Antifungal in vitro potential of Aloe vera gel as postharvest treatment to maintain blueberry quality during storage
The postharvest life of most fruit and vegetables is limited by fungus proliferation. The Aloe vera gel was added at different concentrations to test its antifungal potential against five fungi (Rhizoctonia solani, Curvularia hawaiiensis, Botryotinia fuckeliana, Penicillium italicum, Verticillium da...

| Sumario: | The postharvest life of most fruit and vegetables is limited by fungus proliferation. The Aloe vera gel was added at different concentrations to test its antifungal potential against five fungi (Rhizoctonia solani, Curvularia hawaiiensis, Botryotinia fuckeliana, Penicillium italicum, Verticillium dahliae), which cause significant losses in basic agricultural products included in the world's diet: tuber potato, cereals, fruit and vegetables. The best results were for the fungus Verticillium dahlie, with a mycelial growth inhibition of 100% and 70% at 200 and 100 mL/L, respectively. Satisfying results were for fungi R. solani and B. fuckeliana, where the mycelial growth inhibition exceeded 50% in them all at 200 mL/L. Antifungal activity was maintained in B. fuckeliana by lowering the dose to 100 mL/L. The Aloe vera extract at 300 mL/L was applied as a coating in the postharvest treatment to blueberry fruit at 21 °C and 85% humidity. When the experiment ended, the percentage of rotted berries was significantly lower in the treated than in the control. The Aloe vera gel could be considered a promising postharvest treatment to maintain blueberry quality and turgor during storage. |
