英文摘要:

      Objective To optimize the process conditions for the extraction of natural vitamin E from blackberry by urea complexion method. Methods The natural vitamin E was extracted from the blackberry seed oil by urea complexion, and the optimal process parameters were determined by single factor test and orthogonal test. Results The optimum process parameters were mass ratio of urea to grease of 3?1, heating time of 30 min, heating temperature of 50 ℃, ethanol concentration of 95%, cold settling time of 4 h, and cold settling temperature of 0 ℃. The extract obtained under the conditions of the process had a vitamin E content of 3.21%. Conclusion This method can effectively extract vitamin E from blackberries.
