The shelf life of sugar is 1-2 years.

Sugar has a shelf life. On the surface, it can be stored for 1 year. Therefore, expired sugar can be eaten if it looks like it has evaporated and has not deteriorated.

The food regulations must indicate the shelf life, so enterprises usually indicate the shelf life ranging from 1-2 years. But if it is stored for a long time, it will lead to excessive mites and microorganisms, so don't eat it indirectly.

Can white sugar still be eaten after three or four years?

Sugar can't be eaten after three years.

Under normal circumstances, the shelf life of white sugar is 18 months -24 months, so white sugar has been stored for three years and belongs to expired food. Expired white sugar is easy to breed a large number of bacteria, and eating it will affect your health, so you can't eat white sugar after three years.

White sugar is refined sugar made from molasses squeezed from sugarcane and sugar beet. White sugar is white, clean and high in sweetness. White sugar contains sugar, which is one of the main sources of nutrition for human body. The consumption of human body depends on the heat energy generated by sugar oxidation, and about 70% of the energy needed for human activities is provided by sugar.

How to identify white sugar with mites

The way to check whether there are mites in sugar is to put a little sugar on white paper and observe it more than 5 times with a magnifying glass. If there are pits in the sugar, it means there are mites.

How to judge the deterioration of white sugar

White sugar is an essential condiment in our life. Any dessert we usually eat is inseparable from white sugar. If you like sweets, you will definitely buy a lot of sugar to store at home, and you can take it out for easy use when you need it, so you don't have to go to great trouble to buy it. Then the temperature is higher in summer. If sugar is not stored under certain storage conditions, it will easily deteriorate, and it will easily expire if it is stored for too long. So how should we judge whether the sugar has expired? I believe everyone must be curious, so let's take a look at science and teach you how to judge whether sugar has expired.

Method 1:

First of all, we can judge from the packaging that the shelf life of four foods in the Regulations on the Administration of Food Labeling can be exempted, including vinegar, edible salt, solid sugar and drinks and wines with alcohol content ≥ 10%. But now the country's requirements for food safety are more and more strict, requiring manufacturers to indicate the shelf life on the packaging label of white sugar, so as to avoid the symptoms of increased dust mites, allergies and excessive heavy metal content in white sugar that has passed the shelf life. The shelf life will be shown on the label of sugar.

Method 2:

If it's not packaged sugar, you can tell if it's expired by the texture. Expired sugar will not only agglomerate, but also change color and turn yellow. This kind of yellow sugar may breed sweet fruit mites, and it prefers sweets, such as white sugar, brown sugar and candied fruit.

This is how to judge whether the sugar has expired. I believe everyone will learn it soon.
