Fruit and Beverage Profiles:柑橘油、薄荷提取物及浆果类萜烯成分极为疏水。通过制备纳米级的油包水(O/W)乳液(常采用高剪切均质技术),这些油脂可以在PG/水的连续相中纯净悬浮。
Coil Lifespan:O/W systems tend to vaporize cleanly. Because the continuous phase is water/PG, it atomizes easily on the heating element, carrying the micro-droplets of flavor oil with it. This prevents the rapid accumulation of carbonized lipids on the coil, a common issue known as "coil gunking."
Cream, Custard, and Bakery Profiles:水包油(W/O)乳液带来截然不同的感官体验。持续的油相包裹味蕾,延缓水溶性挥发性化合物的释放,造就持久浓郁、丝滑细腻的口感,尤为适合浓厚甜点、奶油布丁及复杂烟草调配的风味表现。
Protection of Volatile Top Notes:Highly volatile, water-soluble aroma chemicals (like certain esters that provide "candy" or "jam" notes) can degrade quickly or evaporate prematurely. By encapsulating them within a continuous oil phase (W/O), the oil acts as a protective barrier, preserving the top notes during storage and altering the vaporization curve for a smoother inhale.
This is driven by gravity and the density difference between the oil and water phases, governed by Stokes' Law. In an O/W emulsion, if the oil is less dense than the water/PG, the droplets will rise to the top (creaming). If the dispersed phase is denser, it will sink (sedimentation).
Solution:Incorporate a highly insoluble "ripening inhibitor" (like a heavy, long-chain triglyceride) into the dispersed oil phase to alter the entropy of mixing and halt the mass transfer.
