| Abstract: | In this study,we extracted the protein of sunflower kernel with salt extraction,took the extraction rate as an evaluation index,discussed the influence of NaCl concentration,solid-liquid ratio,extracting temperature,extracting time,pH value and extraction times on the extraction rate of protein,and optimized the extraction process using orthogonal test.The results indicated that the optimum extraction conditions of protein in sunflower kernel are: NaCl concentration 1.5mol·L-1,solid-liquid ratio 1:14(g·mL-1),extracting temperature 50℃,extracting time 1.5h,pH value 8,extraction times 2.The extraction rate of protein is 54.8% under these conditions. |
