摘　　要：为研究不同加工方式对黑小麦面粉抗氧化活性的影响,以普通白小麦为对照,通过测定黑小麦面粉的总酚、总黄酮和花青素这3种抗氧化物质含量以及抗氧化活性,采用回归性分析进行试验论证。结果表明,不同的小麦品种间,黑宝石1号的总酚含量、总黄酮含量、花青素含量,在全麦粉、麦仁粉、普通粉中均为最高,其抗氧化活性在全麦粉、麦仁粉中最高。在不同的加工方式下,4种小麦的总酚含量、总黄酮含量、抗氧化活性均是全麦粉最高,麦仁粉次之,普通粉最低,花青素含量则呈现不一致的趋势。进行回归分析时,总酚、总黄酮含量对抗氧化活性影响均显著,决定系数R^2分别为0.916 5和0.766 4。说明,黑宝石1号是一种较好的黑色食品原料,全麦粉的抗氧化物质含量最高、活性最好。Compared with ordinary white-colored wheat,the effects on antioxidant activity of black wheat flour under different processing methods have been studied by measuring the total phenol content,flavonoids content,anthocyanin content and the antioxidant activity,and regression analysis was used to demonstrate the test conclusion. According to the results,Heibaoshi-1,the kind of wheat cultivar,was the most optimal variety. The total phenol,flavonoids and anthocyanin content of that was the highest among the three kinds of black wheat flour,which was processed under three different processing methods,including the whole wheat flour,the wheat berry flour and ordinary flour. And the antioxidant activity in its whole wheat flour and wheat berry flour was the highest. Under the three different processing methods,the total phenol content,flavonoids content and the antioxidant activity of these four wheat cultivars account for the highest,medium and lowest in the whole wheat flour,wheat berry flour and ordinary flour,respectively. However,anthocyanin content showed an inconsistent trend. From the regression analysis,the total phenol and flavonoids content of these kinds of black wheat flour had significant effects on the antioxidant activity. The coefficient of determination was 0.916 5 and 0.766 4,respectively. In conclusion,Heibaoshi-1 is the most optimal ingredient of black-food,the content of antioxidants and its antioxidant activity of the whole wheat is the highest.
