The effect of poly(vinyl alcohol) (PVA) on the swelling behavior of chitosan (CS) cryogel under simulated digestion.
Chitosan (CS) porous gels (e.g. aerogel, cryogels, and xerogels) are promising carriers for nutrients and bioactive compounds in the gastrointestinal tract, but their poor stability under digestive conditions limits their application. This study investigated the effects of 0-5 wt% poly(vinyl alcohol) (PVA) on the micro...
