Özet

Vinegar is a widely used condiment in the world, and is produced from ethanol by acetic acid fermentation. Different fruits, vegetables, cereals, and wines can be used as ingredients for vinegar production. It is known that vinegar has many nutrient components such as organic acids, polyphenols, and aromatic compounds. Because of these bioactive components, it has many health benefits. China has a long history of producing vinegar and has been using it for health products and as medicine. Chinese aromatic Zhenjiang vinegar (Kozu) is produced from sticky rice. It is famous for its special flavor and health benefits. 5-Hydroxy-4-phenyl-butenolide (Fraglide-1) is a functional compound discovered in Kozu and has anti fungal and anti-obesity effects. In this study, the Fraglide-1 content of different kinds of vinegars and ingredients, including Kozu samples and ingredients, was investigated. Fraglide-1 analysis was carried out via LC-MS/MS in multiple reaction monitoring mode. It was found that all the Kozu samples, as well as brown rice vinegar (Kurosu) samples, and the Chinese sticky rice husk used for the production of Kozu, contained Fraglide-1. Kozu production requires a 6-month- to 8-year-long aging process for its special flavor and aroma. Because of this long aging process, Fraglide-1 is thought to move from the sticky rice husk to Kozu.
