| Abstract: | Organic solvent method was employed to extract carotenoids from carrot powder.Through the single factor experiment,extraction temperature,time and the ratio of liquid to carrot powder respectively on the yield of carotenoids were screened.Orthogonal test indicated under the temperature at 60 ℃ and 8 h of extraction the optimum ratios of acetone to methanol(V/V) and solid to liquid(W/V) were 2∶1 and 1∶15 respectively.Under these conditions,the yield of carotenoids from carrot powder could reach 89.82 mg/100 g. |
