Fecha de publicación: -- Fuente: WIPO "wine" The invention relates to wine industry, namely to methods for estimation of efficiency of enzyme preparation action and determination of direction of their use in wine production. A method consists in the selection and determination at the most important technological stages of wine production of physical-chemical, technological and organoleptic test indices and wine material in control samples and samples, which were treated with enzyme preparation followed by mathematical processing and comparative data analysis. The method will allow to assess with high probability the efficiency of action and direction of use of enzyme preparation in the process of production of wine materials of various types (white and red table, strong and dessert), which finally will improve wine quality.
