How to know if the brown rice is real and not polished?

Usually, if it takes longer to cook, it is a sign that it is unpolished. On the other hand, if it cooks within 5-10 minutes only (quick cooking brown rice), it is a sign that it is polished. 

We suggest that you purchase brown rice from a conscious, reliable brand. One such brand is Satopradhan Vision. Here's the link to order their brown rice : https://satopradhan.com/products/organic-indrayani-brown-rice
