Is there a physicochemical explanation why hot tea loses his aroma in a thermoscontainer?
Odor compounds are usually volatile and short lived. If you keep tea in a thermos all day, many of the complex and delicate flavor and odor compounds could simply have broken down and disappeared. I wouldn't blame the thermos- it's more likely time that washed away the aroma.Oh, and it could be that your thermos is dirty or harboring other odors. Just double check~

Why does the hot tea in a Thermos flask remain hot for a long time?
The Thermos (vacuum) flask has a double skinned glass cylinder inside. Between the two walls of the glass cylinder is a vacuum. The glass cylinder is also silvered on all inner and outer surfaces. Both the vacuum and the silvering help to prevent the rapid cooling of a hot liquid, or the warming of a cold liquid. The vacuum inhibits heat transfer by conduction. The silvering reflects the heat and inhibits the heat escaping from the flask. Thermos (often used for a vacuum flask) is a trade-name.Eventually, as anyone who uses a vacuum flask, the once hot drink will have become cool by the end of the day.
