COLORIMETRIC METHOD FOR DETERMINING THE COLOR OF WINE FROM THE GRAPE

摘要

The invention relates to a method for determining the colour of wine from grapes. The method involves digesting the grapes in a pectolytic enzyme solution and a sulfur dioxide solution; diluting the solution with diluted acid and spectrophometric reading of the resulting solutions. The invention also relates to a program that calculates the probable colour of the wine based on the spectroscopic data and physical-chemical parameters of the wine.
