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.

Leavening agent Chemical leavening agents can be divided into two types: one is alkaline leavening agent, such as sodium bicarbonate (baking soda), ammonium bicarbonate (stinky powder); the other is compound leavening agent, such as potassium alum and ammonium alum. Alkaline leavening agent slowly decomposes in the dough at a certain temperature, thereby releasing carbon dioxide and causing the dough to expand; compound leavening agent is a mixture of alkali agent, acid agent and filler. In the heated dough, the acid will It reacts with alkali to release carbon dioxide. The oldest fried dough sticks in my country are fried dough sticks with the chemical leavening agent alum added to flour. Alum contains aluminum, which is extremely harmful to the human body.
