The present invention provides an effective method of removing off-flavor from foods such as seafood, meat products and vegetables, which comprises causing a polymer of phenol compounds having a styrene structure and/or a reaction mixture produced by conducting an oxidation reaction of the phenol compounds having a styrene structure in the presence of oxygen to be present in the food. Also provided is a deodorizer comprising a polymer of phenol compounds having a styrene structure.

A new method for the preparation of substituted dihydrobenzofurans is described. The p-alkenylphenols, mediated by cerium ammonium nitrate (CAN), undergo the oxidative dimerization to generate substituted dihydrobenzofurans including (+/-)-conocarpan, (+/-)-licarin A, (+/-)-acuminatin, as well as their related substituted dihydrobenzofurans.

Synthesis of Enantiomerically Enriched Dimers of Vinylphenols by Tandem Action of Laccases and Lipases
The tandem use of laccases and lipases has been exploited for the simple preparative synthesis of enantiomerically enriched dimeric phenols. Laccase‐catalyzed oxidation of isoeugenol (1) and vinylguaiacol (7) in biphasic systems gave as main products the racemic compounds 6 and 8, possessing structures similar to the β‐5 dimers found in lignin. The synthesis of enantiomerically enriched 6 and 8 could
