Aplicación del mapa de preferencia externo en la formulación de una bebida saborizada de lactosuero y pulpa de maracuy

Abstract

Refreshing drinks from whey were developed, varying the concentrations of pulp of passion fruit of 8.0, 11.5 and 15% and sugar 5.0, 7.5, and 10%. The Instrumental evaluation consisted of a determination of pH, acidity and °Brix. The consumer study was carried out with 60 people by applying a five-point hedonic scale. The instrumental-sensory-hedonic relationship is established through the external preferences map. In all drinks pH was greater than 4.0 and acidity greater than 0.2%. Three consumer segments were established and for the formulations with pulp at 8% and 5% and 7.5% sugar, consumers identify them by their pH; the 11.5%: 10% (pulp:sugar) were associated by the °Brix, the 15%:7.5% and 11.5%:7.5% were associated by the acidity. Formulations 15%:7.5%, 15%:10% and 11.5%:10% were preferred by consumers, fact that is related to the sweeter and more intense flavor of this formulation.
