| Abstract: | Response surface methodology（RSM） was applied to optimize the extraction conditions of tea seed oil . Based on single factor experiment, the amount of complex enzymes, enzyme hydrolysis pH, enzyme hydrolysis temperature and reaction time were chosen as influencing factors and the tea seed oil yield was selected as response value. The mathematical model was established by Box-behnken central composite design. The optimum extraction conditions were as follows： high-pressure steaming 20min, treating by ultrasonic wave 20rain, treating temperature 60℃, the ratio of material to liquid 1 ： 5, amount of complex enzymes 1.75%, enzyme hydrolysis pH 4.6, enzyme hydrolysis temperature 44℃ and reaction time 6.9 h. The tea seed oil yield was 29.88%. |
