Inhibitory effect of essential oils against Colletotrichum gloeosporioides and Rhizopus stolonifer in stored papaya fruit and their possible application in coatings

摘要: Abstract The aim of this study was to evaluate the fungicidal effect thyme and Mexican lime essential oils studies against Colletotrichum gloeosporioides Rhizopus stolonifer, determine possibility incorporating them in edible coatings control postharvest diseases papaya fruits. For vitro studies, both were tested their on mycelial growth C. R. stolonifer during given incubation times. vivo tests, fruit dipped before after inoculation. Non-inoculated fruits similarly treated. A further experiment carried out by dipping papayas a coating formulated with oils. Results indicated that more evident than oil. oil, concentrations up 0.060% stopped for stolonifer. Papaya experienced reduced decay caused 50% 40%, respectively, compared 100% infection observed non-treated papayas. It also concentration not key factor reducing development these two fungi as it occurred studies. In immersed mesquite gum emulsion oils, possible reduce disease incidence at 0.1% 0.5%, respectively. Conclusion Thyme demonstrated inhibitory effects evaluations over storage rots fruit. Incorporation gum-based gave excellent diseases. Significance Impact Study Control using synthetic fungicides is becoming increasingly difficult. are considered GRAS compounds. This investigation highlights potential anthracnose rot papaya. We confirmed mesquite-based accomplished what expected film material: microorganism inhibition shelf-life extension
