摘要: 为探究坚果油籽抗氧化性与其餐后血糖平缓作用的关联,制作含大豆、巴旦木、黑芝麻、亚麻籽的9 种坚果油籽浆,测定其抗氧化指标和对消化酶的抑制率;同时,将坚果油籽浆分别搭配白面包食用,测定13 名健康成年人的餐后血糖水平。结果表明:各混合样品的血糖指数在49~69之间,其中浓亚麻籽豆浆配合白面包组最低,为49。总酚含量、单宁含量、1,1-二苯基-2-三硝基苯肼清除能力和铁离子抗氧化能力与血糖指数、0~60 min和0~120 min内血糖反应曲线下的正面积、血糖峰值及餐后180 min内最大血糖波动幅度极显著负相关(P<0.01)。结论:亚麻籽豆浆稳定餐后血糖的效果最强,其作用可能与其中的抗氧化物质有关。

Abstract: In this study, nine homogenized seed/nut milks were prepared from soybeans alone and in combination with almond, black sesame or flaxseed. Their antioxidant compositions and inhibitory rates on digestive enzymes activities were assessed. Postprandial blood glucose levels of 13 healthy adults after consuming each seed/nut milk together with white bread were measured. Results indicated that glycemic index of each seed/nut milk combined with white bread ranged from 49 (for strong flaxseed + soymilk) to 69. Total phenol and tannin contents, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity and ferric reducing/antioxidant power (FRAP) were significantly negatively correlated with glycemic index, the incremental area under the curve (iAUC)0–60 min and iAUC0–120 min, glycemic peak, and mean amplitude of glycemic excursions at 180 min postprandial (MAGE180) (P < 0.01). In conclusion, flaxseed + soymilk has the strongest inhibitory effect on postprandial blood glucose, which may be related to the presence of antioxidants.
