Abstract
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.
