Abstract Food waste (FW) has a high organic content, but its moisture content (up to 75–95%) limits its application. Improvement of dehydration has great significance for the subsequent treatment. This study investigated the influences of gamma-ray irradiation on the dehydration performance of rice waste, a major ingredient of FW. The measurement of mechanical centrifugation dehydration, moisture distribution and bond energy (Hb) indicated that the supernatant volume, free moisture content and decrease in bonding energy is significantly enhanced by gamma-ray irradiation. Moreover, the mechanism of dehydration performance enhancement was discussed based on particle size analysis, reducing sugar (RS) content, UV–Vis spectrum and pH-value.

伽马射线辐照提高大米废料的脱水性能

摘要 餐厨垃圾（FW）的有机物含量高，但其水分含量（高达 75-95%）限制了其应用。脱水的改善对后续处理具有重要意义。本研究调查了伽马射线辐照对大米废料（FW 的主要成分）脱水性能的影响。机械离心脱水、水分分布和键能 (Hb) 的测量表明，伽马射线辐照显着增强了上清液体积、游离水分含量和键能降低。此外，基于粒度分析、还原糖 (RS) 含量、紫外-可见光谱和 pH 值讨论了脱水性能增强的机制。
