However, since this type of beverage or the like has a flavor odor, the flavor odor adheres firmly to manufacturing equipment, particularly packing, and the like, and deodorization of the flavor odor is a major problem.

  As a flavor odor deodorization technique, conventionally, a method of repeatedly performing deodorization and washing using an acidic or alkaline detergent, or the above-mentioned repeated deodorization and washing, followed by oxidation of sodium hypochlorite, peracetic acid, percarbonate, etc. A method of performing a deodorizing treatment by bringing the agent, tea extract or the like into circulation contact is adopted. However, even if such washing or deodorizing treatment is performed, a sufficient deodorizing effect is not seen.

Furthermore, a deodorant composition for CIP cleaning containing a specified nonionic surfactant such as polyoxyalkylene fatty acid ester as a main component is also known (Japanese Patent Laid-Open No. 2003-49193). This composition is less damaging to the production equipment, has low foam and has a deodorizing performance, but has a weak deodorizing effect.
