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.

柑桔皮中不溶性膳食纤维的分离与鉴定

食用膳食纤维具有许多有益健康的作用。在本研究中，使用酶重分析法从Kinnow果皮中分离了膳食纤维，收率为47±0.23％。研究了kinnow果皮和分离的膳食纤维样品的各种理化特性。每克纤维样品的持水量（WHC）和持油量分别为6.92 g和1.26 g。还对Kinnow果皮粉（0.74％氮，29.60％碳，6.70％氢和62.97％氧）和提取的纤维（41.78％碳，6.42％氢和51.80％氧）进行了元素分析。SEM和FTIR测试用于检查膳食纤维结构的变化。从元素分析和FTIR的结果可以明显看出，提取的纤维不含蛋白质。
