Optimization of Bran-roasted Processing Technology of Chebulae Fructus by Orthogonal Design
Objective: To optimize bran-roasted processing technology of Chebulae Fructus. Method: With composite score of appearance and the content of free gallic acid as index
orthogonal design was adopted to optimize processing technology by taking bran amount
processing time and temperature as factors.HPLC was empolyed to determined the content of gallic acid with mobile phase of acetonitrile-0.1% formic acid(3:97) and detection wavelength at 273 nm. Result: Optimal processing technology was as follows:roasted 20 min with 0.4 times the amount of bran at (140±5) ℃;the content of gallic acid was up to 27.62 mg·g-1. Conclusion: Optimized processing technology was stable and feasible
which could provide process parameters for industrial production and quality control of Chebulae Fructus.
