Method and device for objective qualitative analysis of grape must and/or wines using wideband infrared spectrometry

摘要

A method and a device for objective qualitative analysis of liquid winemaking compositions, includes storage means (8) wherein are recorded calibrating values of spectroscopic criteria for a group of characteristic parameters comprising concentration levels of at least a compound formed by Botrytis cinerea, at least a compound formed by yeasts, at least a compound formed by acetic bacteria, and at least a compound formed by lactic acid bacteria, means (1, 2, 3, 4, 6) for producing a continuous infrared spectrum, and means for calculating the value Vp of each characteristic parameter in the composition from the spectrum.
