I know that TSP is a GRAS food additive but has anyone used it for sanitation/deep cleaning before?
We roast coffee beans and currently our procedure for deep cleaning the afterburner and pipes has been to using a metal scraper to scrap off the soot and chaff build up which was then replaced by a wire brush attachment onto a power drill.
We were advised by a coffee roaster maintenance tech (50+ years working with roaster equipment) to soak the pipes in a TSP water solution. We have not moved forward with this method yet but I am concerned if it is prohibited by organic standards and environmental purposes. We are certified to the USDA organic regulations, 7 CFR Part 205. I was looking at the NOP list but I did not see anything regarding TSP. I also read up that TSP is very bad for the environment.
Any input is greatly appreciated!
