dc.descriptionIn the soft drink market in Ecuador there are not a variety of products of flavored non-caloric concentrates (known as ´Flavor drops´), this gap represents an opportunity in research and entrepreneurship, for low-calorie, low-cost and portable drink alternative for people concerned about their daily calorie intake. This work aims to be an initial effort in the sensory analysis of flavored dilutees, by evaluating two concentrates of different flavors (apple and chewing gum) sweetened with two types of non-caloric sweeteners (sucralose and stevia). The sensory analysis design was perform by an untrained sensory panel to evaluate 18 combinations with different flavor and sweetener concentrations for both flavors. Finally, 36 treatments were analyzed, each treatment was analyzed 3 times for different people, through a simple order preference test, totalizing 108 individuals in the first instance. The two best-rated treatments of each flavor went through an acceptance test trough a 30-person panel, whom indicated which treatment of each flavor was the best. At the same time, two physicochemical characteristics were analyzed in each treatment (viscosity and pH). The variables such as flavor and non-caloric sweetener concentration, and physicochemical characteristics were compared tothe preference level of each treatments through an analysis of variance (ANOVA) with Tukey test at 5%. The results indicated greater preference for treatments sweetened with sucralose (F equals 32.64, p equals less tan 0.0001) in high and medium concentrations (Table 11). None of the other variables showed a significant difference between the different levels, either viscosity, pH (F equals 0.40, p equals 0.754) or flavor concentration (F equals 3.18 p equals 0.0589). The difference by high concentrations of sucralose was statistically significant for the apple flavor (F equals 5.99, p equals 0.0157), but not for the chewing gum flavor (F equals 1.91, p equals 2727). It concludes that sucralose as a sweetener is better perceived by panel and that physicochemical and flavor intensity differences are not perceived. It is recommended to extend the ranges to be tested or try more detailed sensory tests.en
