Abstract

The purpose of this study was to prove that a solution of ascorbic acid or citric acid was more effective than a mixture of ascorbic acid and citric acid in delaying browning on kepok bananas (Musa acuminata Colla.) Rather than using ascorbic acid or citric acid only. This research has been carried out at the Botanical Laboratory, Biology Department, Faculty of Mathematics and Natural Sciences, Lampung University, in November - December 2018. This research was conducted in a 3x3 factorial experiment. Factor A is Ascorbic Acid with a level of 3 concentrations: 0% v / v, 0.025% v / v, 0.050% v / v. Factor B is citric acid with a level of 3 concentrations: 0% v / v, 0.025% v / v, 0.050% v / v. Each treatment combination is repeated 3 times so that the experimental unit is 27. In this study using 2 parameters namely qualitative parameters and quantitative. The quantitative parameters in this study are browning index, total dissolved carbohydrate content. Qualitative parameters are reducing sugar level and dehydrogenase enzyme activity.Levene test, variance analysis, and BNJ test were carried out at 5% level. Ascorbic acid and citric acid can reduce the index of kepok banana browning. Ascorbic acid decreased the browning index by 21% and citric acid decreased the browning index by 39%. The interaction between ascorbic acid and citric acid in reducing the index browning of kepok bananas is not real Ascorbic acid decreases the total dissolved carbohydrate content by 59.93% b / v (0.025) and 66% b / v (0.050), respectively. Based on the results of the study it was concluded that a solution of ascorbic acid or citric acid was more effective in delaying browning of kepok bananas from a combination of ascorbic acid and citric acid.
