The demands for better-tasting alternative sweeteners have driven efforts to improve the sensory properties of rebaudioside A (Reb-A), such as glycosylation and blending with bulk sweeteners. This study attempted to (i) investigate the sensory profiles of a novel sweetener, glycosyl rebaudioside A (gReb-A), and its 1:1 mixtures with erythritol or maltitol, and (ii) compare between the sensory characteristics in an aqueous solution and lemonade. The concentrations of the sweeteners were prepared to match the sweetness intensity of a 7% (w/v) sucrose solution using relative sweetness values determined using the two-alternative forced-choice test. Eight trained panelists identified sensory profiles of the sweeteners in an aqueous solution and lemonade using a descriptive anal. protocol. gReb-A had significantly less bitterness and lingering sweetness than Reb-A did, eliciting a sensory profile similar to that of sucrose. The mixture of gReb-A and erythritol was not sensorially differentiated from the sucrose in the aqueous solution Blending with maltitol significantly enhanced the sweetness and suppressed the bitterness of gReb-A. gReb-A and its binary mixtures were perceived as more similar to sucrose in the lemonade than in solution This study suggests that glycosylation and blending with erythritol and maltitol gave a more sucrose-like sweetness profile in the aqueous solution and lemonade. The results of the study can be used to develop adequate sugar substitutes for acidic beverages. 2021 Society of Chem. Industry. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Application In Synthesis of (2R,3S)-rel-Butane-1,2,3,4-tetraol).
(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Application In Synthesis of (2R,3S)-rel-Butane-1,2,3,4-tetraol
