Study on pepper oleoresin ultrasonic assisted extraction from pepper
Dry pepper as raw materials, ethanol as an organic extraction agent, in the ultrasound-assisted extraction paste Oleoresin. The optimum conditions were as follows: 50% of ultrasonic power, ultrasonic extraction time of 50 min, the concentration of 75% ethanol extration, solid-liquid ration ratio of 1∶35, extrion temperature 70 ℃.
