Objective: To study oncontent variation of 5-hydroxymethylfurfural(5-HMF) in bran-frying process of Atractylodis Macrocephalae Rhizoma
and investigate its correlation with temperature and color changes of decoction pieces. Method: Atractylodis Macrocephalae Rhizoma was fried with stir-frying machine
and sampled at different time points.HPLC was applied to determine the content of 5-HMF with mobile phase of methanol-water (5:95) and detection wavelength at 284 nm.Two-dimensional infrared imager was adopted to measure the temperature of decoction pieces at different time points;color difference meter was empolyed to measure the color of decoction pieces at different time points. Result: 5-HMF in raw products of Atractylodis Macrocephalae Rhizoma was not detected.As bran-frying time extended
5-HMF content increased slowly
when stir-frying about 15 min and temperature of decoction pieces at 150℃
5-HMF content sudden rise sharply
and at this time
the color b* values of decoction pieces entered a significant decline phase. Conclusion: The content of 5-HMF changes regularly in the bran-frying process of Atractylodis Macrocephalae Rhizoma
and it has a remarkable correlation with temperature and color changes of decoction pieces.
