摘要: 葵花籽是一种优质的油料资源,是世界第四大油料作物。葵花籽不但含油量高,葵花籽油以其高达90%的不饱和脂肪酸和富含维生素E、胡萝卜素等营养成分的特点,被称为"保健油",有延缓衰老、调节新陈代谢和降低胆固醇等功能。采用酶辅助压榨法制备葵花籽油,在提高出油率的同时保留油脂的天然风味。通过单因素实验法研究了酶的种类、酶添加量、pH值、液固比、温度和时间对压榨葵花籽油出油率的影响,以确定最佳的工艺条件。结果表明,最佳工艺条件为:选用纤维素酶,酶添加量为0.7%,pH为4.5,液固比为25%,酶解温度为55℃,酶解时间为2.5 h。在此最佳条件下,出油率是传统冷榨法的3.48倍,油脂提取率达85%。

Abstract: Sunflower seed is a kind of high quality oil resources and the fourth largest oil crop in the world. The sunflower seed oil contains 90% unsaturated fatty acids, vitamin E and carotene, which can delay aging, regulate metabolism and reduce cholesterol. Sunflower seeds oil is prepared by enzyme-assisted pressing method to enhance oil yield and retain the natural flavor of the oil. The effects of enzyme types, enzyme dose, pH, liquid-solid ratio, temperature and time on oil yield of sunflower seeds were studied by single factor experiment and finally the optimum technological conditions were determined. The test effect of cellulose was best and the results showed that the optimized conditions were cellulose dose of 0.7%, pH of 4.5, liquid-solid ratio of 25%, temperature of 55℃, and time of 2.5 h. Under the optimum condition, the oil yield of sunflower seed is 3.48 times higher than that by traditional cold pressing method with the oil extraction rate of 85%.

Key words: Enzyme, pressing, sunflower seeds oil
