초록

Red pepper powder is a necessary ingredient in our culinary culture, using in a variety of dishes such as Kimchiand salted seafood. As the global food landscape expands, the kind of red pepper powder is diversified, leading to anincreased consumption trend. FTA was implemented in 2010 and almost agricultural products expected to be fully opened tointernational trade by the early 2030s. Red pepper powder imported with a low tariff has the potential to trigger aself-sufficiency collapse in the domestic red pepper industry and leading to a fraud of red pepper powder(ex. mislabeling). Inresponse, this study seeks to develop a testing method for discerning the origin of domestic and imported red pepper powderand furthermore aims to mitigate social and economic confusion caused by inaccurate information provision and unjustifiableexpenses. This study secured each 60 samples of red pepper powder from domestic and Chinese origin and then acomprehensive literature review guided the selection of components for analysis. Instrumental analyses, involving equipmentsuch as HPLC, UV spectroscopy, ICP, IR-MS, were conducted through necessary pre-treatment. Among the 28 componentsanalyzed, significant differences were observed in fructose, ASTA color value, total polyphenol content, Al, Fe, Na content andnitrogen isotope ratio mass analysis. Leveraging these findings, statistical techniques like discriminant analysis and logisticregression analysis were applied, yielding classification accuracies of 91.7 % and 98.3 %, respectively.
