The kinetics of hydrolysis ofNigella sativa (black cumin) seed oil catalyzed by native lipase in ground seed

Abstract

Kinetics of the lipolysis ofNigella sativa oil catalyzed by native lipase in crushed seed were studied between 20 and 90°C. Data fitted the pseudo first‐order rate equation at 20, 30 and 40°C; and the pseudo second‐order equation at 50, 60 and 70°C, but neither equation fit at 80 and 90°C. Lipolysis approximated first‐order with respect to water.
