Title: Study on the Extraction Technology of Grape Seed Oil by Solvent Method
Abstract: [Objective] The research aimed to provide the experimental basis for the production,development and utilization of grape seed oil.[Method] Grape seed oil was extracted by using solvent method.The effects of extraction time,material-liquid ratio,extraction temperature on the extraction ratio of grape seed oil were studied through single factor test.The optimum extraction technology of grape seed oil was confirmed through orthogonal test.[Result] When petroleum ether was taken as petroleum ether,the extraction ratio of grape seed oil was highest.The extraction ratio was increased with the increasing of extraction time.The increasing trend of the extraction ratio was not obvious after 3 h.When the material-liquid ratio was 1∶8,the extraction ratio reached the maximum. The extraction ratio of grape seed oil was increase gradually long with the rising of extraction temperature and the increasing amplitude was greater at 50-60 ℃.The effects of each factor on the extraction ratio of grape seed oil in order was as follows: extraction timeextraction temperaturematerial-liquid ratio.[Conclusion] When petroleum ether was taken as petroleum ether,the optimum extraction technology of grape seed oil was as follows: extracting with the material-liquid ratio of 1∶8 at 70 ℃ for 5 h.Under these conditions,the extraction ratio of grape seed oil was 14.85%.
