Pengaruh Jenis Pelarut dan Waktu Ekstraksi Pada Metode Microwave Assisted Extraction Terhadap Karakteristik Pewarna Ekstrak Kulit Buah Naga Kuning (Selenicereus megalanthus)


 This study aimed to determine the effect of type solvent and extraction time using method Microwave Assisted Extraction (MAE) on pigment characteristics yellow pitaya peel extract find right produce with best colorant characteristics. The research design used was a randomized block 2 factors. First factor (ethanol, ethyl acetate, n-hexane). Second in MAE (6,8, 10 minutes). treatment repeated twice get 18 experimental units. data were analyzed statistically variance test if had significant observed variables, it continued Duncan's Multiple Range Test. results showed that interaction very (P<0.01) yield, total carotenoids, suspended solids (TSS), L *, b * values, phenolic, antioxidant activity, IC50. found n-hexane minutes yield 10.00%, carotenoids 33.40 mg/g, dissolved 19.54%, brightness (L*) 41.25, redness (a*) 19.86, yellowness (b*) 53.87, phenolic 3.09 mg GAE/g, activity 65.97%, IC50 777.773 ppm.
