NANOPOROUS STARCH AEROGELS IMPREGNATED WITH PHYTOSTEROLS AND METHODS OF PREPARING THE NANOPOROUS STARCH AEROGELS

摘要

Formation of low-crystallinity phytosterol nanoparticles via cooling-controlled supercritical carbon dioxide (SC—CO₂) impregnation of phytosterols into biodegradable nanoporous starch aerogels and methods of preparing these aerogels are disclosed. The nanoporous starch aerogels increase water dissolution and bioaccessibility of the phytosterols, thereby making them available for preparation of high nutraceutical value foods.
