Enzyme-treated orange pomace alters acute glycemic response to orange juice.


ABSTRACT: 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. Overall, this study demonstrated that adding 5?g of fiber from orange pomace into a serving of OJ attenuated the postprandial glucose response.
