- Abstract
Mahua ( Madhuca longfolia) extract and black grapes ( Vitis vinifera) must samples 100:0 (grape:mahua), 95:5 (grape:mahua) and 90:10 (grape:mahua) were analyzed for quality characteristics. Samples were kept for fermentation and monitored for quality analysis for 15 days. 90:10 (grape:mahua) sample was found to be best on the basis of ranking test and subjected to clarification using bentonite and gelatine. Sample treated with a combination of 0.02 g/100 g bentonite and 0.04 g/100 g gelatin showed better results for anthocyanin (52.2 mg/100 g) and tannin (0.038%w/v). After ageing of 3 months TSS was found highest (2.7ºBx) in the non-clarified sample and lowest (2.1ºBx) in sample treated with 0.06 g/100 g bentonite and 0.03 g/100 g gelatine. pH was highest (3.29) in sample treated with 0.06 g/100 g bentonite and 0.03 g/100 g gelatine and lowest (3.16) in sample with 0.04 g/100 g bentonite and 0.03 g/100 g gelatine. Anthocyanin content was highest (56.1 mg/100 g) in control sample and lowest (29.22 mg/100 g) in sample treated with 0.04 g/100 g bentonite and 0.02 g/100 g gelatin. Tannin content was found to be highest (0.079%w/v) in control sample and lowest (0.03%w/v) in sample treated with 0.02 g/100 g bentonite and 0.04 g/100 g gelatine.
