Title
(EN) ENZYMATIC COMPOSITION FOR REFINING WOOD
(FR) COMPOSITION ENZYMATIQUE ET PROCEDE POUR L'AFFINAGE DU BOIS
Abstract
(EN)
The invention relates to an enzymatic composition and to a method for refining wood, especially for applications in the food industry. The inventive method consists in immersing green lumber in an aqueous solution that includes an enzymatic composition. The wood can subsequently be dried very quickly in a drying facility. The invention enables the aromatic characteristics of wood to be improved by eliminating certain substances that are considered to undesirable on account of their astringent or bitter character by transforming them into neutral-tasting molecules.
(FR)
L'invention concerne une composition enzymatique ainsi qu'un procédé d'affinage du bois, destiné notamment à des applications alimentaires. Le procédé consiste à immerger du bois vert dans une solution aqueuse comportant une composition enzymatique. Par la suite, le bois peut être séché de façon très rapide au séchoir. L'invention permet d'améliorer les caractéristiques aromatiques des bois en éliminant certaines substances jugées indésirables de par leur caractère astringent ou amer et en les transformant en molécules gustativement neutres.
