Agro-industrial wastes could become a source of revenue through their valorization while reducing their management and disposal issues. In this work, residues from the mango industry have been investigated as a source of sugars for the synthesis of 5-hydroxymethylfurfural (HMF), a high value platform chemical. Mangoes, which were past the last stage of ripening, were used as feedstock for microwave-assisted synthesis of HMF under hydrothermal conditions. The product was quantified through HPLC-DAD. The experimental conditions permitted a maximal HMF yield of 21.2 mol% in a 20-min reaction time at 150 °C with a 1:19 dilution ratio. The advantages of the synthesis pathway include the use of microwave heating and water as solvent media, which renders the reaction pathway eco-friendly. High temperatures and prolonged reaction times seem to lead to unidentified side products which lead to a reduction in HMF yield. The results presented in this work highlight mango fruit waste as a potential biomass for HMF production. This would give value to a current agro-industrial waste while attending to current problems linked to its disposal.

农产品工业废物可以通过增值而成为收入来源，同时减少其管理和处置问题。在这项工作中，已经研究了芒果工业的残留物，作为糖的来源，用于合成高价值的平台化学品5-羟甲基糠醛（HMF）。芒果已超过成熟的最后阶段，被用作在水热条件下微波辅助合成HMF的原料。产物通过HPLC-DAD定量。实验条件允许在150°C下20分钟的反应时间内以1:19的稀释比实现的最大HMF产率为21.2 mol％。合成途径的优点包括使用微波加热和水作为溶剂介质，这使得反应途径生态友好。高温和延长的反应时间似乎会导致产生不确定的副产物，从而导致HMF产量降低。这项工作提出的结果突出了芒果果渣作为HMF生产的潜在生物量。这将为当前的农业工业废物带来价值，同时解决与废物处理相关的当前问题。
