The aim of this study was to analyze the relationship between oolong tea drinking and bone mineral density in postmenopausal Han Chinese women, while living and diet habits, fertility, disease elements and other baseline conditions were controlled. One group included 124 cases who routinely drank oolong tea, and the other included 556 who did not drink tea. Data were collected on participant age, lifestyle habits, fertility condition, disease elements, and lumbar, and hip bone densities. It was found that the bone densities of the greater trochanteric bone in tea drinkers were higher (0.793 ± 0.119 kg/cm(2)) than that in non-tea drinkers (0.759 ± 0.116 kg/cm(2), F = 6.248, p = 0.013). Similarly, the bone density of Ward's triangular bone in tea drinkers was higher (0.668 ± 0.133 kg/cm(2)) than that in non-tea drinkers (0.637 ± 0.135 kg/cm(2), F = 6.152, p = 0.013). Oolong tea drinking could help prevent bone loss in postmenopausal Chinese women.

Taiwanese oolong tea is renowned for its excellent quality and enjoys a prestigious reputation both domestically and internationally. In recent years, there has been an issue with imported Taiwanese-style oolong tea being sold as genuine Taiwanese oolong tea, which has adversely affected the brand value of Taiwanese oolong tea. In this study, samples of domestic oolong tea (Taiwanese oolong tea) and Taiwanese-style oolong tea produced abroad (including China, Vietnam, Indonesia, Thailand, etc.

Purpose: Ionizing radiation (IR) could induce damage such as DNA damage and oxidative stress. Natural products, like tea, have been demonstrated potential in mitigating these damages. However, the lack of efficient and rapid screening methods for natural products hinders their widespread application.

The levels of flavor compounds and hazardous compounds are important indicators for evaluating high-temperature roasted food. In this paper, the effect of tea pre-marination on non-volatile compounds, volatile compounds, and hazardous compounds in roasted chicken. The results showed that the total content of key umami non-volatile compounds in roasted chicken marinated with green tea, white tea, and black tea increased by 17.
