Development of Energy Drinks with Orange Juice (Valencia frost)

Abstract

The aim of this study was developed an energy orange juice drink with an addition to caffeine and taurine. For that, comparison of means tests were performed for four treatments, corresponding to juice added with caffeine 0.032% concentration, juice added with taurine 0.4% concentration, juice added with caffeine and taurine mixture 0.032% and 0.4%, respectively and one control, each with six replicates. The drinks were packed in low density polyethylene bags and stored at 4°C. The soluble solids (°Bx), pH, acidity, expressed as the percentage of citric acid, instrumental color and browning index and sensory characteristics (color, odor, appearance and taste) were evaluated at 0, 5, 10, 15, 20, 25 and 30 days. All the evaluated beverages presented suitable conditions for the consumption until the day 30, in addition, the added caffeine and taurine mixture treatment was which presented the best sensorial characteristics (appearance, color, odor and flavor). The acidity of all treatments increased during storage, is the largest increase for taurine treatment that was 1.37% to 2.1%, the pH decreased from 3.3 to 3.2 for all treatments except the Control; and soluble solids remained constant. In addition, the energizing agents did not affect the goldenness index of the beverages.
