Gallocatechin gallate-containing composition

The present invention provides a safe and highly effective antibacterial composition without impairing the flavor of foods or drinks, which composition is used in products such as foods and oral care goods which are mainly to be taken into human or animal bodies or mainly to be used in the oral cavity. The composition according to the present invention contains gallocatechin gallate as an agent for enhancing the activity of antibacterial catechins in which the antibacterial activity of the antibacterial catechins against Streptococcus mutans is particularly enhanced. The composition according to the present invention can be produced by mixing the antibacterial catechins with gallocatechin gallate. Alternatively, it can be produced as a composition comprising a synthetic adsorbent-adsorbed fraction as the main component, which is obtained by subjecting a solvent-extract from tea leaves to an adsorption treatment with the use of a synthetic adsorbent selected from among aromatic compound-based synthetic adsorbents and methacrylic compound-based synthetic adsorbents.

Preparation method and process for antibacterial modification of ceramic whiskers

The invention relates to a preparation method and process for antibacterial modification of ceramic whiskers and in particular provides a preparation method for fusion-coating of zinc oxide nanoparticles having different patterns on the surface of hydroxyapatite whiskers. The preparation method is characterized by adding dropwise an ethanol solution of a zinc salt into a beaker in which an ethanol solution of hydroxyapatite whiskers is held, performing stirring, rotating, ultrasonic treatment, drying and calcination procedures to make zinc oxide-hydroxyapatite whiskers. The ceramic whiskers have antibacterial effects. The zinc oxide nanoparticles have good antibacterial effects and the antibacterial rate against Streptococcus mutans reaches (93.58 plus or minus 5.95) percent; and the hydroxyapatite whiskers have high strength. After modification, zinc oxide nanoparticles, nanospheres, nanorods, microspheres and diamond-shape units are uniformly distributed on the surface of the hydroxyapatite whiskers by fusion coating, the particle size is 30 nm to 400 nm, the surface area and the roughness are greatly improved, and the mechanical embedment force between the zinc oxide nanoparticle and the matrix is increased. Therefore, the zinc oxide-modified hydroxyapatite whisker can serve as an ideal reinforcing material with antibacterial effect.
