“…Infrared (IR) spectroscopy, as a detection technology, has some advantages such as rapid, convenience, high efficiency, nondestructive, and low cost (Pereira, Leite, Andrade, Bell, & Anjos, 2019; Sun et al., 2017; Yang, Li, Song, Gao, & Zhou, 2018). IR spectroscopy technology has been widely applied in many fields such as food inspection (Jiang & Chen, 2015; Liu et al., 2019; Sun, Ge, Wu, Dai, & Yang, 2018; Tahir et al., 2017), classification of agricultural products (Chen, Lin, & Tan, 2019; Ferreiro‐González et al., 2018; Wu, Wu, Sun, & Yang, 2017; Wu, Yang, & Wang, 2018), and pharmaceutical analysis(Mazivila, Castro, Leitão, & Esteves da Silva, 2019; Oparin & Kiselev, 2020).…”
