The chemical name of saccharin is phthalimide, and the commercially available saccharin is actually the soluble sodium salt of phthalimide, referred to as saccharin sodium. The sweetness of saccharin sodium is about 450 to 550 times that of sucrose, so its1100000 aqueous solution has a sweet feeling, and it will be bitter when the concentration is high. Saccharin sodium is a synthetic product of organic chemical industry, and it is a food additive rather than a food. Except for sweetness, it has no nutritional value to human body. On the contrary, eating too much saccharin will affect the normal secretion of gastrointestinal digestive enzymes, reduce the absorption capacity of small intestine and reduce appetite. However, in heated eggs, amino acids and phthalimide will react chemically to produce a compound called glycosyl lysine, which destroys the amino acid composition in eggs. The produced compounds are toxic, but excessive dosage can lead to death. Coptidis Rhizoma 15g must be decocted in water for detoxification.
