The results showed that the POV of hemp seed oil was affected remarkably by temperature and time, and the effect of temperature was greater than that of time. The TBHQ had good antioxidation ability to hemp seed oil. TBHQ or BHA with isoascorbic acid or critic acid exhibited great antioxidation ability, the synergistic effect on the oil of critic acid was better than that of isoascorbic acid. When 0.02% TBHQ with 0.005% BHA and 0.01% critic acid or with 0.005%BHA and 0.01% isoascorbic acid was used in the oil, the shelf life of the oil could be prolonged from 4 months to 11~13 months at 20℃.
