Multivariate Analysis for the Classification Differentiation of Brazilian Sugarcane Spirits by Analysis of Organic and Inorganic Compounds

Abstract

Brazilian sugarcane spirits were analyzed to elucidate similarities and dissimilarities by principal component analysis. Nine aldehydes, six alcohols, and six metal cations were identified and quantified. Isobutanol (LD 202.9 µg L⁻¹), butiraldehyde (0.08–0.5 µg L⁻¹), ethanol (39–47% v/v), and copper (371–6068 µg L⁻¹) showed marked similarities, but the concentration levels of n-butanol (1.6–7.3 µg L⁻¹), sec-butanol (LD 89 µg L⁻¹), formaldehyde (0.1–0.74 µg L⁻¹), valeraldehyde (0.04–0.31 µg L⁻¹), iron (8.6–139.1 µg L⁻¹), and magnesium (LD 1149 µg L⁻¹) exhibited differences from samples.
