The sourness in curd is due to which acid?

Answer and explanation

Correct answer: Lactic acid

The governing concept is the formation of acids during fermentation. Bacteria convert some lactose in milk into lactic acid as curd forms, and this lactic acid produces the characteristic sour taste. Citric acid is linked with citrus fruits, formic acid with sources such as ant stings, and sulphuric acid is a strong mineral acid rather than the normal acid in curd. Therefore, option A is correct.
