Development and industrial application of geographical origin identification for Taiwanese oolong tea.

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.

Photodynamic and Antibacterial Assessment of Gold Nanoparticles Mediated by Gold (III) Chloride Trihydrate and Sodium Citrate under Alkaline Conditions.

Sodium citrate (SC) is sensitive to violet light illumination (VLI) and acts as a weak reductant. Conversely, gold (III) chloride trihydrate (GC) often acts as an oxidant in a redox reaction. In this study, the influences of colored light on the production of gold nanoparticles (AuNPs) in a mixture of gold (III) ions and citrate via VLI and the antibacterial photodynamic inactivation (aPDI) of () are determined under alkaline conditions.

SSR-based molecular diagnosis for Taiwan tea cultivars and its application in identifying cultivar composition of the processed tea.

Taiwan specialty teas are produced with distinct manufacturing processes from specific cultivars of tea plants in Camellia. Due to the widespread transplantation of Taiwan tea cultivars and active international trading of tea materials, an accurate and reliable method to identify tea cultivars at the border is vital to protect the image of premium Taiwan specialty teas. In this study, we introduced the Taiwan Tea Variety Identification (TTVID) kit, a capillary electrophoresis-based multiplex PCR assay consisting of 12 simple sequence repeat (SSR) markers.
