Inversion syrup is a light yellow transparent liquid with the characteristics of low viscosity, high solubility and water absorption, and good sweetness. The sweetness is 1.3 times that of sugar. When sucrose is catalyzed by a catalyst, it decomposes with water and is reduced to glucose and fructose. One molecule of sucrose is hydrolyzed into one molecule of glucose and one molecule of fructose, and the original optical rotation of sucrose also changes from left-handed to right-handed. The converted mixture is invert sugar. After the reaction, alkali solution is added to neutralize the acidity. You get invert syrup.
