Abstract
Extraction of bioactive molecules has become a major trend in the valorization of food and agroindustrial byproducts, allowing a sustainable production of novel ingredients with different industrial applications. Enzymatic and enzyme-assisted extraction eco-friendly methods could be used to extract value-added compounds from lignocellulosic plant byproducts with interesting biological properties, namely, polysaccharides and polyphenols. Nevertheless, a deep understanding of their enzymatic hydrolytic properties as well as the interactions with the plant cell material is necessary to obtain better extracts with high yields. Therefore, this review focuses on enzymatic treatment of food lignocellulosic byproducts in order to recover bioactive compounds such as polysaccharides and polyphenols.
