以大黄鱼内脏为原料,采用钾法提取粗鱼油,研究了水解pH值、水解温度、水解时间、KCl用量和盐析时间5个因素对大黄鱼内脏鱼油提取率的影响.通过单因素试验和正交试验得到钾法提取鱼油的最佳工艺条件为料液比1:1、水解pH8.0、水解温度60℃、水解时间30min、KCl用量6％和盐析时间15 min,该条件下鱼油提取率为83.03％.%In this paper, we extracted crude fish oil from the viscera of Pseudosciaena crocea by potassium method , and studied the effects of pH value , extraction temperature , extraction time, KC1 amount and salting out time on the extraction rate. Based on single factor and orthogonal experiments, we determined the optimum fish oil extraction conditions as follows; material-to-liquid ration 1: 1 ,pH value 8. 0,extraction temperature 60℃ , extraction time 30 min, KC1 amount 6% and salting out time 15 minutes. Under the optimum conditions, the fish oil extraction rate reached 83.03%.
