Powder drink from banana peel pectin and rice bran rich in dietary fiber

Abstract

Banana peel and rice bran are the food waste that can be potential sources of dietary fiber. This research aims to discover the best formula for functional beverage powder which contains high dietary fiber and which is favored by the panelist. The formulas are devised based on the ratio of kepok banana peel pectin and rice bran. The ratio for F1 is (1.5g: 2.5g), F2 (2g: 2g) and F3 (2.5g: 1.5g). After 120-minute extraction, the pectin of kepok banana peel has 5% of yield, 7.96% of water content, 8.52% of ash content, 705.08 of equivalent weight, 4.85% of methoxy level and 54.218% of esterification degree. A hedonic test indicates that the taste of the drink resulting from all three formulas is not significantly different. The color of the drink powder produced using formula 1 and formula 2 is more favored compared with that produced using formula 3 but the aroma of the drink powder produced using formula 3 is the most preferred. The soluble fiber content of pectin is 8.41% meanwhile the soluble and insoluble fiber content of rice bran is 5.28% and 23.90% respectively; the content for F1 is 7.75%,17.76%; F2 6.79%, 19.34%; F3 5.40%,21.65%.
