The effect of methyl cellulose as a thickening agent for beverages on the rating of sensory viscosity was pronounced. Acidity ratings depended on the assessors as their sensitivities were different. Therefore, a larger number of assessors was necessary. The effect of the thickening agent on the sensory rating of acidity was only moderate, but still statistically significant. The correlation between sensory ratings of viscosity and acidity was not significant. In the significance of differences between individual samples, differences were observed depending on the concentrations of methyl cellulose and the acid used.
