What's the best way to filter the USDA food database by proces | Data Scientology

What's the best way to filter the USDA food database by processing amount?

I'm doing a project on the nutrient difference between minimally processed plant and animal foods, i downloaded the whole usda dataset but there's not a single file with processing amount tag, what's the best way to go about this?

i can use chemicals that are commonly added.. but some of them are naturally found in foods, i can go through manually and remove rows with certain keywords (with added, flavored, mcdonald, etc..) but that is manually and it will never be completely accurate unless i somehow go through all the 1.7m entries.

any advice on how i can tackle this issue?
