Question

How much is boric acid powder need to mix in 50kg rice?

Answer 1

4 grams or 1 spoon boric acid for 1 kg rice.

So 200 grams or 10 spoons for 50 kg.

It has been seen that boric acid or H3BO3 powder is a good preservative for rice. It is a insecticide which kills all the bugs. Boric acid powder can be bought from a chemist's shop for domestic use. 1 spoon of boric acid can be mixed 5 kg of rice to get rid of the bugs. The grains of rice should be washed properly before cooking in order to avoid any harmful effects of the acid.

Answer 2

Boric acid or H₃BO₃ is usually sprinkled in rice as a preservative and to keep rice grains away from insects, worms etc.

Usually, 100 gms of boric acid is mixed with 20 or 25 kg of rice. So, for 50 kgs of rice, 200 gms of boric acid powder should be sufficient.

However, research says that there is no guarantee that adding boric acid will keep the insects and worms away from rice after adding the boric acid powder. Also, it is recommended that the rice is washed well before it is cooked to remove all the boric acid powder.
