Abstract
Dehydrodivanillin, the symmetrical dimer of vanillin, is a taste enhancer which imparts pleasant impressions of creaminess to food. Found in vanilla pods in traces only, a co-substrate independent dimerization of vanillin, conducted in a co-solvent system to improve the solubility of vanillin, was developed using iso-active fungal laccases from Meripilus giganteus, Agaricus bisporus and Funalia trogii. The yields were compared with a peroxidase from Marasmius scorodonius (MsP2) and the reference enzyme horseradish peroxidase (HRP), both supplied with hydrogen peroxide. Using laccase catalysis, the kinetically preferred reaction product, 5,5'-dehydrodivanillin, rapidly reached saturation and precipitated in situ, thus shifting the reaction equilibrium to the product. Yields of>95 % were obtained with the high-redox-potential laccase of Funalia trogii, while HRP gave 18 %.
