Abstract
Formation of low-crystallinity curcumin nanoparticles via controlled supercritical carbon dioxide (SC-CO2) impregnation of curcumin into biodegradable nanoporous starch aerogels and methods of preparing these aerogels are disclosed. The nanoporous starch aerogels increase water solubility and bioaccessibility of the curcumin, thereby making them available for preparation of high nutraceutical value foods.
Claims14
A nanoporous starch aerogel impregnated with curcumin.
A method of forming a nanoporous starch aerogel impregnated with low-crystallinity curcumin, the method comprising:
- forming a nanoporous starch aerogel by:
- exchanging water in a starch hydrogel with ethanolic curcumin solution to form an alcogel;
- and
- SC-CO2 drying the alcogel to form the nanoporous starch aerogel impregnated with low-crystallinity curcumin.
