Question

Name the constituents of baking powder and write the function of each constituent of baking powder in cake manufacturing.

Answer 1

Baking powder is a mixture powder of baking soda and a mild edible acid such as tartaric acid.
When baking powder mixes with water present in dough for baking then sodium hydrogen carbonate reacts with tartaric acid to evolve CO2 gas.
The CO2 gas produced gets trapped in wet dough and bubbles out slowly making the dough to rise and become soft and spongy.
NaHCO3  + H + (ions of edible acids) -> Na+ + CO2 + H2O

Answer 2

Baking powder is a mixture of baking soda and a mild edible acid like tartaric acid.

∴ Baking powder =Baking soda + mild edible acid

Baking powder is used in preparation of cakes and breads to make it soft and fluffy.

Chemical reaction :NaHCO3 + H⁺ ions of edible acid ----> Salt of edible acid +CO2 +H2O

due to neutralization reaction of acid and NaHCO3 a salt is produced which gives sweet smell to cake.CO2 produced will make the cake soft and fluffy.
