Embodiment 1
[0025] In the test, Yunzhi extracts came from different origins (Northeast, Longquan, Changbai Mountains, Dabie Mountains in Anhui, and Daxing’an Mountains), and the dextrin used for adulteration came from Henan (Henan Datian Food Additive Co., Ltd.), a total of 140 samples. Using the method of intuitive classification, all samples are divided into modeling set and verification set according to the ratio of 4:1, as shown in Table 1.
