ABSTRACT

Introducción: El estudio se centró en obtener pulpa liofi-lizada de maracuyá manteniendo su calidad sensorial y nu-tracéutica. Objetivo: Se evaluaron diferentes concentraciones deaglomerantes en propiedades físico-químicas, solubilidad, co-lor, vitamina C y polifenoles. Material y métodos: Se examinó la cinética de secado porliofilización en un diseño factorial 3x3, los aglomerantes (gomaarábiga, almidón de arroz, pectina) y sus concentraciones im-pactaron fenoles totales, vitamina C, color y solubilidad. Resultados: Destacaron la goma arábiga al 1.5% y la pec-tina al 1.0% para preservar sabor y color, y la pectina al0.75% mostró alta velocidad de secado. Conclusión: La goma arábiga sobresalió en fenoles tota-les, color y solubilidad, mientras que la pectina conservó me-jor la vitamina C.(AU)


Introduction: The study focused on obtaining freeze-dried passion fruit pulp while maintaining its sensorial and nu-tritional quality. Objective: Different concentrations of binders were eval-uated for physical-chemical properties, solubility, color, vita-min C and polyphenols. Methodology: The freeze-drying kinetics were examinedin a 3x3 factorial design, the binders (gum arabic, rice starch,pectin) and their concentrations impacted total phenols, vita-min C, color and solubility. Results: They highlighted gum arabic at 1.5% and pectinat 1.0% to preserve flavor and color, and pectin at 0.75%showed high drying speed. Conclusion: Gum Arabic excels in total phenols, color andsolubility, while pectin preserves vitamin C better.(AU)
