| Abstract: | The effect of color, as measured on the Gardner XL-23 calorimeter, on the sweetness perception of a series of lime- and lemon-colored and flavored beverages was quantified by taste panelists using magnitude estimation. The regression lines for each colored series in the lemon drinks were found to differ significantly (p < 0.05) indicating that color had a significant effect on sweetness and the inequality of the slopes of the lines obtained when sweetness was plotted versus log color further confirmed this effect. A sucrose level of 4.4% maximized the effect of color on sweetness perception in both the lime (p < 0.01) and lemon (p < 0.05) drinks. |
