dry, cool, and ventilated environment to avoid exposure to unfavorable factors such as moisture, odor, strong light, and high temperature.

If it is not stored properly, even if the sugar does not expire, the pie may deteriorate.
