GREEN ACTIVE COATING FROM Abelmoschus esculentus INCORPORATED WITH PROPOLIS EXTRACT: EFFECTS ON QUALITY IN FRESH FRUIT

Le résumé fourni par la source

Losses related to the food production chain amount to thousands of kilograms per year. These losses may be related to poor storage conditions. Therefore, the objective of this research was to develop a natural coating based on a biopolymer extracted from Abelmoschus esculentus, incorporated with propolis extract as a natural additive. The coating was applied to strawberries to analyze its efficiency regarding its shelf life and potential antifungal activity. The mucilage was extracted, and its yield was evaluated and characterized according to FTIR, SEM, TGA, contact angle, and surface tension analyses. Two types of coatings were developed using the obtained mucilage: Coating OMC, consisting of water and mucilage (1% w/v), and coating OMP, consisting of mucilage and 15% aqueous propolis extract. Both coatings showed inhibitory properties against the mycelial growth of the fungi Aspergillus flavus and Aspergillus niger. The coating applied to the strawberries helped maintain their attractive appearance, maintaining their natural color throughout the experiment. Okra mucilage coatings incorporated with propolis showed promise for storage and shelf-life extension of fresh fruit.
