Answered by Shaykh Faraz Rabbani
If their remains a taste of food in ones mouth and teeth, and if one swallows this, after the fast has begun, does it invalidate it?

Walaikum assalam,
The presence of mere taste, without any actual trace of the food or item ingested, would not in itself invalidate the fast.
Wassalam,
