Decrease of phenolic content in canola meal using a polyphenol oxidase preparation from Trametes versicolor: effect of meal saccharification

摘要

A process to decrease the phenolic content of rapeseed meal using a polyphenol oxidase [catechol oxidase] preparation from T. versicolor [Coriolus versicolor] was carried out in the presence and absence of cell wall solubilizing enzymes. 85% of thepolysaccharide fraction of the cell wall of rapeseed meal was solubilized in the process. A complete decrease in phenolic content was observed in the presence of xylanase or cellulase preparations after 16 and 36 h of treatment, respectively. The initialrates of the process decreased by 10 and 5% in the presence of xylanase and cellulase preparations, respectively.
