ABSTRACT: Mango fruits have high nutritional values due to their various components. Post-harvest operations are accompanied by the generation of high quantities of by-products that are poorly recovered. This study investigated the biochemical potential of mango biowaste for sustainable feed production and renewable energy generation. Biochemical parameters of the biowastes from five cultivars were determined using standard methods. Bioreaction modling was curried out by experimental design method. Solid mango biowaste had a moisture content of 81.50 ± 2.25%, a Brix index of 15.31 ± 2.86˚ Brix, a pH of 4.23 ± 0.38 and a total acidity of 3.51 ± 0.74% MS. The proximate composition (w/w, dry matter basis, DM) was 2.15 ± 0.61% fat, 3.63 ± 0.88% proteins, 3.42 ± 0.54% ash and 90.80 ± 1.38% sugars with an energy value of 397.03 ± 3.71 kcal/100g. Levels of minerals of metabolic importance such as potassium, phosphorus, magnesium, manganese, zinc, and copper were 1288.93, 403.11, 55.32, 2.921 ± 0.18, 0.617 ± 0.15 and 0.018 ± 0.02 mg/100g DM, respectively. Levels of phenolic compounds were 80.81 ± 13.53 mg EAG/g DM, flavonoids 27.65 ± 7.65 mg Equiv. quercetin/g DM, antioxidant compounds 8.82 ± 0.18 mg Equiv. ascorbic acid/g DM, reducing sugars 81.06 ± 22.46 mg Equiv. D-glucose/g DM, vitamin C 2.04 ± 1.12 mg/g DM and beta-carotene 1.88 ± 1.18 mg/g DM. Bioreaction modling showed that substrate prepared with 40% of MBPs and 0.1% of SBF is the most optimal. Further optimisation could be achieved by enriching this formula with various external mineral sources and ammonium sulphate or yeast extract. Solid mango biowaste has interesting biochemical compounds of nutritional interest that can be recovered and economically valorized.
