| dc.description.abstract | There were many studies about potential of red betel leaves in case of diabetes prevention. One study showed the potential of red betel as antihyperglicemic either alone or in a mixture with other materials. This study aims to improve the taste of the functional beverage, analyze volatile components, and determine the shelf life of the functional beverage. This study begins with the preparation of raw materials, followed by selected functional beverage formulation, bottling, shelf life estimation, and the transformation of a shelf life into expiration time. At the beginning of the study, improvement of beverage is done by adding lime juice in 5 levels of comparison, either in the form of extracts of whole fruit or fruit juice broth, sensory testing to get 3 formula was selected, and determination of the characteristics of functional drinks. The results showed that the addition of lime juice at volume ratio of red betel, ginger, cinnamon, and lime is 5:4:3:4 with panelists approached the level of preference “rather like”. Level of preference is approximately equal to the level of preference drinks before coupled with lemon, but increased inhibition of the enzyme α-glucosidase to 79.51%, has the antioxidant capacity of 442.09 ppm AAE and 411.75 ppm for total phenols. The bottling process is done by pasteurization at a temperature of 63°C for 30 minutes and drink packaged in dark glass bottle. The beverages that have been bottled is then stored at three different temperatures (5°C, 30°C, and 50°C). Furthermore, the stability observed during 6 weeks of storage products includes pH, TAT, total phenol, TPC, and color using the Accelerated Storage Studies (ASS). Determination of the reaction rate of food deterioration by temperature differences do with the Arrhenius method. Now we know the shelf life of each of the above parameters, the two parameters are determined for the shortest shelf life, namely pH and color (value b). Improvement formula-based beverages with the addition of red betel lime juice can increase preference panelists to drink with the main volatile components are α-curcumene and zingiberene, and shelf life of beverages was 87 days | en |
