METHOD FOR DETERMINING QUALITY OF ROSE AND RED WINES AS NATURAL PRODUCTS

摘要

The proposed method for determining quality of rose and red wines as natural products consists in selecting the wine sample, applying the sample to filtering paper, and examining how the color of the sample would be changed. Before applying the probe, the filtering paper must be impregnated with sodium or potassium carbonate solution, with the concentration of dry substance 8 ... 12 % by weight, and then dried.
