I found a homemade enteric coating. Naturally only food quality ingredients should be used. It consists of using shellac flakes dissolved in ethanol to coat a gel capsule with a sprayer. The shellac will dissolve in the alkaline conditions of the lower intestine but not the acidic stomach. Shellac apparently is not only a fine wood varnish but is non toxic as it is produced by a insect for cocooning and is used on supermarket fruit along with wax as well as the pharmacuetical industry.
