压榨法制备接骨木籽油工艺优化及其活性成分分析Optimization of Sambucus williamsii seed oil preparation process by pressing method and analysis of its active components

为了促进接骨木籽的利用，采用压榨法制取接骨木籽油。以提油率为考察指标，通过单因素试验和正交试验对接骨木籽油的制备工艺进行了优化，同时对接骨木籽油的活性成分进行了分析。结果表明：压榨法制备接骨木籽油的最佳工艺条件为入榨水分含量7.0%、压榨机转速60 r/min、压榨温度90 ℃，在此条件下接骨木籽提油率为82.1%；接骨木籽油不饱和脂肪酸含量高达82.08%，维生素E、多酚、总黄酮的含量分别为23.8、32.7、38.3 mg/kg。接骨木籽油可作为一种优质植物油进行开发。 In order to promote the utilization of Sambucus williamsii seeds, Sambucus williamsii seed oil was prepared by pressing method. Taking the oil extraction rate as the investigation index, the preparation process of Sambucus williamsii seed oil was optimized by single factor experiment and orthogonal experiment, and the active components in Sambucus williamsii seed oil were analyzed. The results showed that the optimal conditions for preparing Sambucus williamsii seed oil by pressing method were obtained as follows: moisture content of the feed pressed 7.0%, speed of the press 60 r/min, pressing temperature 90 ℃. Under the optimal conditions, the oil extraction rate of Sambucus williamsii seed was 82.1%. The contents of unsaturated fatty acids in Sambucus williamsii seed oil was as high as 82.08%, and the contents of vitamin E, polyphenols, and total flavonoids were 23.8, 32.7, 38.3 mg/kg, respectively. Sambucus williamsii seed oil can be developed as a high-quality vegetable oil.
