DETERMINACIÓN DE LA CONCENTRACIÓN ÓPTIMA DE EDULCORANTE STEVIA EN MERMELADAS DE UVA BAJAS CALORÍAS A TRAVÉS DEL PUNTO DE CORTE SENSORIAL OBTENIDO DE LAS ESTADÍSTICAS DE ANÁLISIS DE SUPERVIVENCIA

The present study studies the ideal concentration of natural sweetener Stevia in jams developed from grapes reduced in their natural carbohydrates, through a Central Location Test, from a panel of 123 consumers from the city of Olavarria (Argentina), in an age range of 15-65 years. Each of the consumers received 6 samples of jam with different concentrations of Stevia sweetener. For each sample, consumers had to answer according to their degree of acceptability if: "It is less sweet than I like it", "It is sweet as I like it" or "It is sweeter than I like it". The optimal concentration was 3.74% (w / w), which means that 5.61 g of the Stevia sweetener is equivalent to 100 g of common sugar, for which purpose the Cut Point technique was applied applying the Statistical Survival Methodology.
