The release profiles of bovine serum albumin nanoencapsulated into an enteric copolymer (methacrylic acid/ethyl acrylate blended with poly (ethylene glycol)) show an effective protection for this protein from the stringent pH gastric environment. The nanoParticles (nP) yield of about 90% and encapsulation efficiency of 77–78% indicate a successful control of the process. The experimental evidence leads to physical entanglements between PEG and the copolymer be considered as the driving factor to modulate the release.
