Abstract: Dietary fibre consumption offers numerous health beneficial effects. In the present study dietary fibre was isolated from kinnow peel using enzymatic gravimetric method with 47 ± 0.23% yield. Various physiochemical properties of kinnow peel and the isolated dietary fibre samples were studied. The water holding capacity (WHC) and oil holding capacity were 6.92 g and 1.26 g per g of the fibre sample respectively. Elemental analysis was also done for kinnow peel powder (0.74% nitrogen, 29.60% carbon, 6.70% hydrogen and 62.97% oxygen) and for the extracted fibres (41.78% carbon, 6.42% hydrogen and 51.80% oxygen). SEM and FTIR tests were used for examining the changes in the structures of dietary fibres. From the results of elemental analysis and FTIR, it was clear that the extracted fibre does not contain proteins. Rheology of the extracted dietary fibres exhibit non-Newtonian behavior and shear thinning properties.
