title: Some nutritional characteristics of kernel and oil of peanut (Arachis hypogaea L.).
abstract: 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.
