Abstract

The extraction conditions of polyphenols from guava by ultrasound were studied in this paper.Ultrasonic power,ethanol concertration,solid to liquid ratio,ultrasonic time conditions were tested in the single factor experiments,through response surface methodology,the regression equation of polyphenols extraction rate was obtained.The optimum technological condition are determined as: ultrasonic power is 350 W,ethanol concertration is 40%,solid to liquid ratio is 1∶30(m∶V) and the yield is 4.65 mg/g.
