The present research aims to include the native Peruvian fruits in the design of drinks with low caloric content. For this purpose, four types of mixed nectares are proposed: A (Pineapple, Camu-camu, Apple and extract of purple Maize), B (Manzana, Sanky and Camu camu), C (Passion Fruit, Mango and Aguaymanto) and D Pineapple and Camu-camu), with a sucrose substitution factor by Stevia of 50%, obtained by a relative intensity of sweetness test. For the selection of the nectar types, a preference classification test was used with 120 panels composed of 18-21 year old students and the data were analyzed with the Friedman test and the Kramer test (α = 0.05), where Obtained formulation A, consisting of 27.9% pulp mixture, 10% corn extract, 57.6% water, 4.06% sugar, 0.19% acidulant, 0.05% Antioxidant, 0.12% stabilizer and 0.05% Stevia powder, as the most preferred nectar. To evaluate its quality, the proximal chemical, physicochemical, microbiological, sensorial acceptability tests were tested using a hedonic scale of 9 points, and its useful life through accelerated tests, using the quality parameters as an indicator of deterioration. From the quality tests, a pH of 3.37 ± 0.08, Brix 6.53 ± 0.30, acidity 0.2868 ± 0.0061, density 1.035 ± 0.006, fats 0.4%, carbohydrates 8.8%, proteins 0.4%, fiber 0.4%, vitamin C 57.4 Mg / 100 g and no caloric content of 40.4 Kcal / 100 g. For a greater acceptability of the drinks it is established that the percentages of incorporation of the fruits are equal to or less than 7.40% in camu-camu, 20.14% in aguaymanto, and 16.67% in sanky, the options may vary depending on the fruits that accompany The formulation. Also, the presence of stevia as a substitute for sucrose by 50% did not give a significant difference in sweetness.Autor(es):
