Distinguishing Korean and Chinese red pepper powder using inductively coupled plasma and X-ray fluorescence-based analysis

다국어 초록 (Multilingual Abstract)

This study aimed to distinguish between Koreanand Chinese red pepper powder (RPP) using inorganicelemental analysis data combined with orthogonal partialleast squares-discriminant analysis (OPLS-DA). Elementalconcentrations were obtained for 31 Korean and 31 ChineseRPP samples that were collected in Korea. Energydispersive X-ray fluorescence spectroscopy detected 11elements in these samples. Rb and Cl concentrations wereselected as the variables which best allowed distinguishingbetween Korean and Chinese RPP using an S-plot fromOPLS-DA. Rb and Cl concentrations in the Korean RPPsamples were B 1.6 mg/100 g (measured by inductivelycoupled plasma-optical emission spectroscopy) andB 215 mg/100 g, respectively. A blind trial demonstratedthat Korean RPP containing C 50 g/100 g of Chinese RPPcould be identified by applying predetermined ranges of Rband Cl concentrations, suggesting that analysis of these twoelements is a possible approach to distinguish betweenKorean and Chinese RPP.
