| 摘 要： | 测定生态葛根奶中矿物质的含量,探讨其营养价值.硝酸-高氯酸消解样品,用火焰原子吸收光谱法测定生态葛根奶(饲喂葛根4周)及未饲喂葛根的对照组奶样中铜、锌、铁、钙、镁的含量,应用F检验、SNK法和LSD-t检验对结果进行统计分析.测定方法的精密度介于0.04％～0.7％,平均回收率介于93.70％～106.20％.试验组和对照组比较:铜的含量差异没有统计学意义(F=2.702,P＞0.05)；锌的含量差异没有统计学意义(F=1.684,P＞0.05)；钙的含量差异没有统计学意义(F=2.253,P＞0.05)；铁的含量试验组(饲喂葛根1周、2周、3周)高于对照组且差异有统计学意义(F=9.369,P＜0.05)；镁的含量试验组(饲喂葛根1周、2周、4周)高于对照组且差异有统计学意义(F=4.142,P＜0.05).生态葛根奶中铜、锌、钙含量与普通奶中含量无显著差异,铁、镁的含量较普通奶含量丰富.

| Abstract: | In order to determine the content of minerals and discuss the nutritive value of ecological Pueraria lobata Ohwi milk,the paper determined the content of copper,zinc,iron,calcium and magnesium in a milk sample of a test group(fed with Pueraria lobata Ohwi for four weeks) and in a control milk sample of a control group(produced by cows not fed with Pueraria lobata Ohwi) by flame atomic absorption spectrophotometry(FAAS) using HNO 3 and HClO 4 to digest the samples,and also analyzed the determination results ... |
