The effect of volatiles and edible coatings on postharvest avocado (Persea americana Mill.) fruit quality

This experiment was designed to investigate the effects of volatiles and edible coating in avocado fruit physical quality as well as disease incidence.
Eight different types of volatiles (basil, cinnamon, clove, jasmine, geranium, pepper mint, rosemary) were mixed with 1% carboxyl methyl cellulose (1% CMC) and applied to ‘Hass’ avocado fruit.
The treated fruit were then stored in cold temperature (at 5.5°C) for 21 days simulated the export condition and the same fruit were then removed from the cold storage and kept under ambient condition (25°C) for seven days.
Results showed fruit treated with the volatiles and CMC had significantly lower mass loss, respiration rate than control.
Volatiles had an inhibition against Colletotrichum gloeosporioides and Alternaria alternate. The findings reported in this study demonstrated that volatiles and CMC prolong the shelf-life and maintain the overall quality of avocados and suppress diseases during postharvest supply chain.
