Effects of different comercial coatings on postharvest citrus fruit quality for export

The use of fruit coatings aims to avoid dehydration, minimize the occurrence spots in peel and weight loss as well extend postharvest life maintaining appearance. objective this study was evaluate effect different quality, acetaldehyde ethanol production mandarin orange varieties, during storage. With that aim, fruits with or without degreening fungicide treatment, were treated experimental conditions commercial Brillaqua UE-Mercosur UEJ-Mercosur, Citrosol AUE Sunseal, Concentrol AC36, repeating evaluation more promising treatments together UEF6-Mercosur, AKUE y Tecnidex Teycer-GLK. In both experiments, stored for 6 weeks at 1±0.5 ºC plus 7 days room temperature simulating shelf life. External internal quality evaluated moments None affected firmness, external negatively compared control BRIUE. most their application citrus storage 1 Teycer-GLK, showing an acceptable brightness level, good appearance superior quality. AC36 not discarded alternatives since they presented brightness, levels after
