Conteúdo: | Nectars are beverages formulated with the juice or pulp of one or more fruits, plus water and sugar in concentrations resulting in a \"ready-to-drink\" product. Recently the market for such products has greatly expanded. Fruit blends present a series of advantages, such as the combination of different aromas and flavors and the sum of their nutritional components. The objective of this study was to develop a nectar based on papaya and passion fruit pulps, fortified with the vitamin C present in West Indian cherry pulp, optimizing the formulation using sensory consumer tests and Response Surface Methodology. Eleven formulations were elaborated using different concentrations of papaya and passion fruit pulps and sucrose, and maintaining the concentration of West Indian cherry pulp constant. The sensory tests were carried out with 22 consumers using a structured 9-point hedonic scale to evaluate overall acceptance and a 5-point intention to buy scale to evaluate this attribute. The acceptance means were submitted to a regression analysis, first calculating a polynomial quadratic equation and testing the lack of adjustment and significance of each parameter. A predictive model was adjusted considering only those parameters where p?0.05, and a Response Surface drawn. The Response Surface indicated that the sensory acceptance of the nectars was positively affected by increases in the concentrations of papaya pulp and sucrose. The product presented good sensory acceptance suggesting good commercial potential.
