Hydrated Sensory Signatures: An OUXSPACE Model of Water-Interface Modulation in Olfaction, Taste, and Flavor

This theoretical OUXSPACE paper proposes that olfaction, taste, flavor, and odor-based state modulation should be considered not only through isolated molecular structure or receptor engagement, but through hydrated sensory signatures formed at living aqueous interfaces. The model introduces the nasal mucus, saliva, local hydration shell, ionic environment, proton behavior, and receptor-proximal surfaces as a physicochemical conditioning layer before and during biological recognition. The paper distinguishes between an established physicochemical context, an OUXSPACE hydration-interface hypothesis, and an optional extended microtubule-associated biological-interface layer. The 4-/6-/8-/10-water motifs are presented as regimes developed within the preceding OUXSPACE closure framework, while their sensory-interface population dominance, lifetimes, free-energy profiles, and experimental readouts remain open to validation through MD/DFT, receptor-proximal systems, and controlled sensory studies.
