A Study for Extraction Kinetics of Β-Carotene from Oven Dried Carrot by Solvent Extraction
نویسندگان
چکیده
The main aim of this work was to study the kinetics of the extraction of β-carotene by solvent (ethanol) extraction from carrots dried at 50oC in an oven. The moisture content after drying was 11±1.5% (dry weight basis). Extraction time was 5 hours and extraction process was carried out at 30oC. The ratio of Carrot (gm): ethanol (ml) of 1:60 was maintained throughout the extraction process. The experimental data of extracted βCarotene yield during solvent extraction were modeled with seven different mathematical models, including Power law, Peleg, Weinbull’s equation, Pseudo 2 nd order, Intraparticle diffusion, Logarithmic, Weinbull’s distribution and one RSM model developed in this study. Pseudo 2 nd order model was best fitted model (R 2 0.99, χ 2 0.0091, RMSE0.1566, MAE0.0115) to describe extraction kinetics of β-carotene from carrot. The extraction time has significant effect on extraction process at p<0.05 level.
