Some nutritional properties of the peanut kernel and oils were established. The oil yields from these kernels vary from 32.7 % to 45.4 %. The content of protein ranged between 25.9 % to 32.4 %, with a mean value of 28.93 %. The mineral contents of peanut kernels were determined by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The contents of Na ranged from 867.7 mg/kg to 1186.1 mg/kg, with a mean value of 1004.7 mg/ kg. The phosphor contents of kernels ranged between 2769.7 mg/kg to 3784.9 mg/kg, with a mean value of 3433.91 mg/kg. The oil had a refractive Index (n 20) between 1.451 to 1.461 and a saponifiable value between 165.3 to 187.6. The main fatty acids in peanut kernel oils are oleic, linoleic and palmitic. Statistical differences between parameter to locatins were important at p < 0.05. As a result, the present study showed the peanut kernels of the researched species of Arachis kernels from Turkey to be a potential source of valuable oil which might be used for edible and other industrial applications.
确定了花生仁及花生油的一些营养特性。这些花生仁的出油率在32.7%至45.4%之间。蛋白质含量在25.9%至32.4%之间，平均值为28.93%。采用电感耦合等离子体原子发射光谱法（ICP-AES）测定了花生仁的矿物质含量。钠含量在867.7毫克/千克至1186.1毫克/千克之间，平均值为1004.7毫克/千克。花生仁中的磷含量在2769.7毫克/千克至3784.9毫克/千克之间，平均值为3433.91毫克/千克。该油的折射率（n20）在1.451至1.461之间，皂化值在165.3至187.6之间。花生仁油中的主要脂肪酸为油酸、亚油酸和棕榈酸。不同产地参数之间的统计差异在p<0.05时具有显著性。因此，本研究表明，来自土耳其的研究品种花生仁是一种有价值的油的潜在来源，可用于食用和其他工业应用。
