Question

How much boric acid powder needs to mix in 50kg of rice?

Answer 1

• Boric acid, also known as ${\mathrm{H}}_3{\mathrm{BO}}_3$, is used in rice as a preservative and to protect rice grains from pests like worms and insects.
• Typically, 20 or 25 kg of rice are combined with 100 g of boric acid.
• Therefore, 200 gms of boric acid powder should be plenty for 50 kg of rice.
• Even if studies claim that there is no certainty that adding boric acid to rice can kill these insects, we should wash the rice three times or more before cooking it.
