摘要

为促进黑小麦在糖尿病等慢性病病人饮食中的应用,以农大系列的5种黑小麦为样品,分析了其基础营养成分及活性成分的含量、抗氧化活性和淀粉体外消化情况。结果表明,除淀粉和支链淀粉含量外,其他指标样品间都存在显著差异。农大2201的蛋白质和总膳食纤维含量最高,分别为20.09%(质量分数)和14.11%(质量分数),且清除DPPH自由基和ABTS自由基的能力、铁还原能力也都最强,分别为2.525 mmol TE/kg(TE:trolox equivalent,trolox当量)、6.906 mmol TE/kg、0.535。5种黑小麦的游离酚和结合酚含量分别为0.57～0.68 mg GAE/g(GAE:gallic acid equivalent,没食子酸当量)和0.53～0.57 mg GAE/g,农大3685的总黄酮含量最高,为3.35 mg RE/g(RE:rutin equivalent,芦丁当量)。农大2201的直链淀粉及抗性淀粉含量虽显著低于农大2202和农大H-02,但其估计血糖指数为47.53(未糊化)和74.23(糊化),显著低于后两者。就抗氧化活性和升血糖能力而言,更适合对农大2201做进一步研究,以用于糖尿病等慢性病病人的饮食。

Abstract

To promote their application in the diet of patients with chronic diseases such as diabetes, the contents of basic nutrients and active ingredients, antioxidant activity, and in vitro starch digestibility of five triticale varieties from Agriculture University were analyzed. The results showed that except the contents of starch and amylopectin, other indexes were significantly different among these triticale varieties. No.2201 had the highest contents of protein and total dietary fiber (20.09% and 14.11%, respectively), and the highest scavenging abilities against DPPH and ABTS radicals and ferric iron-reducing power (2.525 mmol TE/kg, 6.906 mmol TE/kg, and 0.535 mmol TE/kg, respectively). The free and bound phenolic contents of the triticale varieties were 0.57-0.68 and 0.53-0.57 mg GAE/g, respectively. No.3685 had the highest content of total flavonoids (3.35 mg RE/g). Although the contents of amylose and resistant starch of No.2201 were significantly lower than those of No.2202 and No.H-02, its estimated glycemic index was 47.53 (with no gelatinization) and 74.23 (with gelatinization), significantly lower than that of the latter. In terms of the antioxidant activity and ability to raise blood glucose, it is more suitable for further study on No.2201 for the diet of patients with chronic diseases such as diabetes.

Key words： triticale; nutrients; antioxidant activity; estimated glycemic index; total phenols; total flavonoids; starch digestibility
