Title: Optimization of Ultrasonic-assisted Extraction Parameters of Maize Yellow Pigment from Corn
Abstract: The maize yellow pigment was extracted from corn barn through ultrasonic-assisted extraction technology using ethanol as an extracting agent. The effects of parameters such as material-to-liquid ratio,volume fraction of ethanol, extracting temperature and time on the extraction rate of yellow pigment were investigated. The results showed that the extraction rate was up to 6.274% under the optimum extraction condition, e.g. volume percentage of ethanol 60%, corn barn to ethanol ratio of 1∶15, extraction temperature 50 ℃ and extraction time of 30 min.
