Abstract: | Among various cooking quality parameters, differential length/breadth ratio has been found to be a reliable indicator of adulteration of Basmati rice, with Improved Sabarmati, Pusa-169, PR-106, Kali-much, Lakra and Parimal, which are the rice varieties used frequently for adulteration. A minimum value of length/breadth ratio of 3.92±0.09 to 4.09±0.09 was found to be indicative of pure Basmati. |
