Evaluación de diferentes tratamientos hidrotérmicos para el control de la podredumbre ocasionada por Fusarium sp. durante la poscosecha de piña (Ananas comosus var. MD-2).

Abstract

This study evaluates the effect of different hydrothermal treatments, as alternative methods for the control of rot caused by Fusarium sp. during post-harvest period of pineapple (Ananas comosus var. MD-2). During the post-harvest period of the fruit, it determined that the treatments control with fungicide (CK + F) and hydrothermal at 40 ºC for 1 minute showed the higher antifungal activity with a reduction of rot caused by Fusarium sp. of 41.71% and 22.61%, respectively. Later, the effect of the different hydrothermal treatments on the physical-chemical quality of the pineapple was study. The results let show that the heat treatment at 40 ºC for 1 minute didn’t get a negative effect at weight loss, translucency, skin color, or Chemical characteristics (TSS, Titratable acidity and pH). However, the firmness and appearance of the fruit crown were altered during post-harvest period. The study concluded with the evaluation of the effect of hydrothermal treatment at 40 ºC for 1 minute on the sensory characteristics of pineapples during the post-harvest period and it found that the hydrothermal treatment didn’t affect it.
