The purpose of this research is to study the effect of the steam explosion (SE) process on curcumin extraction from fresh turmeric chips. Fresh turmeric chips abruptly disintegrated during the steam explosion process. The investigation into the turmeric particles following the steam explosion process in the SEM micrographs revealed that the formation of surface cracks and cavities led to an increase in the surface area of turmeric particles. Curcumin extracted from turmeric particles after the steam explosion process yielded 3.24% (/), which was comparable to the yield of 3.98% (/) from finely ground turmeric particles, while the steam explosion used 74% less energy than the grinding process. Therefore, the steam explosion process is an efficient process compared to untreated and conventional mechanical grinding methods. On average, the turmeric particles decreased in size when the dissipated energy per mass increased. The curcumin yield from the steam explosion exhibited a linear positive correlation with the dissipated energy per mass. FTIR, TG/DTG, and DSC analyses on the turmeric particles after the steam explosion process showed that the compounds exhibited no change in chemical structure, higher thermal decomposition properties, and higher purity, respectively. The results of this research can be applied to find optimal conditions for extracting curcumin and predicting the yield of curcumin. Additionally, they can be applied to evaluate the process condition in commercial applications.
本研究的目的是研究蒸汽爆破（SE）工艺对从新鲜姜黄片中提取姜黄素的影响。新鲜姜黄片在蒸汽爆破过程中会突然崩解。对蒸汽爆破后的姜黄颗粒进行扫描电子显微镜（SEM）图像研究发现，表面裂纹和空洞的形成导致姜黄颗粒表面积增加。蒸汽爆破后的姜黄颗粒提取的姜黄素产率为3.24%（/），与细磨姜黄颗粒3.98%（/）的产率相当，而蒸汽爆破比研磨过程能耗低74%。因此，与未处理和传统机械研磨方法相比，蒸汽爆破工艺是一种高效的工艺。平均而言，当单位质量耗散能量增加时，姜黄颗粒尺寸减小。蒸汽爆破的姜黄素产率与单位质量耗散能量呈线性正相关。对蒸汽爆破后的姜黄颗粒进行傅里叶变换红外光谱（FTIR）、热重/微商热重（TG/DTG）和差示扫描量热法（DSC）分析表明，这些化合物的化学结构没有变化，热分解性能更高，纯度也更高。本研究结果可用于寻找提取姜黄素的最佳条件并预测姜黄素的产率。此外，它们还可用于评估商业应用中的工艺条件。
