Resumen
Consumers demand the use of eco-friendly fungicides to treat fruit and vegetables and
governmental authorities have unauthorized the application of chemical antifungals for the efficient
control of sour rot. In the present research, the microwave irradiation (MW) method was used to
encapsulate thymol into 2-hydroxylpropyl-beta-cyclodextrin (HP-β-CD) and the effect of these HPβ-CD on controlling sour rot in citrus fruit, caused by Geotrichum citri-aurantii, was evaluated.
Amounts of 25 and 50 mM of HP-β-CD-thymol were used, and compared with propiconazole, to
control the decay of inoculated lemon fruit. The treatments were performed in curative and
preventive experiments. The incidence and severity of Geotrichum citri-aurantii in 25 and 50 mM HPβ-CD-thymol-treated fruit were reduced in both experiments. The preventive 50 mM HP-β-CDthymol treatment showed the best effect, reducing the sour rot, respiration rate and fruit weight loss
during storage at 20 °C. HP-β-CD-thymol increase...
