Baking Soda Definition
Baking soda is a chemical substance that is a salt composed of sodium and bicarbonate ions, primarily used as a leavening agent in baking.
- The chemical name of the substance is sodium bicarbonate or sodium hydrogen carbonate with the chemical formula, NaHCO3.
- Baking soda is a solid white crystalline compound that exists as a fine powder. It is an odorless compound that is slightly salty in taste.
- Baking soda is a simple chemical compound that is composed of a single compound and doesn’t have other substances.
- It doesn’t have any acidifying or drying agents and is involved in the expansion of the batter resulting in the characteristic spongy texture in cakes and bread.
- The sodium bicarbonate undergoes thermal decomposition to release sodium carbonate, water, and carbon dioxide.
- Baking soda has weak disinfectant properties and is also used as an effective fungicide against some microorganisms.
Baking Powder Definition
Baking powder is a chemical substance composed of a mixture of carbonate or bicarbonate and a weak acid.
- The reaction between the acid and base present in the mixture is prevented by the addition of a buffer in the form of cornstarch.
- The cornstarch also works as a drying agent, whereas the cream of tartar works as an acidifying agent. Other compounds like monocalcium phosphate and sodium aluminum sulfate can also be used as the acidifying agent.
- Baking powder is also used in baking to increase the volume and lighten the texture of baked goods.
- Baking powder can also be used in the place of yeast, where the flavor of fermentation is undesirable.
- Baking powder also releases carbon dioxide at a faster rate through the acid-base reaction than through fermentation.
- Therefore, the production of baking powder has been revolutionary in minimizing the time and labor required for the production of baking goods.
10 Major Differences (Baking Soda vs Baking Powder)
|Characteristics||Baking Soda||Baking Powder|
|Definition||Baking soda is a chemical substance that is a salt composed of sodium and bicarbonate ions, primarily used as a leavening agent in baking.||Baking powder is a chemical substance composed of a mixture of carbonate or bicarbonate and a weak acid.|
|Composition||Baking soda is a pure substance composed of sodium bicarbonate.||Baking powder is a mixture of chemical substances like sodium bicarbonate, cream of tartar, and cornstarch.|
|Acidifying agent||Baking soda doesn’t have any acidifying agents.||Baking powder contains an acidifying agent, which can be cream of tartar or a mixture of monocalcium phosphate and sodium aluminum sulfate.|
|Drying agent||Baking soda doesn’t have any drying agent.||Baking powder contains cornstarch as a drying agent.|
|In baking||During baking, the product should be baked immediately after the addition of baking soda.||The product can be kept for some time before baking after the addition of baking powder.|
|Baking soda results in the spread of the product during baking.||Baking powder results in the puffing of the product during baking.|
|Baking Time||Baking soda requires a shorter baking time.||Baking powder requires a longer baking time.|
|Ingredients||Baking soda is used with acidic ingredients like buttermilk and lemon juice.||Baking powder is used with non-acidic ingredients like regular milk and flour.|
|Activated By||Baking soda is activated by heat which causes the thermal decomposition of the compound to release carbon dioxide.||Baking powder is usually activated by liquid, but double-acting baking powder might require heat.|
|Other uses||Baking soda can be used for cleaning or as a neutralizing salt.||Baking powder is strictly used for baking.|
