Description
Summary:Stevia is an emerging natural high-intensity sweetener. There are negative perceptions of zero-calorie sweeteners, but studies that provide knowledge of these sweeteners improve their perception. This study evaluated consumer acceptability of a zero-sugar bakery product under blind and informed conditions (n = 96) along with physicochemical analysis of the products. Rebaudioside A (Reb A) and the new types of stevia (Rebs D and M) with sugar as a control were used to formulate pound cakes. Panelists evaluated the overall hedonic impressions (aroma, texture, flavor, and aftertaste) and intensity (sweetness and bitterness) of the cakes under blind and informed conditions with an enforced 2-week break between evaluations. During the informed session, a document was provided prior to evaluating samples that included stevia's health benefits and the nutritional facts panels for the cakes. The cakes underwent volatile profile (electronic nose [e-nose]) and water activity (a ) analysis. Overall, stevia cakes showed an increase in flavor and texture liking during the informed session when compared to the blind session, but only Reb A showed a significant difference (p
