Insoluble fiber-rich fractions (FRFs), including insoluble dietary fiber, alcohol-insoluble solid, and water-insoluble solid, were isolated from the peel of Citrus sinensis L. cv. Liucheng. We found that these three FRFs could effectively adsorb glucose, retard glucose diffusion, and inhibit the activity of alpha-amylase to different extents. These mechanisms might create a concerted benefit in decreasing the rate of glucose absorption and eventually lower the concentration of postprandial serum glucose. The potential hypoglycemic effects of these FRFs suggested that they could be incorporated as low-calorie bulk ingredients in high-fiber foods to reduce calorie level and control blood glucose level.
从不溶性纤维含量丰富的组分（FRF）中分离出了包括不溶性膳食纤维、醇不溶性固体和水不溶性固体在内的成分，这些成分取自柳城脐橙（Citrus sinensis L. cv. Liucheng）的果皮。我们发现，这三种FRF能够在不同程度上有效吸附葡萄糖、延缓葡萄糖扩散并抑制α-淀粉酶的活性。这些机制可能在降低葡萄糖吸收速率并最终降低餐后血清葡萄糖浓度方面产生协同效益。这些FRF的潜在降血糖作用表明，它们可以作为低热量的填充成分添加到高纤维食品中，以降低热量水平并控制血糖水平。
