This study examined the volatile organic compounds (VOCs) and metabolites of glucosinolate (GLS) contained in kimchi and analyzed GLS using myrosinase. The analysis was conducted using gas chromatography-time of flight (GC-TOF), and VOC and the metabolite quantities were detected and analyzed. Based on 22 samples, tests were conducted, and 12 metabolites and 52 VOCs were found. When the detected metabolites were compared in general, the rate of isothiocyanate, which is well known for its anticancer effects and various other activities, was the highest. A total of 52 VOCs, including 15 aliphatic hydrocarbons, 7 acids, and 6 alcohols, were detected by GC-TOF. Therefore, the analytical methods provide a good basis to examine VOC and GLS metabolites; furthermore, the methods are of great help to secure excellent kimchi and evaluate its quality.

开发用于检测泡菜中硫代葡萄糖苷代谢物和挥发性有机化合物的气相色谱-飞行时间法

本研究检测了泡菜中所含的硫代葡萄糖苷 (GLS) 的挥发性有机化合物 (VOC) 和代谢物，并使用黑芥子酶分析了 GLS。使用气相色谱-飞行时间 (GC-TOF) 进行分析，并检测和分析 VOC 和代谢物数量。对22个样品进行检测，发现12种代谢物和52种VOCs。当对检测到的代谢物进行总体比较时，异硫氰酸酯的比率最高，异硫氰酸酯以其抗癌作用和其他各种活性而闻名。GC-TOF 共检测到 52 种 VOC，包括 15 种脂肪烃、7 种酸和 6 种醇。因此，该分析方法为检测 VOC 和 GLS 代谢物提供了良好的基础；此外，这些方法对确保优质泡菜和评估其质量有很大帮助。
