Absolutely not someone in that or any adjacent industry, so I would not know whether that's a usable solution. Could work, I mean it is used for gummi bears. But there might also be a thing about how it only lasts in closed packs I would imagine, and unlike gummi bears - which are gone ~11,5 seconds after opening a pack - straws are often kept around for months after a few have been used. No clue. There's probably a better solution than PFAS coating though, granted.
