Layered taste-masking: sweeteners (e.g., sucralose/ace-K/erythritol) + acidity modulation (citric/malic) + flavors (mint, citrus, berry, herbal) + cooling agents (menthol/WS series) for staged release and reduced irritation.
Release curve design: pH buffering and excipient synergy to shape “entry–mid–finish” within a 30–120 s disintegration window; sugar-free/low-sugar and low-allergen options available.
Process compatibility: polymer/plasticizer ratios, solids content, and coat weight tune flavor loading and diffusion; avoid dose-driven harshness or film brittleness.
Data & evaluation: trained panel scoring, triangle tests, time–intensity (TDS) and spider charts; link to accelerated/long-term stability to confirm aroma retention and aftertaste control.
Compliance & labeling: jurisdictional limits for sweeteners/cooling agents/flavors; ingredient disclosure, allergen statements, and adults-only usage.
