摘  要:
为了确定复合酶法提取苹果籽油的工艺条件,以秦冠苹果籽为原料,通过单因素试验和正交试验,对其工艺条件进行了优化。结果表明,复合酶法提取苹果籽油的优化工艺条件为:苹果籽破碎度≤0.6 mm,料液比1∶8,复合酶添加量0.8%(纤维素酶与酸性蛋白酶质量比1∶1),酶处理时间8 h,pH值4.6,常压蒸汽处理20 min,在该提取工艺条件下苹果籽出油率高达21.44%。与溶剂浸出法相比,复合酶法具有出油率高和油品质好等特点。

摘  要:
The paper focused on the study of extracting edible oil from apple seeds by using complex enzymatic method,with the Qinguan apple seeds as the subject.Based on a single and orthogonal experiment,the optimum conditions were found as follows:the fragmentation degree ≤0.6 mm;the solid/liquid ratio,1∶8;the amount of complex enzymes(fibrinase:acid protease=1∶1,m/m),0.8%;the reaction time,8 h;pH value 4.6;detoxification time,20 min.Under the above conditions the extraction rate was 21.44%.The result shows the complex enzymatic method has many advantages in improving yield and quality compared with the traditional solvent extraction methods,and predictably it will be widely employed in oil-extracting industry.
