  "abstract": "<p>This study has two targets: Studying the extraction of the initial protein content from brewer&rsquo;s spent grain and the impact of protein&rsquo;s extraction on the chemical-physical properties of produced hydrochars. The protein was extracted from brewer&rsquo;s spent grains using the pH-shifting method. The extracted protein was quantified and characterized by their amino acid profile. The hydrothermal treatment was applied at 190 &deg;C and 220 &deg;C for 0.5 h, 1h, 2 h, and 4h. The hydrochars and process water were collected and assayed. The hydrochar after protein extraction reveals the lowest yield to hydrochars (67.10 &ndash; 45.14 %), higher C/N ratio (19.66 - 21.33) and lower ash content (1.52 &ndash; 1.72 wt. %) compared to the hydrochar without extraction.</p>",
