Pomegranate composite healthcare fruit vinegar and making method thereof

The invention discloses pomegranate composite healthcare fruit vinegar and a making method thereof. By adopting the method, pomegranate juice is subjected to three times of fermentation treatment, andthrough control on conditions of three times of fermentation and adjustment on substrate components and concentrations, not only is generation of ethanol, acetic acid and flavone substances remarkably increased, but also decomposition of phenolic substances can be reduced in the pomegranate juice fermentation process, so that contents of the ethanol, acetic acid and flavone substances in the madepomegranate fruit vinegar can be high, furthermore, a good healthcare effect can be achieved, and large-scale production and popularization of the pomegranate composite healthcare fruit vinegar can be benefited. 本发明公开了一种石榴复合保健果醋及其制备方法，该方法对石榴汁进行了三次发酵处理，利用对三次发酵条件的控制以及对底物成分和浓度的调整，使石榴汁在发酵过程中，不仅能显著增加乙醇、醋酸以及黄酮类物质的生成，还能减少酚类物质的分解，从而使制备得到的石榴果醋中的醋酸、酚类和黄酮类物质含量更高，进而具有更好的保健效果，有利于石榴复合保健果醋的大规模生产和推广。
