Baking powder is more commonly used to make cakes or bread "rise". Filler in baking powder is

  • A
    $\mathrm{NaHCO}_3$
  • B
    $\mathrm{Ca}\left(\mathrm{H}_2 \mathrm{PO}_4\right)_2$
  • Correct answer
    C
    starch
  • D
    $\mathrm{NaAl}\left(\mathrm{SO}_4\right)_2$

Solution

An improved combination of baking powder contains about $40 \%$ starch, $30 \% \mathrm{NaHCO}_3, 20 \%$ $\mathrm{NaAl}\left(\mathrm{SO}_4\right)_2$ and $10 \% \mathrm{Ca}\left(\mathrm{H}_2 \mathrm{PO}_4\right)_2$. Here starch acts as filler.

Hence, the correct answer is option: 'C'.
