Effectiveness of the solvents for oil extraction from the prepared for direct extraction sunflower seed kernels
The article discusses the results of evaluation of solvents used for oil extraction from sunflower seed kernels prepared for direct extraction. The effectiveness of traditional hydrocarbon solvent Nefras P 63/75 which is used at oil mills for oil extraction from sunflower cake is compared with alcohol class extractants, namely, ethanol and isopropanol. Comparative efficacy of extractants action was evaluated on the basis of extraction kinetic curves obtained on the computerized research complex under various experimental conditions. The order of solvents efficacy was determined as follows: Nefras, isopropanol, ethanol.
