| Abstract: |
| 【Objective】 The research was to study the optimum conditions for extracting naringin from pummelo peels with ultrasound extraction technology.【Method】 The effects of ultrasonic temperature,time,power,solid-liquid ratio and ethanol concentration factors on the naringin extraction rate were investigated by single-factor experiments.Based on the above work,the orthogonal layout method was used in the optimization of technological parameters.【Result】 When extraction time was 1 hour,the optimum conditions of ultrasound extraction on naringin were as follows:ultrasonic temperature 50 ℃,solid-liquid ratio 1∶30,ethanol concentration 50% and ultrasonic power 25 W.【Conclusion】 The extraction rate of naringin was 5.437%. |
