Abstract

Abstract:

Seventy-six liquor samples including 49 brands of Luzhou-flavor liquor, 7 brands of Maotai-flavor liquor, 10 brands of Fen-flavor liquor, 6 brands of rice-flavor liquor and 3 brands of Dong-flavor liquor were analyzed for physicochemical properties to evaluate the correlations between them and aroma quality assessed by 10 professional sommeliers. Total acid content exhibited a positive correlation with aroma intensity or harmony and the correlation was the strongest among the 5 physicochemical parameters tested. Some chemical parameters like total acid and total ester contents made a big difference to the aroma quality of liquor. Little effects of some physical parameters like Brix, electrical conductivity and viscosity on the aroma quality of liquor were observed.

Key words: liquor, physico-chemical properties, aroma quality, correlation analysis
