Abstract
Background
This study examines the physicochemical interactions between taurine and caffeine in aqueous solutions. Caffeine's limited solubility and tendency for self-association present challenges in food and pharmaceutical applications. Taurine, frequently found in energy drinks and supplements, may influence caffeine's solubility, structural organization, and sensory properties.
Methods
This research utilized a combination of experimental techniques and computational simulations. Volumetric, acoustic, and viscosimetric measurements were performed from T = 293.15 K to 313.15 K. Precise gravimetric methods determined the solubility of taurine in water and caffeine in taurine solutions. Molecular dynamics simulations provided insights into hydration and self-aggregation behaviors.
Significant findings
The results reveal that taurine significantly affects caffeine's physicochemical properties. In aqueous solutions, the presence of taurine has been observed to marginally improve caffeine's solubility compared to pure water. Our research substantiates that the precarious stability of caffeine molecules in water can be notably disrupted through the introduction of polar additives, exemplified by taurine. Thus, a considerable transformation in the molecular architecture of caffeine environment.
