Is it obligatory to make up the fast for one who tasted the flavor of juice powder in his throat then expelled it during Ramadan?

What entered your stomach from what was mentioned does not invalidate your fast, nor does it require you to make up for it, because what enters the stomach and is widespread and difficult to guard against, such as road dust and similar things, is excused. The proof for this is that the unintentional is excused, otherwise, it would necessitate burdening someone with what they cannot bear.
