Development Of Dragon Fruit Peel-based Snacks Bar
This study was aimed to analyse the nutritional composition and physicochemical properties of snack bar formulated with different levels of dragon fruit peel (DFP) powder. Snack bars were prepared with the addition of increasing amount of DFP in 0g, 5g, 10g and 15g respectively. Proximate compositio...
