Inulin/PVA biomaterials using thiamine as an alternative plasticizer

In this study, biodegradable biomaterials were prepared by using inulin (INL), PVA and plasticizers (citric acid (CA), glycerol (GL) and thiamine (TH)) with UV curing process. INL was extracted from Jerusalem artichoke flour using hot water extraction method. Extracted INL and INL/PVA biomaterials were characterized by TLC, FT-IR, and SEM analysis. Physical properties such as mechanical and water resistance properties of biomaterials prepared with UV curing time from 0 to 20 min and types of plasticizers were investigated. Their antimicrobial activities, biodegradability, and application of coating materials for foods were also determined. Results indicated that their physical properties were improved by the UV curing process. In addition, physical properties of TH-added biomaterials were 1.5 to 2 times higher than those of GL-added and CA-added biomaterials. Biodegradability in soil revealed that biomaterials were degraded by about 20-40% after 140 days.
