What is the main ingredient of baking powder?

There are many substances in baking powder, the main components are sodium bicarbonate and tartaric acid, usually the compound of carbonate and solid acid. At the same time, baking powder is also an acid salt generated by neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water.

Baking powder is a compound additive, which is mainly used in the production of flour products and puffed food. When carbonate comes into contact with water and acid, it breaks down into several substances. In this process, carbon dioxide is released, but no flavor substances are produced, so the taste of the product will not be affected.

Tartaric acid is a kind of carboxylic acid, which exists in many plants, such as grapes and tamarind, and is also one of the main organic acids in wine. As an antioxidant, it can make food sour, and its greatest use is as a beverage additive.

1, types of baking powder

(1) baking soda (sodium bicarbonate): Under the action of acidic substances contained in food, baking soda can be decomposed into sodium ions, water and carbon dioxide gas, which can play the role of fluffy food.

However, the reaction of baking soda releasing gas needs the existence of acidic substances and can be completed in a short time. The initiation of the reaction is difficult to control, and excessive dosage will produce bitter or astringent taste. For these reasons, baking soda is rarely used as a filler alone, but is usually used as one of the components of composite fillers.

(2) Alum (aluminum potassium sulfate or aluminum potassium sulfate, S.A.S): The commonly used alum is actually an acidic mixture, which releases gas when it reacts with the inherent or added ingredients of food, such as baking soda, and plays a fluffy role. Generally, it is also used as an acidic component of composite expansive agent. It is characterized by rapid reaction at high temperature. A common example is fried fritters.

2, the use of baking powder

(1) Cat litter deodorizes. Parents who keep cats at home can remove the feces from the cat litter, sprinkle a certain amount of baking powder and mix well, which can remove the odor in the cat litter, while baking soda itself is tasteless and will not affect cats.

(2) Sprinkle baking soda near the cat's toilet and mop the floor with water. On the one hand, it can remove the cat litter attached to the ground, on the other hand, it can partially kill the germs and parasite breeders on the ground, playing a role in disinfection and cleaning.

(3) Adding part of baking soda into pet drinking water and precipitating tap water for 24 hours can absorb part of chlorine and acidic substances in tap water and kill some propagules in the water. In addition, the water regulated by baking powder can be weakly alkaline, which is beneficial to digestion and absorption and active intestines.
