- Abstract
The sesame was used as raw material to extract sesame oil by ultrasonic-assisted aqueous enzymatic method. The effects of ultrasonic treatment conditions (treatment time and treatment temperature) and enzymatic hydrolysis conditions ( material-to-liquid ratio, acid protease mass fraction, enzymatic hydrolysis pH, temperature and time) on sesame oil yield were discussed. The results showed that the optimal extraction conditions for sesame oil were as follows: ultrasonic treatment time was 15 min, ultrasonic treatment temperature was 50 °C ; material-to-liquid ratio was 1 : 10, acid protease mass fraction was 0. 16%, enzymatic hydrolysis pH was 3.0, hydrolysis temperature was 45 °C, hydrolysis time was 5 h. The seasame oil extraction verification test was carried out under these conditions, the yield of sesame oil could reach 43. 28%, and the obtained seasame oil had good oil quality and less pollution, which indicated that it was feasible to extract sesame oil by ultrasonic-assisted aqueous enzymatic extraction and superior to many conventional methods.
