Because food byproducts (waste) are rich in phytoconstituents, valorizing them is crucial for global food security. However, conventional extraction (CE), including decoction, maceration, Soxhlet, etc., for agro byproducts' polyphenol extraction are time-consuming and rely significantly on vast volumes of potentially aggressive solvents. Hence, Avantgarde extraction technologies, including non-thermal (high hydrostatic pressure (HHPE), pulsed-electric field (PEF), high voltage electrical discharges (HVED), etc.) and thermal extraction (supercritical fluid (SCF), subcritical water extraction (SWE), microwave-assisted extraction (MAE), etc.), as well as their thermal combinations (SCF-PLE, SCCO-SWE, SCCO-MAE, etc.), non-thermal combinations (HHPE + UAE, PEF + UAE, HVED + UAE, etc.) and combined thermalnon-thermal (MAE-UAE, etc.) are increasingly replacing CE. However, a review of combined Avant-garde extraction escalation technologies (non-thermal/thermal extraction matrix) for extracting polyphenols from agro-byproducts is limited. Hence, this manuscript reviewed Avant-garde extraction technologies (non-thermal/thermal extraction matrix) for extracting phenolics from agro-byproducts in the last 5 years. The key factors affecting polyphenols' extraction from the byproduct, the recent applications of Avant-garde technologies, and their principle were reviewed using databases from Web of Science and Lens.org. The results demonstrated that combined Avant-garde extraction escalation technologies increase extractability, resulting in polyphenols with higher extraction rates, fewer contaminants, and preservation of thermosensitive components. Therefore, combined Avant-garde extraction technologies should be explored over the next five years. Implementing an integrated process and the strategic sequencing of diverse Avant-garde extraction technologies are important. Thus, further investigation is required to explore the sequencing process and its potential impact on the extraction of phenolics from agro-byproducts.
由于食物副产物（废物）富含植物成分，因此对其进行增值利用对于全球粮食安全至关重要。然而，传统的提取方法（CE），包括煎煮、浸渍、索氏提取等，用于农业副产物中多酚的提取耗时较长，并且严重依赖于大量潜在的有侵略性的溶剂。因此，先进的提取技术，包括非热（高压静水压力（HHPE）、脉冲电场（PEF）、高压放电（HVED）等）和热提取（超临界流体（SCF）、亚临界水提取（SWE）、微波辅助提取（MAE）等），以及它们的热组合（SCF-PLE、SCCO-SWE、SCCO-MAE 等）、非热组合（HHPE + UAE、PEF + UAE、HVED + UAE 等）和组合的热非热（MAE-UAE 等），正在逐渐取代 CE。然而，对于从农业副产物中提取多酚的先进联合提取升级技术（非热/热提取基质）的综述仍然有限。因此，本文综述了过去 5 年来从农业副产物中提取酚类物质的先进提取技术（非热/热提取基质）。使用 Web of Science 和 Lens.org 数据库，综述了影响副产物中多酚提取的关键因素、先进技术的最新应用及其原理。结果表明，联合先进提取升级技术提高了提取能力，从而获得了具有更高提取率、更少污染物和热敏性成分保留的多酚。因此，在未来五年内，应该探索联合先进提取升级技术。实施综合工艺和多样化先进提取技术的战略排序非常重要。因此，需要进一步研究探索序列过程及其对农业副产物中酚类物质提取的潜在影响。
