To evaluate the proximal composition of pulp, peel and isolated fiber of fully ripe “Ataulfo” mango, as a potential sources of bioactive components against factors associated with the metabolic syndrome. Fully ripe Ataulfo mangos were harvest from Sinaloa, Mexico. Pulp and peels were separated, lyophilized and grounded. Lyophilized peels were whashed using a 80% ethanol and acetone solution to obtain isolated fiber. Proximal analysis was performed using the official AOAC methodologies for protein, fat, ash and soluble and insoluble dietary fiber. Glucose, fructose and saccharose were analyzed using enzymatic method. Folin-Ciocaltieu assay was used to evaluate total phenolics, total flavonoids were measured by spectrophotometry. Vitamin C and b-carotene were determinated by UV-Vis chromatography. Neutral sugars were measured by alditol acetates method. Data analysis was done using SAS statistic software. Great differences in the bioactive composition between pulp, peel and isolated fiber were observed. Mango pulp had 71% and 10.1%, while isolated fiber 0.9 and 81% of free sugars and dietary fiber respectively. Mango peel exhibed a balanced free sugar (38%) and fiber quantities (41%), and also the highest amounts of phenolics and total flavonoids, b-carotene and vitamin C. Soluble and insoluble fiber ratio was around 1 in pulp, peel and isolated fiber, which is considered as good quality dietary fiber. Glucose, arabinose and galactose were major neutral sugars, and revealed probable structure type arabinogalactan, b-glucan or arabinan. Mango peel had the most abundant content of dietary fiber, total phenolic and flavonoids, vitamin C and β-carotene, and the lowest amount of free sugars compared to mango pulp. According to the reported literature, our products could have bioactive components against the metabolic syndrome related factors, and even better, mango peel had less free sugars than mango pulp. Mango peel seems to have the major presence of bioactive compounds compared to mango pulp, After this proximal analysis, mango peel can not longer be considered as a waste product. More studies need be done in order to probe the effectiveness of the bioactive components found in mango peel associated with the control of the most important risk factors related to the metabolic syndrome.
