Formula for maintaining postharvest quality and minimizing the spoilage of mango fruit infected with anthracnose under ambient conditions

Anthracnose is the most prevalent and devastating fungal disease both before and after harvesting of mango worldwide (Arauz, 2000). The anthracnose pathogen infects fruit in the field, remains quiescent until the fruit is harvested and starts to ripen. This is the major constraint in the commercialization of fresh mango. Up to this date, this is the first study which evaluated the impact of chitosan based coating with Aloe vera gel and papaya leaf extracts on the postharvest quality of mango fruit infected with anthracnose under ambient storage conditions. After coating and drying, mango was artificially inoculated with Colletotrichum gloeosporioides (105 conidia per mL) and then air-dry, placed in perforated open-top plastic baskets and stored at room condition (average temperature 34.3 ? 2?C, relative humidity 71.8 ? 10%).?The respiration rate, weight loss, color, firmness, vitamin C content and spoilage rate were measured during storage. Results showed that coating formula (0.5% chitosan combined with 0.3 % Aloe vera gel and 0.2% papaya leaf extracts) was considered to be the most effective formula for maintaining postharvest quality and minimizing the spoilage of mango fruit infected with anthracnose under ambient conditions. Further in-depth studies are needed to determine both the action mode in the successful commercialization of this new edible coating in fresh mango fruit industry. SourceNga, N. (2021).
