1. White sugar How long can it be stored
1. The shelf life of white sugar is generally about 18-24 months. The storage time of white sugar is affected by many factors such as climate conditions, processing quality, and storage conditions. The shelf life of white sugar produced by different manufacturers will vary. Hot weather and improper storage conditions will also shorten the shelf life of white sugar.
2. In GB13104-2014, white sugar is defined as sugar cane or sugar beet as raw material, which has been extracted from sugar juice, purified, boiled, crystallized and separated. Cane sugar crystals made by technological processing. Soft white sugar is in powder form and is suitable for cooking. Its sweetness is similar to that of white granulated sugar. There are two types of soft white sugar: refined soft white sugar and native soft white sugar. The former is white in color, has fine and soft grains, and is of better quality; the latter is slightly yellower and darker in color, and of poorer quality.
2. The difference between glucose and white sugar
1. Glucose belongs to Monosaccharides are organic compounds that are easily soluble in water and slightly soluble in ethanol;
2. White sugar is refined white sugar squeezed from sugar cane and beets. It is white in color. , high sweetness and a disaccharide substance.
3. The heat released by the redox reaction of glucose is the key source of heat needed by the human body, and the human body will absorb glucose faster;
4. White sugar is white in color, with grains like sand. It melts in the mouth and is poorly absorbed by the human body.Slightly slower than glucose.
3. The difference between white sugar and granulated sugar
When making dishes , usually put in white sugar, which melts into the soup better and can penetrate into the food better.
Granulated sugar is generally used on some pastries. For example, when making bread or cakes that need a layer of sugar flowers, some white granulated sugar will be sprinkled on them because it is not very sticky. Melts easily.
White sugar is made into white sugar with very small particles and added with invert syrup.
White sugar is made from sugar cane or beets by extracting juice and then going through processes such as crystallization, into granular form.
4. What kind of sugar is white sugar?
White sugar is Of sucrose. When sugar is first extracted from raw materials, it is always colored, mostly reddish brown, either dark or light, which is the color of our common brown sugar. After the brown sugar is processed and filtered, and the pigments are removed, the white sugar we see now is formed. This is what our teacher mentioned when talking about the origin of sugar cane in class.
5. What are the main components of white sugar
1. White sugar It is refined sugar made from molasses squeezed from sugar cane and sugar beets. White sugar is white in color, clean and has high sweetness. White sugar contains sugar, which is one of the main sources of nutrition for the human body. The human body\’s consumption is maintained by the heat energy generated after the oxidation of sugar. About 70% of the energy required for human activities is supplied by sugar.

About 70% of the energy required for human activities is supplied by sugar.
3. White sugar is mainly divided into two categories, namely white sugar and soft white sugar. White sugar is a crystal of sucrose. Crystallized sucrose melts into a thick and transparent liquid when heated to 160°C, and recrystallizes when cooled. When the heating time is extended, sucrose is decomposed into glucose and fructose. At higher temperatures of 190-220°C, sucrose dehydrates and condenses intoFor caramel.
6. How does white sugar come from
White sugar comes from sugar cane Or extracted from beets. The production process is as follows:
1. Sugarcane pretreatment. Pretreatment refers to cleaning the sugar cane and then cutting and crushing it.
2. Press. After pretreatment, the sugar cane is sent to the press for crushing, and the sugar cane is divided into juice and bagasse.
3. Clean the cane juice. Freshly pressed, it is just turbid. In addition to the main component sucrose, there are many impurities. Cleaning cane juice is divided into filtering insoluble impurities (cane chips, sediment, etc.) and precipitating soluble impurities (various organic salts, colloidal substances, inorganic salts, etc.). When precipitating soluble impurities, chemicals need to be added to precipitate the impurities, and then the precipitates are separated to obtain clear, transparent juice with low color.
4. Evaporate cane juice. That is, the cane juice is evaporated and concentrated. Although this step is not a critical step, the steam can be reused. For example, it can be used for next heating, drawn out for use by other equipment, etc.
5. Cane juice crystallization. The sugarcane juice becomes syrup after evaporation and concentration, and then undergoes a series of processing, namely concentration, crystallization, concentration again, recrystallization, crystallization assistance, centrifugation, separation, and drying to obtain the finished sugar.
