摘要:

【目的】 分析不同粒色藜麦营养成分、抗氧化能力以及体外消化和血糖生成指数差异,为提供藜麦加工品质及功能活性开发提供理论依据。【方法】 以白色、红色、黑色藜麦为研究对象,比较不同粒色藜麦营养成分、糊化特性、抗氧化能力,并通过口腔-胃-小肠三段式体外模拟消化评价3种藜麦的体外消化速率和预估血糖指数(eGI)差异性。【结果】 3种藜麦灰分、淀粉、直链淀粉、支链淀粉、水溶性蛋白含量存在显著性差异(P<0.05),糊化特性中低谷黏度、最终黏度、稀懈值和回生值,黄酮含量等指标之间均存在显著差异(P<0.05)。三色藜麦中黄酮提取液和水溶蛋白提取液具有较好的抗氧化活性。红色藜麦黄酮和水溶性蛋白提取液对DPPH·和ABTS+·的清除抗氧化能力高于其他藜麦提取液。黑色藜麦体外消化率曲线增速比白色藜麦慢。预估血糖指数(eGI)为(48.32~54.21) <55,藜麦是低eGI食物。藜麦eGI值排序为:红色藜麦(48.32)<黑色藜麦(48.99)<白色藜麦。【结论】 不同颜色藜麦的营养特性,糊化特性、抗氧化活性、抗消化特性以及血糖生成指数存在显著性差异,其中白色藜麦的糊化特性比黑、红色藜麦好。红色藜麦的抗氧化和抗消化特性强于白、黑色藜麦,血糖生成指数最低。

Abstract:

【Objective】 To analyze the nutrient quality, antioxidant activity, and the in vitro digestion rate and expected glycemic index (eGI) of different colored quinoa in the hope of providing theoretical basis for the development of quinoa processing quality and functional properties. 【Methods】 Three kinds of quinoa seeds, white, black and red were selected as subject and used to compare the nutrient composition, pasting properties, antioxidant capacity. Afterwards, their difference of in vitro starch digestibility and expected glycemic index (eGI) were determined by using three-dimension of oral-stomach and small intestine. 【Results】 There were significant differences (P<0.05) in the basic nutrient components, total flavone contents, pasting properties such as trough viscosity, final viscosity, breakdown, and setback value of three quinoa varieties. The flavonoid extract and water-soluble protein extract of tricolor Quinoa had excellent antioxidant activity. In vitro antioxidant experiment results showed that ABTS+· scavenging activity and DPPH· scavenging activity of the total flavonoids extraction and protein extraction from red quinoa ware stronger than that of the other quinoa extraction.The results of in vitro digestion showed that the growth rate of in vitro digestibility curve of red and black quinoa starch was slower than that of white quinoa. The estimated glycemic index (eGI) of quinoa was (48.32~54.21) <55, indicating quinoa as a low-glycemic index(eGI) food. Quinoa eGI values were ranked as follows: red quinoa (48.32)<black quinoa (48.99)<white quinoa(54.21). 【Conclusion】 There were significant differences in the nutritional properties, pasting properties, antioxidant activity, digestive properties and glycemic index (eGI) between the different color’s quinoa. The pasting property of white quinoa were better than black and red quinoa. The antioxidant activity and antidigestive properties of red quinoa were stronger than white, black quinoa, with the lowest glycemic index (eGI).

Key words: tricolor Quinoa; nutrient components; antioxidant activity; in vitro digestibility; glycemic index (eGI)
