abstract = "The agro-food industry annually produces tons of lignocellulosic waste with an intrinsic high value. Specifically, lignin—an underrated bioresource that is mostly burned for energy production—has a tremendous potential as source of high-value chemicals. A promising lignin valorization requires an efficient extraction process able to recover high-purity lignin with considerable yields. Hence, we describe a protocol to extract lignin from a relevant agro-food residue—brewer{\textquoteright}s spent grain—through the use of a deep eutectic solvent system, which has been proven an excellent potential to promote the fractionation of high-purity lignin from lignocellulosic material. The biomass is subjected to a hydrolysis at 120 °C for 5 h, and the lignin is further recovered by precipitation with distilled water. This protocol gives simple and detailed recommendations to effectively recover lignin from brewer{\textquoteright}s spent grain contributing to the valorization of this abundant residue.",
