Waste-to-wealth; nutritional potential of five selected fruit peels and their health benefits: A review

Waste-to-wealth is a notion describing the process of transforming waste, an end product to get rid of, into potential value-added products. The total global food waste predicted be approximately one third edible parts manufactured for human consumption, amounting about 1 - 3 billion tonnes per year, which equivalent production in sub-Saharan Africa; 842 million people world do not have enough eat.

This review sought examine nutritional, benefits orange (Citrus sinensis), papaya (Carica papaya), pineapple (Ananas comosus), watermelon (Citrullus lanatus) banana (Musa sapientum) peels termed valorized nutrient-rich products needed pharmaceutical industries. nutritional profile (gkg-1) dry weight revealed crude protein ranged from “[watermelon 0.55 18.96]” fiber 0.21 42.22]”. mineral analysis (mg/kg-1) comprised Ca “[pineapple 8.30 162.03]”; Fe “[banana 15.15 45.58]”; Zn 0.033 14.04]”. All had good antioxidant potential. Glycemic index 19 32]”; estimated glycemic load “[Watermelon 1.93 Orange 27.51]”. Fruit can minimized by creating awareness on valorization peels.   Key word: fruit peels, analysis, antioxidant, benefits.
