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.
本研究采用菊粉（INL）、PVA 和增塑剂（柠檬酸（CA）、甘油（GL）和硫胺素（TH）），通过 UV 固化工艺制备可生物降解的生物材料。菊粉从菊芋粉中采用热水提取法提取。通过 TLC、FT-IR 和 SEM 分析对提取的 INL 和 INL/PVA 生物材料进行了表征。考察了 UV 固化时间从 0 分钟到 20 分钟和增塑剂类型对制备的生物材料的机械和耐水性等物理性能的影响。还测定了它们的抗菌活性、生物降解性以及作为食品涂层材料的应用。结果表明，UV 固化工艺提高了它们的物理性能。此外，添加 TH 的生物材料的物理性能比添加 GL 和 CA 的生物材料高 1.5 至 2 倍。在土壤中的生物降解性表明，生物材料在 140 天后降解了约 20-40%。
