| 摘要 |
This invention provides a highly concentrated licorice polyphenol preparation with high bioavailability. Further, this invention is intended to maintain high transparency of a composition without deterioration of the indigenous properties of an aqueous substance, even when such composition is added thereto. Such licorice polyphenol preparation comprises a hydrophobic licorice extract comprising licorice polyphenol as a primary component, medium-chain fatty acid triglyceride, and polyoxyethylene sorbitan fatty acid ester, and the ratio of the total weight of the hydrophobic licorice extract and medium-chain fatty acid triglyceride to the weight of polyoxyethylene sorbitan fatty acid ester is between 1:1 and 1:10.
