Phthaloyl sulfoximide, commonly known as saccharin. The sweetness of dilute aqueous solution is about 300-500 times that of sucrose.
Aspartame (also known as sweeteners) was "accidentally" discovered in 1965, it is synthesized by L-phenylalanine and aspartic acid white powder, its sweetness feel good, taste close to sucrose, sweetness is about 150-200 times that of sucrose. It is about 150-200 times sweeter than sucrose. The sweetness of aspartame is more natural than that of saccharin, so it is popular among food production and processing enterprises. And because it is sweet, used in small amounts, and provides sweetness without too many calories, it is widely used
in beverages labeled as low-calorie, and is recommended for overweight and diabetic patients.
The main degradation products of aspartame during metabolism are phenylalanine and aspartic acid, which are harmless to normal people. However, for patients with phenylketonuria (PKU), due to its metabolic defects, too much phenylalanine in the body can affect the patient's development, so patients with this disease should be prohibited from adding aspartame to the food. Moreover, food products with aspartame must have a warning printed on the label or in the instruction manual stating that they are not suitable for people with phenylketonuria.
Phthaloyl sulfoximide, commonly known as saccharin. White crystalline powder. Melting point 228.8 ~ 229.7 ℃, density 0.828 g / cm3, slightly soluble in water, ether and chloroform, soluble in ethanol, ethyl acetate, benzene and acetone. Its sodium salt is called saccharin sodium or soluble saccharin, easily soluble in water, the sweetness of dilute aqueous solution is about 300 to 500 times that of sucrose. A small amount is non-toxic, but has no nutritional value. 1% aqueous solution is neutral.
