摘要
【目的】对新育成的黑米两系杂交稻紫两优7206进行营养品质分析,为黑稻良种选育及功能食品研发提供参考价值。【方法】以超级稻宜优673作对照,分析紫两优7206与宜优673的氨基酸、脂肪酸、花色苷和总黄酮等含量差异,以及总抗氧化能力与清除自由基能力的差异。【结果】紫两优7206与宜优673在水分、灰分和脂肪含量方面无明显差异,均检测出17种氨基酸,8种脂肪酸。紫两优7206的必需氨基酸含量高于FAO提出的必需氨基酸模式,其蛋白质含量、总氨基酸与必需氨基酸含量分别比宜优673高7.33%、11.08%和9.71%。紫两优7206比宜优673具有较高的各呈味氨基酸TAV值,丰富了黑米食味品质。2种稻米的饱和脂肪酸(SFA)、单不饱和脂肪酸(MUFA)和多不饱和脂肪酸(PUFA)比值比较接近中国营养协会推荐的“<1∶1∶1”的比例,且均含有人体必需脂肪酸亚油酸与亚麻酸。紫两优7206的花色苷、总黄酮含量,以及总抗氧化能力与清除自由基能力均极显著优于宜优673。【结论】杂交配组选育的紫两优7206较宜优673具有更丰富的营养价值,对功能性黑稻的培育与食品研发具有一定参考价值。
【Objective】Nutritional quality of the newly bred two-line hybrid black rice Ziliangyou 7206 was analyzed for breeding and functional food product development.【Method】Contents of amino acids,fatty acids,anthocyanin,and flavonoids as well as antioxidant capacity and free radical scavenging ability of Ziliangyou 7206,along with Yiyou 673 as the reference,were determined.【Result】The two varieties of rice did not differ significantly in the contents of water,ash,and fat.However,Ziliangyou 7206 had higher contents of protein at 7.33%,the 17 total detected amino acids at 11.08%,and the essential amino acids at 9.71%(which exceeded the FAO standard)as well as higher TAVs on all flavor amino acids compared to Yiyou673.Among the 8 fatty acids in the rice,both varieties of rice had the ratio of SFA(saturated fatty acids)∶MUFA(monounsaturated fatty acids)∶PUFA(polyunsaturated fatty acids)lower than 1∶1∶1 as recommended by the Chinese Nutrition Association,and contained essential fatty acids,such as linoleic acid and linolenic acid.In addition,Ziliangyou 7206 was significantly higher than Yiyou 673 in anthocyanins,total flavonoids,total antioxidant capacity,and free radical scavenging ability.【Conclusion】The hybridized Ziliangyou 7206 was richer in nutritional value than Yiyou 673 and could be promoted for consumption or making functional food products.
