Pressurized hot water extraction (PHWE) is a sustainable technique that represents an alternative to conventional methods using organic solvents. It enables the recovery of bioactive compounds, such as phenolic proteins, and polysaccharides, among others, from different natural sources. Hence, primary objective this review offer brief overview on PHWE fundamentals, providing up-to-date account its applications in compounds 2019 present. This builds upon previous works (Plaza Turner (Trends Analytical Chemistry 71 (2015) 39–57) Plaza Marina 116 (2019) 236–247)). Additionally, highlights latest trends PHWE, including combination with other advanced techniques well use deep eutectic solvents modifiers, enhance yields. These advances aim improve efficiency versatility technique.

Almond skin (AS) is an agro-industrial residue from almond processing that has a high potential for valorisation. In this study, subcritical water extraction (SWE) was applied at two temperatures (160 and 180 °C) to obtain phenolic-rich extracts (water-soluble fraction) cellulose fibres (insoluble AS. The conditions affected the composition properties of both valorised fractions. dry obtained °C were richer in phenolics (161 vs. 101 mg GAE. g−1 defatted (DAS)), with greater antioxidant (1.063 1.490 DAS.mg−1 DPPH) showed antibacterial effect (lower MIC values) against L. innocua (34 90 mg·mL−1) E. coli (48 than those 160 °C, despite lower total solid yield (21 29%) SWE process. purification residues, using hydrogen peroxide (H2O2), revealed AS not good source material since bleached fractions low yields (20–21%) purity (40–50%), even after four bleaching cycles (1 h) pH 12 8% H2O2. Nevertheless, application green, scalable, toxic solvent-free process highly useful obtaining bioactive different food, cosmetic, or pharmaceutical applications.
