Abstract: Pumpkin pomace obtained from cultivar (Cucurbita moschata Duch) was analyzed for their chemical composition and functional properties. Pumpkin pomace powder contained more than 50 mass % of total dietary fibre and showed high hydration properties such as water holding capacity (5.70 g. g–1) and swelling capacity (10.26 cm3. g–1). The effect of pumpkin pomace incorporation to wheat dough by replacement of wheat flour with pumpkin pomace (5 or 7.5 %) on physical properties (volume, volume index, width, thickness, spread ratio) and sensory parameters (appearance, hardness, taste, odor, overall acceptability) of cracker were evaluated. The results indicated that the addition of higher amount (7.5 % mass) of pumpkin pomace powder negatively affected the volume, volume index, spread ratio and reduced their overall acceptance. Pumpkin pomace is a good source of ash and dietary fibres and may be incorporated into baked goods as a functional ingredient.
