Abstract:The extraction technology of red pigment from beet was optimized by ultrasonic assisted ethanol extraction. On the basis of single factor experiment, orthogonal experiment to optimize the extraction of beet red pigment process, determine the best extraction conditions as follows: ethanol concentration was 40%, the leaching solution pH value of 5.5, and solid-liquid ratio of 1∶10, 90% W ultrasonic power, extraction temperature 40 ℃, the extracting time for 40 min.
Keywords:betacyanin; process optimization; orthogonal experiment; ultrasonic extraction
