The primary objective of the Sustainable Development Goals is to reduce food waste by employing various strategies, including the reuse of agri-food residues that are abundantly available and the complete use of their valuable compounds. This study explores the application of high-pressure homogenization (HPH), an innovative nonthermal and green treatment, for the recovery of bioactive compounds from agri-food residues. The results demonstrate that the optimized HPH treatment offers advantages over conventional solid/liquid extraction (SLE), including shorter extraction time, solvent-free operation, low temperatures, and higher yields of phenol extraction (an approximately 20% improvement). Moreover, the micronization of agri-food residue-in-water suspensions results in a decrease in the size distribution to below the visual detection limit, achieved by disrupting the individual plant cells, thus enhancing suspension stability against sedimentation. These findings highlight the potential of HPH for environmentally friendly and efficient extraction processes.
可持续发展目标的主要目的是通过采用各种策略减少食物浪费，包括重新利用大量存在的农业食品残渣，并充分利用其有价值的化合物。本研究探讨了高压均质（HPH）的应用，这是一种创新的非热和绿色处理方法，用于从农业食品残渣中回收生物活性化合物。结果表明，优化的 HPH 处理比传统的固/液萃取（SLE）具有优势，包括提取时间更短、无溶剂操作、低温和更高的酚类提取产量（提高约 20%）。此外，农业食品残渣-水悬浮液的微米化导致尺寸分布降至低于视觉检测限，这是通过破坏单个植物细胞来实现的，从而提高了悬浮液对沉降的稳定性。这些发现突出了 HPH 在环保和高效提取过程中的潜力。
