Large amounts of agri-food by-products, non-edible food, and waste are produced throughout the supply chain from the initial production to the final consumption stages. The valorization of this biomass to obtain high value-added compounds has been the focus of extensive research in the last decade. For this purpose, the use of green techniques is essential to reduce the negative impact on the health and the environment. In this review, we discuss the use of green solvents for the valorization of agri-food waste and by-products, and we consider their potential to replace conventional organic solvents in order to provide more environmentally friendly and sustainable processes. The use of supercritical fluids, neoteric (ionic liquids and deep eutectic solvents), bio-based, and supramolecular solvents is critically dicussed. Parameters affecting extraction efficiency are detailed for each type of solvent along with advantages and limitations for application at the industrial scale.

从最初的生产到最终的消费阶段，整个供应链中都会产生大量的农业食品副产品，非食用食品和废物。在过去的十年中，这种生物质的增值以获得高附加值的化合物一直是广泛研究的重点。为此，使用绿色技术对于减少对健康和环境的负面影响至关重要。在这篇综述中，我们讨论了绿色溶剂用于农业食品废物和副产品的增值的方法，并且我们考虑了绿色溶剂替代传统有机溶剂的潜力，以提供更环保和可持续的工艺。严格禁止使用超临界流体，新型（离子液体和深共熔溶剂），生物基和超分子溶剂。
