Objective: The aim of this thesis was to characterizing nutritionally a nectar elaborated from whey and Myrciaria dubai (camu - camu) sweetened with Stevia rebaudiana (stevia).Materials and Methods: It was an experimental laboratory study, where was evaluated the effect of the dose of whey (30%, 50% and 70%) and camu camu pulp (70%, 50% and 30%) on its sensory and nutritional properties. Results: The physical-chemical results of the three formulations got the quality standards for fruit beverage. The sensory evaluation was performed with 79 untrained panelists, who determined that the formulation contained 70% of camu-camu pulp and 30% of of whey it was the one that presented the highest score in the sensory evaluation being only 2.5 / 7 on a hedonic scale, so it is recommended to improve the formulations. Discussion: The physical chemical analysis of the formulated beverages showed that the whey-based nectar with camu camu showed a low calorie level in 100 grams of product, an average of 23 Kcal / 100g, 5.3% carbohydrates, 0.4% of protein, 0.1% fat, 93.8% water, 0.4% ash. The microbiological analysis indicated that they satisfy the sanitary norm that establishes the microbiological criteria of quality for nectars, which guarantees the safety of the product. We realized the analysis of vitamin C in the camu-camu pulp, in the mixture of the beverage, before the pasteurization and after the pasteurization, being these: 195,8mg / 100g, 180,7 mg / 100g, 168,3mg / 100g respectively, evidencing that in the final product there is a decrease of about 14,04% with respect to the initial content of camu -camu. Conclusion: The nutritional characteristics of the nectar made from whey, camu camu sweetened with Stevia presented a slight increase in the value of proteins (0.3g / 100ml) than commercial nectars (0g / 100ml) that are sold in the country, but it stands out Due to its high content of vitamin C (168.3mg / 100ml), however, the incorporation of whey did not result in a clear sensory acceptability in young people, therefore the hypothesis that whey increases sensory acceptability is rejected. Likewise, the hypothesis that increases the nutritional quality of nectar in comparison with similar beverages that are sold in the national market is accepted.
