I've got a constantly growing dataset of price and quantity history for all products in one supermarket's database (Ocado, the online-only supermarket in the UK I shop at). Doesn't include ingredients at the moment, but I do like the idea of that. Also only a few months of data so far.
Anyway, I've made it available as a website in a way that is hopefully useful – it is to me at least: https://ocamatic.uk/
Related to this, I'm in the UK and use online-only supermarket Ocado. And I recently built https://ocamatic.uk/, which scrapes price history for all products. I use it to check how often a given product is on sale, for example. It also shows recent "shrinkflation" events. Maybe others will find it useful.
