Abstract

Vine tea extract (VTE), from the traditional Chinese herbal tea, was added to reconstituted skimmed milk; the mixture was fermented with , and fermentation characteristics, flavonoid content, antioxidant capacity (AOC), and viability of were measured. 2 mg/mL VTE promoted growth and 8 mg/mL VTE inhibited growth, an effect consistent with observed pH changes. Total flavonoid content and AOC increased with increasing VTE dosage. Dihydromyricetin was partially metabolized during fermentation and accounted for most of the antioxidant function of VTE. 2 mg/mL VTE was optimal for maintenance of probiotic culture and pH stability during cold storage and improved AOC during product shelf life. VTE has the potential to increase the health benefits of probiotic dairy products, and the resulting mixture may be suitable to use as a daily milk-based health drink.
