Resumen
Antecedentes y Objetivos: Las bebidas de Annona muricata se utilizan ampliamente en la medicina tradicional para tratar diferentes padecimientos; sin embargo, han sido poco caracterizadas fitoquímicamente y se consumen como bebidas azucaradas, y pueden contribuir a enfermedades no trasmisibles, entre ellas la obesidad. El objetivo de este trabajo fue obtener y caracterizar una bebida sensorialmente aceptable a partir de un extracto de hojas y pulpa de A. muricata.
Métodos: Se utilizó un diseño de mezcla para formular nueve bebidas, combinando diferentes proporciones del extracto acuoso de hojas y pulpa de A. muricata. Estas bebidas se sometieron a una evaluación fisicoquímica y sensorial. A partir de estos resultados, se seleccionó una bebida para caracterizarla por espectrofotometría y compararla con una bebida infusionada y otra comercial. Además, se analizó la composición fitoquímica de la bebida seleccionada mediante cromatografía de ultra alta resolución acoplada a espectrometría de masas y cromatografía líquida de alta resolución acoplada a un detector de matriz de fotodiodos.
Resultados clave: La bebida seleccionada se formuló con 25% de pulpa, 50% de extracto de hojas y 25% de agua; además, presentó un valor de 7.63 °Brix, un pH 3.42 y una acidez de 0.40%. Esta bebida fue hasta tres veces superior en compuestos bioactivos respecto a las bebidas infusionada y comercial. Se cuantificaron catorce compuestos fenólicos y dos acetogeninas, mientras que se identificaron provisionalmente dos alcaloides (coclaurina y reticulina) y quince acetogeninas.
Conclusiones: La combinación de extracto de hojas y pulpa de A. muricata es una alternativa vital para obtener una bebida sensorialmente aceptable que contiene compuestos bioactivos con potencial acción medicinal, ya que los compuestos fenólicos, alcaloides y acetogeninas presentes en la bebida podrían tener actividades biológicas eficientes en la prevención de enfermedades crónicas degenerativas.
