The freeze-dried gel has the ideal sustained release following 5% ¦Â-glucan solution by adding 1% ¦Â-glucan quality curcumin, repeated freezing and thawing 8 times. The Peppas equation can significantly describe the release mechanism of curcumin in the ¦Â-glucan gel. This study further shows that the release of curcumin in the oat ¦Â-glucan gel is the Fick diffusion mechanism and coated barley ¦Â-glucan is a non-Fick release. Trying to use ¦Â-glucan as a completely natural drug delivery carrier opens up new ideas for the use of ¦Â-glucan. http://pubs.sciepub.com/jfnr/8/9/3/jfnr-8-9-3.pdf cryogelation curcumin sustained-release non-Fick
