Objective: To elucidate the processing mechanisms of Corni Fructus from the viewpoint of Maillard reaction. Method: Corni Fructus was processed in several different methods and the changes of physicochemical parameters in reaction system were analyzed. pH values were measured in different time points in processing to show acid-base variables. Determination of browning degree was carried out by UV spectrophotometry. The content changes of 5-HMF
one of the products of Maillard reaction
was determined by HPLC. Result: The 12 h before Corni Fructus processing
the pH values were decreased
A284 and A420 values were increased and contents of 5-HMF were increased significantly. All the changes slowed down and became stable after 24 h. Conclusion: Study on processing of Corni Fructus from the viewpoint of Maillard reaction could not only reveal the mechanism of processing from a new perspective
but also provide the scientific basis for the optimization of processing technology.
