Research progress on bioactive components and functions of traditional vinegar concentrates
The vinegar business is an important component of biotechnology industry in China.Vinegar concentrates,which can be naturally formed through the traditional vinegar aging process or produced through other methods like concentration,drying,can exist in various forms,including vinegar sediment and vinegar powder.In this review,we first described the active components in vinegar concentrates,including organic acids,polysaccharides,proteins,flavonoids,polyphenols,and ligustilide.Then,we systematically summarized the latest research on their functions,encompassing antioxidant,anti-inflammatory,lipid-regulating,hepatoprotective,and gut microbiota-modulating properties.This review will not only provide a theoretical foundation for optimizing vinegar fermentation processes,but also offer a scientific basis for the development of novel functional vinegar products,potentially guiding targeted nutrition design and precision manufacturing in food industry.
