Objective:This subject aimed to establish a rapid detection method about sulfur fumigated Pinellia Tuber. Methods:According to change of the smell between Pinellia Tuber and sulfur fumigated Pinellia Tuber, use a electronic nose to detect them and establish a model to detect and analyze unknown samples. Then optimize and calibrate the model. Scanning the Near Infrared Spectroscopy is based on the determination of the content variation of succinic acid, alkaloids, amino acid,etc. Establish a Near Infrared mo...
