An experiment was carried out to characterize the proximate compositions and antinutritional and mineral contents of sorghum varieties released for production by the Ethiopian sorghum improvement programme. Sorghum is an extensively researched crop in Ethiopia. However, comprehensive information on nutritional, antinutritional, and mineral content has not been generated. In the present study, thirty-five sorghum varieties released by the national sorghum improvement programme were used and evaluated for their proximate compositions, tannin, and mineral nutrient. AOAC methods of analysis were used for proximate compositions and mineral content together, i.e., whereas for tannin, vanillin-HCL assay methods of analysis were used. Differences between sorghum varieties were significant ( ≤ 0.05) for all measured parameters. Proximate composition values such as moisture, ash, crude fat, crude fiber, crude protein, and CHO varied from 9.66 to 12.94, 1.12 to 2.29, 2.48 to 4.60, 2.17 to 8.59, 8.20 to 16.48, and 67.56 to 76.42, respectively. The highest mineral content of P (367.965), Na (6.151), Mg (207.526), K (314.011), Ca (67.159), Fe (14.018), and Zn (6.484) as measured by mg/100 g was found from the varieties Macia, Abshir, Chiro, Birmash, Dagem, and Assossa-1 (Fe and Zn), respectively. Maximum tannin values of 3337.200 and 2474.7 mg/100 g were obtained from Lalo and Dano, respectively. The varieties such as Miskir, Abshir, ESH-1, Meko-1, Red Swazi, and Karimtams have higher nutritional and mineral and lower antinutritional values among the tested varieties. The abovementioned varieties should be considered for food product development due to their nutritional qualities.
开展了一项实验，以表征埃塞俄比亚高粱改良计划发布的用于生产的高粱品种的近似成分、抗营养成分和矿物质含量。高粱是埃塞俄比亚一种经过广泛研究的作物。然而，尚未生成关于营养、抗营养和矿物质含量的全面信息。在本研究中，使用了国家高粱改良计划发布的35个高粱品种，并对其近似成分、单宁和矿物质营养进行了评估。近似成分和矿物质含量的分析采用美国官方分析化学师协会（AOAC）的方法，即对于单宁，采用香草醛 - 盐酸分析方法。所有测量参数在高粱品种之间的差异均具有显著性（≤0.05）。近似成分值，如水分、灰分、粗脂肪、粗纤维、粗蛋白和碳水化合物，分别在9.66至12.94、1.12至2.29、2.48至4.60、2.17至8.59、8.20至16.48以及67.56至76.42之间变化。按毫克/100克测量，磷（367.965）、钠（6.151）、镁（207.526）、钾（314.011）、钙（67.159）、铁（14.018）和锌（6.484）的最高矿物质含量分别在品种马西亚、阿卜希尔、奇罗、比尔马什、达格姆和阿索萨 - 1（铁和锌）中发现。分别从拉洛和达诺获得的最大单宁值为3337.200和2474.7毫克/100克。在测试品种中，米斯基尔、阿卜希尔、ESH - 1、梅科 - 1、红斯威士和卡里姆塔姆斯等品种具有较高的营养和矿物质含量以及较低的抗营养值。由于其营养品质，上述品种应被考虑用于食品开发。
