Synthetic dyes typically contain impurities formed during the manufacturing process, including intermediates, by-products and colored impurities called as subsidiary colors. Among synthetic dyes, azo dyes were synthesized similarly by diazotization and coupling reactions, which can produce similar subsidiary colors. Since azo dyes and their subsidiary colors are known to possess carcinogenic and other toxic properties, appropriate control measures need to be required. In this study, we developed an analytical method for the simultaneous determination of 10 subsidiary colors derived from azo dyes using high performance chromatography-diode array detector (HPLC-DAD), and monitored subsidiary colors and Food Yellow No. 5 (sunset yellow FCF) in commercially available raw materials and beverages. The developed method can successfully detect subsidiary colors at low level of 0.012―0.068 mg/L, and show acceptable performances for accuracy and precision. As percentage contents of subsidiary colors in commercial beverages containing Food Yellow No. 5 were lower than or comparable to those in raw materials, most of subsidiary colors were not intentionally added to beverages but are presumed to be produced from Food Yellow No. 5. We also found that the percentage contents of subsidiary colors in commercial food colorants satisfied the national and international ‘Specifications and Standards for Food Additives’.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
