Food grade baking soda
Sodium bicarbonate (sodium bicarbonate), commonly known as baking soda, is a compound of the molecular formula NaHCO3. Chemical formula: NaHCO3, Einece number: 205-633-8
The physical properties of food-grade baking soda:
White crystalline powder, non-toxic, salty, soluble in water and aqueous solution, insoluble in ethanol. It is alkaline, dissolves in the air, changes in high temperature, and easily releases carbon dioxide. Its density is 2.16 ~ 2.22 g/cm3.
Baking soda is an alkali, and food-grade baking soda is widely used in various foods. For example, it is used to make soda bread and gingerbread, fruit cake, chocolate cake and carrot cake and other rich cakes. It needs an acid (and moisture) to activate it, so it is often mixed with tartar, yogurt, buttermilk or milk. The food additive baking soda is also widely used in daily life.
Baking soda releases carbon dioxide and expands in the mixture. Once the mixture is cooked, the carbon dioxide is replaced by air, leaving only a thin piece of cake or bread. As with all starters, use the amount specified in the recipe. Adding extra baking soda can result in a pointed or crumbled cake with a strong flavor and green hue.
