The goal of the present study was to determine the impact of the addition of enzyme-treated orange pomace to orange juice on postprandial glycemic response. Ten healthy subjects (aged 27.9 ± 7.7 years, body mass index 22.1 ± 1.1 kg m-2) participated in a randomized, 2-arm, cross-over clinical trial to test the glycemic response to 100% orange juice (OJ) or 100% orange juice with 5 g of enzyme-treated orange pomace fiber (OPF). Blood samples were collected and glucose and insulin concentrations were measured at fasting (0 min) and every 15 min for 2 h after consuming the study juice products. Analysis of the 2 h incremental area under the curve (iAUC0-2h) indicated a significant reduction in blood glucose after ingesting the OPF juice compared to the OJ, p = 0.02. Peak glucose concentrations were also lowered after the OPF juice compared to the OJ, p < 0.05. No significant difference was observed in insulin responses between treatments, p > 0.05. Overall, this study demonstrated that adding 5 g of fiber from orange pomace into a serving of OJ attenuated the postprandial glucose response.

酶处理的橙果渣改变了对橙汁的急性血糖反应。



本研究的目的是确定在橙汁中添加酶处理的橙果渣对餐后血糖反应的影响。十名健康受试者(年龄 27.9 ± 7.7 岁,体重指数 22.1 ± 1.1 kg m-2)参加了一项随机、2 臂、交叉临床试验,以测试对 100% 橙汁 (OJ) 或 100% 橙汁 (OJ) 的血糖反应% 橙汁与 5 克酶处理橙果渣纤维 (OPF)。采集血样,并在空腹(0 分钟)时测量葡萄糖和胰岛素浓度,并在食用研究果汁产品后每 15 分钟测量一次,持续 2 小时。对 2 小时曲线下增量面积 (iAUC0-2h) 的分析表明,与 OJ 相比,摄入 OPF 汁后血糖显着降低,p = 0.02。与 OJ 相比,OPF 果汁后的峰值葡萄糖浓度也降低,p < 0.05。治疗之间的胰岛素反应没有观察到显着差异,p > 0.05。总体而言,这项研究表明,在一份橙汁中添加 5 克橙果渣纤维可减弱餐后血糖反应。
