Abstract

 he present study was aimed for examine the bioactive compounds and antioxidant potential of three fruits by-products (banana peels (BPP), pomegranate (PGPP) and prickly pear PPP) in Egypt. The total dietary fiber content for all fruit by - products PGPP – PPP - BPP was ranged 26.06 - 34.76   g.100g-1, total phenolics was 516 -1267 mg GAE.100 g-1 and total carotenoids were 146.25- 219.11 mg.100g-1. The BPP recorded the highest content of total dietary fiber followed by PPP, mixture and PGPP respectively while PPP the highest in carotenoids and PGPP registered high content in Total phenolic. The fruits by-product PGPP- PPP- BPP extracts indicated that large differences in antioxidant activity (AA, %) was ranged 74.96 - 89.16 %. PGPP showed strong antioxidant activity followed by mixture, BPP and PPP respectively. The results showed that BPP recorded high content of protein, crude fiber and ash 3.64, 28.43 and 3.42 respectively While PGPP recorded high level of Moisture 10.76 and PPP have the highest content of Carbohydrates73.87. In conclusion, result of the current study disclosed that fruits by-products (PGPP-PPP- BPP) can be useful sources of valuable bioactive compounds and antioxidants expand their main uses in nutritional, curative applications and many health benefits.
