Yep we do.

The Dextrose is for browning.
's a vicious circle though, isn't it...
I've noticed - mainly because I'm not adverse to buying potatoes on yellow sticker - that different varieties behave differently when I turn them into chips. Some brown far more quickly than others, which is, as you infer due to added dextrose, down to a higher sugar content.
Guess you could do away with the dextrose by changing to a different variety of potato, but it's never that simple. Specially when it's better to have a potato that gives a good yield to satisfy demand. And of course, it's law of sod that there's not going to be much overlap between the two...
Chapeau!

Spring asparagus and boiled bintjes is a northern European culinary delight....
Bintjes are colloquially known in the coastal West Flanders where mum hails from as Duine Pataten aka dune potatoes. They need a sandy and free draining soil to thrive, which we generally don't have over much of in the UK. They'd just get waterlogged and rot in heavy fen soil.
