During the last decade, pressure intensified technologies have become more attractive and competitive alternatives for several industrial processes. A growing interest in safe and environmentally friendly products, the increasing availability of industrial-scale commercial units, and the stricter regulations are the main reasons behind this phenomenon. In particular, supercritical and subcritical fluid technologies offer suitable alternatives for the processing of citrus fruits. On the one hand, these technologies can replace conventional processes all along the production chain, i.e., peel oil refinement, preservation of organoleptic properties of juices, pectin extraction, etc. On the other hand, the selective green solvents used in these technologies allow obtaining high-quality and high-value-added products from citrus fruit waste. In this review, the most significant achievements in the processing of citrus fruits and derived wastes by innovative supercritical and subcritical fluid technologies are presented. Advantages and drawbacks against conventional processes, as well as future perspectives, are discussed.

在过去的十年中，压力强化技术已成为多个工业流程更具吸引力和竞争力的替代方案。对安全和环保产品的兴趣日益浓厚、工业规模商业单位的日益普及以及更严格的法规是这一现象背后的主要原因。特别是，超临界和亚临界流体技术为柑橘类水果的加工提供了合适的替代方案。一方面，这些技术可以取代整个生产链中的传统工艺，即果皮精炼、果汁感官特性的保存、果胶提取等. 另一方面，这些技术中使用的选择性绿色溶剂可以从柑橘类水果废料中获得高质量和高附加值的产品。在这篇综述中，介绍了创新的超临界和亚临界流体技术在处理柑橘类水果和衍生废物方面取得的最重要成就。讨论了相对于传统工艺的优点和缺点，以及未来的前景。
