本文对比分析了萌芽半糙米、糙米、半糙米和精米共4种不同类型稻米的蛋白质、粗脂肪、维生素、矿物质等主要营养成分及其总酚、总黄酮、单体酚等活性物质含量和总抗氧化能力。结果表明,萌芽半糙米的VE、总酚、总黄酮、单体酚香豆酸和阿魏酸的含量及总抗氧化能力较糙米高出40~100%,较半糙米高出60~130%,较精米高出120~440%,其中VA、VB1、VB2和VE的含量较精米提高3~15倍,总酚、总黄酮、香豆酸和阿魏酸含量及总抗氧化能力高于精米1~4倍,其蛋白质、粗脂肪、和矿质元素含量均较精米高30~290 %。由此可见,萌芽半糙米是一种营养价值较高的全谷物食品。

[Abstract]
The main nutritional components of protein, crude fat, vitamins and minerals were compared and analyzed in four different rices , which were germinated semi-brown rice, brown rice, semin-brown rice and milled rice. Meanwhile, the content and total antioxidant capacity of active components of total phenolics, total flavonoids and monomeric phenolic contents were investigated. The results show that the contents of VE, total phenolics and flavonoids, coumalic acid and ferulic acid and their total antioxidant capacity of germinated semi-brown rice are 40% to 100% higher than those in brown rice , 60~130 % higher than semi-brown rice and 120~440 % higher than milled rice. The contents of VA, VB1, VB2和VE in germinated semi-brown rice are increased 3 to 15 times than those of milled rice.. And the contents of total phenolics, flavonoids, coumalic acid and ferulic acid and their total antioxidant capacity are 1 to 4 times higher,than those of milled rice. Moreover, the contents of protein, crude fat, and minerals content are 30~290% higher in geminated semi-brown rice than those of milled rice. From those, it can be seen that the geminated semi-brown rice is a kind whole grain food .with high nutrition value.
