Abstract:

The optimal processing conditions of ultrasound-assisted extraction for ostrich oil were explored by single-factor experiments and rotation composite design to investigate the effects of extraction temperature, extraction time, ultrasonic power, and material-liquid ratio on extraction rate of ostrich oil. Results indicated that the optimal processing parameters of ultrasoundassisted extraction for ostrich oil were extraction temperature of 65 ℃, extraction time of 25 min, ultrasound power of 140 W and material-liquid ratio of 1:8. Under the optimal extraction conditions, the extraction rate of ostrich oil was up to 93.9%.

Key words: ostrich oil, ultrasound, extraction
