Title: Ethyl Acetate Decaffeination
Post by: Zampa on February 26, 2020, 06:51:24 AM
Hello everyone,,
I'm trying to decaffeinate some specific teas that are not sold decaf. I've read some papers on it and have settled on an ethyl acetate based extraction. In lieu of the mild health risks posed by ethyl acetate, would washing tea leaves in this then drying them at 200F leave behind any harmful residues?

Also does the purity of ethyl acetate matter? I've found them ranging from unlabeled to 99.9%.
