摘要

目的旨在通过全藕粉低共熔溶剂（DES）上清液,引入天然黄酮多酚活性成分,优化氧化淀粉薄膜的力学性能和抗氧化能力,以拓展其应用。方法以氧化淀粉为原料,添加羧甲基纤维素钠制备生物质膜材料,并采用不同DES（氯化胆碱-乙二醇二元DES及氯化胆碱-乙二醇-山梨醇三元DES）提取全藕粉上清液,将其作为增塑剂和抗氧化增强剂引入薄膜体系。通过紫外-可见分光光度法测定DPPH清除率,筛选最优DES配方;结合傅里叶变换红外光谱（FTIR）、热重分析（TG）和拉伸性能测试,分析薄膜的结构与性能。结果氯化胆碱-乙二醇二元DES提取的全藕粉上清液中多酚黄酮总量达29.19 mg/g,DPPH清除率为85.53%;优化后的三元DES（含山梨醇）提取效率进一步提升,多酚黄酮总量达34.84 mg/g,DPPH清除率达89.34%。所制备的三元DES改性生物质膜表现出优异的综合性能：DPPH清除率为41.5%,拉伸强度达5.07 MPa,断裂伸长率提升至295.55%。结论全藕粉DES上清液通过氢键作用有效改善了氧化淀粉薄膜的力学性能,同时赋予其抗氧化能力。三元DES的引入进一步提升了薄膜的延展性和活性成分负载量,为高性能可降解生物质膜材料的开发提供了可行策略。

Abstract

The work aims to optimize the mechanical properties and antioxidant capacity of oxidized starch films by incorporating lotus root powder-based deep eutectic solvent (DES) supernatant, which contains natural flavonoid and polyphenol active components, thereby expanding its potential applications. With oxidized starch as the raw material, biodegradable biomass film materials were prepared by adding sodium carboxymethyl cellulose. Different DES systems (binary DES composed of choline chloride-ethylene glycol and ternary DES composed of choline chloride-ethylene glycol-sorbitol) were employed to extract the supernatant from lotus root powder, which was then introduced as a plasticizer and antioxidant enhancer into the film matrix. The DPPH radical scavenging rate was measured via UV-Vis spectrophotometry to screen the optimal DES formulation. The structural and functional properties of the films were analyzed by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and tensile testing. The binary DES (choline chloride-ethylene glycol) extracted lotus root powder supernatant contained total flavonoids and polyphenols up to 29.19 mg/g, with a DPPH scavenging rate of 85.53%. The optimized ternary DES (with sorbitol) further improved extraction efficiency, achieving 34.84 mg/g of total flavonoids/polyphenols and an 89.34% DPPH scavenging rate. The ternary DES-modified biomass film exhibited outstanding comprehensive performance: a DPPH scavenging rate of 41.5%, tensile strength of 5.07 MPa, and elongation at break of 295.55%. In conclusion, the lotus root powder DES supernatant effectively enhances the mechanical properties of oxidized starch films through hydrogen bonding while imparting antioxidant functionality. The ternary DES further improves film flexibility and bioactive compound loading, providing a feasible strategy for developing high-performance biodegradable biomass film materials.
