Abstract

Banana (Musa sp.) is commercially one of the widely cultivated crops in the tropical and subtropical countries. Banana peels are classic example of such abundantly available natural material which is underutilized, despite the fact that it provides wide range of benefit. Besides, they can be used as a potential supplement in food ingredients for their nutritional value. Hence, this study was conducted to determine and compare the proximate composition and functional properties of Pisang Tanduk (PT) and Pisang Abu (PA) peels. The fresh samples were obtained from Banting and Petaling Jaya, Selangor, and they were cleaned, freeze-dried and ground into powder. Proximate composition was analysed using the AOAC methods and total dietary fibre (TDF) was determined using Prosky and Lee method (AACC Method 32-07.01). Four functional properties were analysed, i.e. bulk density, water absorption capacity (WAC), oil absorption capacity (OAC) and gelling property. Three samples of each banana peel sample Data were recorded in the duplicates of three (n=3) and are expressed in mean and standard deviation. From this study, PT peel contained 0.16% moisture, 12.00% ash, 14.23% protein, 5.40% fat, 32.69% TAC, 35.39% TDF, 26.33% IDF, 6.32% SDF and bulk density (0.81 glml), WAC (1.83) and OAC (2.42). PA peel powder contained 0.12% moisture, 15.00% ash, 11.23% protein, 6.53% fat, 13.54% TAC, 53.47% TDF, 37.67% IDF, 15.87% SDF and bulk density (0.55 g/ml), WAC (1.67) and OAC (3.41). The proximate composition was significantly (p<0.05) different between PT and PA, except for the ash content (p>0.05). Moisture, protein and carbohydrate were superior in PT, whereas PA had higher fat and TDF. Regarding the functional properties, PT had significantly (p<0.05) high bulk density and WAC than PA. In contrast, PA had significantly (p<0.05) high OAC and formed gel at a low concentration, compared to PT. Overall, this study necessitates that the banana peel has enormous commercial potential as a source of nutritional and functional compounds that can add a higher value to the essential agricultural waste products.
