Study on the storage stability,flavor and nutrient composition of peanut oil by different pressing techniques
The storage stability,flavor and nutrient composition of peanut oil under different pressing process(cold-pressed,microwave pretreatment pressed and hot-pressed)were stud-ied in this paper.The results showed that there was no significant difference between microwave pretreatment pressed peanut oil and hot-pressed peanut oil in antioxidant capacity,storage sta-bility and flavor,and both were better than cold-pressed peanut oil.In terms of nutrient compo-sition,the total amount of VE and sterol in microwave pretreatment pressed peanut oil and cold-pressed peanut oil were significantly higher than those in hot-pressed peanut oil.
