La industrialización de la palta genera grandes cantidades de desecho de cáscara y semilla que representan el 18 y 13 % del peso total del fruto respectivamente, que generalmente son eliminados. Estudios han demostrado que estos subproductos poseen altos contenidos de compuestos fenólicos que son beneficiosos para la salud humana, es por ello que ha generado mayor interés para la industria alimentaria, cosmética y farmacéutica; las cuales han desarrollado y empleado numerosos métodos de extracción con la finalidad de recuperar la mayor cantidad de dichos compuestos. En esta revisión se describe la composición proximal y fenólica de la cáscara y semilla de palta. Además, se hace énfasis en las variables de proceso de las tecnologías convencionales (soxhlet y maceración) y emergentes (extracción asistida por ultrasonidos o microondas y extracción por líquidos presurizado...

Red pitahaya (Hylocereus guatemalensis) peel is a by-product of pulp and juice production, which is often underutilized due to the lack of scientific information on how to preserve it in a manner that minimally affects its bioactive compounds. The objective of this study was to evaluate the effect of hot air drying on the total phenolic content (TFC) and antioxidant capacity (AC) by DPPH radical scavenging (%) of red pitahaya peel. The peel was separated from the pulp, cut into four equal parts and subjected to hot air drying. Drying was carried out at temperatures of 40, 50, 60, 60, 70, 80 and 90 °C for a period of 1 080 min. The peel was ground (particles < 850 μm), the extract (50 mg/mL) was obtained using 80% methanol as solvent, and the TPC and AC were determined. The influence of drying temperature was significant (p<0.05) on TPC and AC as drying temperature increase of 40 ...
