Abstract

β-glucan freeze-thaw gel was used as a carrier to release curcumin. The results showed that the freeze-dried gel had the ideal sustained release following 5% β-glucan solution by adding 1% β-glucan quality curcumin, repeated freezing and thawing 8 times. The Peppas equation can significantly describe the release mechanism of curcumin in the β-glucan gel. This study further demonstrated that the release of curcumin in the oat β-glucan gel is the Fick diffusion mechanism and coated barley β-glucan is a non-Fick spread.
