Discrimination and prediction of the origin of Chinese and Korean soybeans using Fourier transform infrared spectrometry (FT-IR) with multivariate statistical analysis

Abstract: The ability to determine the origin of soybeans is an important issue following the inclusion of this information in the labeling of agricultural food products becoming mandatory in South Korea in 2017. This study was carried out to construct a prediction model for discriminating Chinese and Korean soybeans using Fourier-transform infrared (FT-IR) spectroscopy and multivariate statistical analysis. The optimal prediction models for discriminating soybean samples were obtained by selecting appropriate scaling m… Show more

“…Thus, the IR spectra can be used to identify or differentiate between samples [14]. The list of applications includes evaluating and determining components [15,16], monitoring contaminants and adulterants [17,18], classification [19,20], discrimination [21,22], authentication [23,24], etc. In this context, the review of Rodriguez-Saona and Allendorf [25] is worth mentioning.…”

“…CCD, a type of RSM technique introduced by Box and Wilson (1951), was composed of three parts, including full factorial or fractional factorial design, star points, and center point (Box and Wilson, 1951). This design was successfully generated and applied for optimizing isoflavones extraction of soybean of DT2010 (Le et al, 2019), BRS 257 (Yoshiara et al, 2018 and JS 335 cultivar (Lakshmi et al, 2013). Several optimization parameters, namely, solvent concentration, extraction time, reaction temperature, solvent-material ratio, and pH, can be defined as experimental factors to achieve optimized extraction conditions.…”
