Ginger was dried using a cross flow dryer at 55 ± 2 <sup>0</sup>C for eight hours. Ginger powder was extracted at three different watts (400 W, 500 W, and 600 W), temperatures (50 <sup>0</sup>C, 60 <sup>0</sup>C, 70 <sup>0</sup>C) and time (10, 20, 30 min) for optimum yield.&nbsp; 6-gingerol content was found to be 21.15 ± 0.13 and 18.81 ± 0.15 mg/g in fresh ginger and dried ginger, respectively.&nbsp; Optimized condition obtained by RSM for 6-gingerol was 400 W, 70 <sup>0</sup>C at 10 min extraction time.&nbsp; The results of MAE are expressed by 2-D contour plot and response surface curve by keeping one variable constant which showed highest yield at 600 W, 70 <sup>0</sup>C for 30 min extraction time.&nbsp; Microwave assisted extracts exhibited higher antioxidant activity in comparison with conventional extracts.</p> Vedashree M, Madeneni Madhava Naidu ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://cirworld.com/index.php/jac/article/view/7357 Wed, 30 May 2018 04:49:06 +0000
