Abstract:Preparation of a novel functional solid tea product is described in this study.The tea was pretreated by utral-fine grinding technology.Under optimal process conditions,contents of flavonoids and polyphenols in Eight-treasure tea were increased by 2.27 and 1.65 times.The DPPH radical scavenging ability was increased by 1.35 times.ABTS+radical scavenging ability was increased to 77.77%.The ferric ion reduction antioxidant power was 1.41 times that of samples with no ultra-fine grinding.Mannitol,lactose,and xanthan gum were added for improving stability,flavor,and dispersion capability in water,respectively.The Eight-treasure tea solid beverage inhibited the generation of tyrosinase and melanin,displayed antioxidant capacity,and inhibited pigmentation capacity.The tea is rich in biologically active compounds and has good flavor.
