Evaluation The Effects Of Ultrasonic Parameters On Simultaneously Extraction And Size Reduction Of Lycopene From Tomato Processing Waste
Published 2020 · Materials Science
Lycopene was simultaneously extracted from tomato processing waste and size reduced into nano-ranges from 36 to 150 nm, via ultrasonic assisted nanoprecipitation technique. The effects of main processing parameters namely, organic to aqueous phase ratio, ultrasonic amplitude and time were evaluated on mean particle size, polydispersity (PDI) and lycopene content of produced nanodispersions, using response surface method based on central composite design. All studied parameters affected the selected responses significantly (p-value < 0.05). The studied characteristics’ changes were significantly (p-value < 0.05) fitted to second order polynomial regression models of studied independent parameters by quite high coefficients of determination (R 2 > 0.9). The most desirable lycopene nanodispersions with mean particle size of 66.3 nm, PDI of 0.245 and lycopene content of 52 mg/g waste, were produced at organic to aqueous phase ratio of 0.5, and ultrasonication for 20 min at amplitude of 70%. The resulted insignificant differences between experimental and predicted data, certified the suitability of suggested response surface models.
