摘要: 为全面了解新疆芜菁的食用价值,选取了新疆芜菁主产区的13个芜菁品种,对其营养成分进行分析评价,为充分开发与利用新疆芜菁资源,提高新疆芜菁产品的附加值提供依据。本实验运用高效液相色谱法(High Performance Liquid Chromatography,HPLC)、原子吸收分光光度法(Atomic Absorption Spectrophotometer,AAS)测定了13种新疆芜菁中所含氨基酸、蛋白质、钙、镁等矿质元素含量。结果表明:在参试品种中,绿昆芜菁的总氨基酸含量、蛋白质、总矿物质含量均最高,分别为12.32%、2.33%、57488 mg/kg。结论:绿昆芜菁具有高氨基酸、高矿质元素、高蛋白、低酸等优良品质,适宜作为优质栽培品种,其次为柯坪芜菁和亚华芜菁。不同品种新疆芜菁营养成分含量较高,蛋白质及矿物质元素含量丰富,营养价值高,具有良好的食用价值和开发前景。Abstract: To fully understand edible value of Xinjiang turnip,13 species of Xinjiang producing area were selected to examine the nutrient composition. This research provided basis for the development and utilization of Xinjiang turnip resources and could enhance the added value. The content of amino acid,crude protein,Ca,Mg,and other mineral elements of 13 Xinjiang turnip species were detected by high performance liquid chromatography(HPLC) and atomic absorption spectrophotometer(AAS). The results showed that Lukun turnip with the highest levels contents of amino acid(12.32%),protein(2.33%) and mineral element(57488 mg/kg). By comparing nutrient composition of 13 Xinjiang turnip species,Lukun turnip was the best,followed by Keping turnip and Yahua turnip. Xinjiang turnips with high nutritional value,rich in amino acid,protein and mineral elements,had high edible value and great development prospects.
