Because white sugar contains sulfur dioxide, ID cards are required to prevent buyers from using it illegally.
When oxidizing agents are added to sugar, violent reactions may occur and even explosions may occur. In a normal living environment, white sugar will not undergo any changes, but when the white sugar is in a molten state, adding an oxidizing agent to the white sugar will cause a violent chemical reaction. Such as potassium permanganate, sodium nitrate, potassium nitrate, potassium chlorate (white medicine), ammonium perchlorate, chromium trioxide, etc.
White sugar is mainly divided into two categories, namely white granulated sugar and soft white sugar. White sugar is more commonly consumed abroad, and soft white sugar is mainly consumed in countries or regions within the Chinese food culture circle. The standards and classification of white sugar vary from country to country. China divides white sugar into four levels based on the degree of refining, namely refined white sugar, superior white sugar, first-grade white sugar, and second-grade white sugar. Soft white sugar is divided into three levels, namely refined soft white sugar, superior soft white sugar, and first-grade soft white sugar.
White sugar is refined sugar made from molasses squeezed from sugar cane and beets. White sugar is white in color, clean and has high sweetness. White sugar is easily contaminated with pathogenic microorganisms during the production, packaging, transportation, and storage processes. Especially white sugar that turns yellow after being stored for more than a year is often contaminated by mites. According to experiments, 15,000 mites were detected in 500 grams of white sugar. If people eat white sugar contaminated with mites, the mites will enter the digestive tract and parasitize, causing abdominal pain, diarrhea and other symptoms, and some may even cause allergic reactions. If this kind of contaminated raw sugar is directly added to the food of infants or the elderly, mites may enter the lungs due to choking and coughing, causing asthma or hemoptysis, and may easily lead to bronchitis or pneumonia.
