Abstract: The objective of the present study was to investigate the physicochemical and phytochemical properties of the gum exudates of Lannea coromandelica, develop a wax from the exudates to be used as a fruit coating and to check the variation of physicochemical characteristics of a moderate respiratory fruit after applying the waxes. The proximate composition was determined by using AOAC methods. Antioxidant capacity was determined using the free radical 2, 2- diphenyl- 1-picrylhydrazyl (DPPH) method, The total phenolic contents were measured using Folin-Ciocalteu reagent assay according to the method described by Singleton et al., (1999) with some modifications. The gum was observed under Scanning electron microscope (SEM) and FTIR was carried out for gum exudates. The effect of waxing was observed by applying the Hik wax on sour banana. Color, hardness, moisture content, titratable acidity and pH variation of sour bananas treated with wax were observed with time (Days).
