摘要

紫外辐照和热处理是公认的环保方法，被广泛应用于淀粉的改性。研究了一种新型连续流系统，利用H2O2和CuSO4的混合物，在波长254 nm的紫外线C （UVC）照射和50°C的热暴露下，对玉米淀粉进行fenton样氧化。分别通过单因素设计和正交设计对实验装置参数进行优化。两种处理的最佳条件为：淀粉浆的pH值为5.0，辐照时间为60 min，氧化剂和催化剂的浓度分别为2%和0.5%。在优化后的条件下，比较了H2O2/Cu2+和H2O2单独与UVC和热联合使用对天然淀粉理化性质和结构性质的影响。H2O2/Cu2+/Heat处理（0.461%）和H2O2/Cu2+/UVC处理（0.378%）的氧化程度均高于其他处理。结果表明，与UV-C辐照相比，热处理对氧化淀粉性质的影响更为明显。生态尺度方法验证了所设计的淀粉氧化处理的绿色性质。

Comparative study of UVC irradiation and heat treatment on Fenton-like oxidation of corn starch in a continuous flow system: Performance and greenness

UV irradiation and heat treatment, recognized as environmentally friendly methods, are extensively applied in modifying starch properties. The current work presented Fenton-like oxidation process of corn starch using a blend of H₂O₂ and CuSO₄ under ultraviolet C (UVC) irradiation (wavelength of 254 nm) and heat exposure (50 °C) within a novel continuous flow system. The parameters of the experimental setup were separately optimized through one-factor-at-a-time and orthogonal design. The optimal conditions for both treatments included the pH value of 5.0 for starch slurry, irradiation duration of 60 min along with oxidant and catalyst concentrations of 2 % and 0.5 %, respectively. Under the optimized conditions, the effect of using H₂O₂/Cu²⁺ or H₂O₂ alone in combination with UVC and heat on physicochemical and structural attributes of native starch was compared. The higher oxidation degree was obtained for treatments of H₂O₂/Cu²⁺/Heat (0.461 %) and H₂O₂/Cu²⁺/UVC (0.378 %) compared to the other treatments. The findings showed that thermal treatment exerted a more pronounced influence on properties of oxidized starches compared to UV-C irradiation. Eco-scale methodology verified the green nature of the designed treatments for the starch oxidation.
