Black rice mixed in white In the long grain white rice (parboiled) there these occasional grains of darker brown to black grains. Any idea what these are?
These are grains of rice that have not been polished. Rice comes in many colors. The outer hull needs removed like wheat. Then to mids or inner skin polished off. The mids is were the oil is. If not removed rice will go rancid in 3 to 4 months. They will not harm you.
