Consider it for how processed a specific brand of food is, rather than a general food. Right now most specifications don’t get more specific than organic, free range, grass fed, vegan, all natural, no preservatives, etc. I suspect the problem would lie in data quality more than deriving insights.
For example: a sliced apple is technically processed food, but what is it sprayed with?
Usually hydrogen peroxide[0] (when sliced) but if you are referring to what chemicals a farm uses, that would be really, really hard to provide. I believe Chipotle tried to do a farm to store supply chain doc and gave up and went with a distributor. However, they still are trying w/ robotics and other initiatives.[1]
At the end of the day, how do you really know what chemicals are used on the farm? The cost of tracking anything is astronomical. I.E. cost of a bolt in airline industry.
Lastly, at least for food: producers, distributors, end-users (stores), and everyone else uses different software with proprietary protocols and the margins don't really incentivize anyone from switching.
