Therefore, microorganisms play an extremely important role in the flavor, texture and activity of fermented foods. Moreover, fermentation promotes complex flavor components, and the compounds jointly influence the physicochemical properties and the physiological activity of the fermented substances.
The Zygosaccharomyces rouxii (Zygosaccharomyces rouxii) belongs to the genus Zygosaccharomyces, Saccharomyces, Zygosaccharomyces, phylogenetically, in the kingdom of eukaryotes. The colony is round, glossy, flat and neat in edge. The zygosaccharomyces rouxii is a common high-permeability-resistant yeast, and is mainly used for producing products such as soy sauce, sweet sauce, flavor enhancer and the like by fermentation traditionally. In the industrial production, the arabitol sugar can be produced by fermentation. In the field of food technology, Saccharomyces rouxii (Zygosaccharomyces rouxii) can also be used for culturing and adsorbing heavy metal cadmium. However, the application in functional foods and functional cosmetics is hardly reported.
Polyphenols and flavonoids are widely present in plants, are natural antioxidants, and are capable of scavenging active oxygen and free radicals in the body and preventing oxidative stress effects. The polyphenol and the flavonoid compound contain polyhydroxy structures and can be chelated with metal ions to form a complex, so that the polyphenol and the flavonoid compound not only can inhibit aging and related diseases caused by lipid oxidation and the like caused by metals, but also can chelate copper ions at the active part of tyrosinase to form tyrosinase activity inhibition, and in recent years, the polyphenol and the flavonoid compound are valued by the cosmetic industry and have important prospects in the research and development of functional foods and cosmetics.
According to the invention, by carrying out microbial separation on the traditional rose sugar in the Dali white region, a strain of Saccharomyces rouxii (Zygosaccharomyces rouxii) is separated and identified and added into the rose liquid for fermentation, the total polyphenol and total flavone contents of the rose liquid after fermentation are obviously improved, and the antioxidant activity and tyrosinase inhibitory activity of the rose liquid are increased.
