Extraction of Total Polyphenols and Dietary Fiber from Mango Peel - As Potential Sources of Natural Phytonutrients

Mango is “King” of fruits. Its production and consumption has gradually increased. As mango peel is not currently being utilized, discarded as waste and becoming source of pollution. The edible pulp makes up to 33 to 85 per cent of the fresh fruit, while the peel and the kernel amounts to 7–24 and 9–40 per cent respectively. It contains total polyphenols (TPP) and total dietary fiber (TDF) which needs to be exploited as natural phyto-nutrients. Hence the present study sought to determine the processing and extraction of total polyphenols and dietary fiber from mango peel. The results revealed that mango peel powder is good source of total dietary fiber, insoluble dietary fiber and soluble dietary fiber was 69.86, 44.23 and 24.63g/100g of MPP; β-carotene 5600 µg/g; total polyphenols 4.5 mg GAE/100g and antioxidant activity 76.96 per cent. These extracts can be incorporated at different levels in formulation of bakery and extruded products which enhanced nutrition and shelf life of food products. Hence the TPP and DF can be commercially exploited as natural anti-oxidants which is useful in nutraceutical formulation in the management of life style disorders
