Objective: To establish odor fingerprint by electronic nose technology and distinguish different processed products of Alpiniae Oxyphyllae Fructus. Method: Crude
stir-frying with water and salt products of Alpiniae Oxyphyllae Fructus were detected by electronic nose technology
then response values were obtained by the sensors
data was analyzed by chemometrics methods
such as principal component analysis
discriminant factor analysis
statistical quality control analysis. Result: The crude
stir-frying with water and salt products could be distinguished from each other obviously through chemometrics analysis.Odor of the crude was quite different from its processed products
odor of stir-frying with water and salt products was similar. Conclusion: Electronic nose technology can be used for distinguishing processed products of Alpiniae Oxyphyllae Fructus
this study indicate that odor changes of Alpiniae Oxyphyllae Fructus mainly caused by heating up.
