    Recovery of high value‐added protein from enzyme‐assisted

    The skim fraction (SF) is an aqueous phase that contains a small amount of emulsified oil and soluble saccharides and a significant amount of soybean protein (de Moura et al., 2013). It was estimated that almost 27 L of SF was produced for every liter of soybean oil extracted (Yao, Wang, & Wang, 2011 ).

    The enzyme-assisted aqueous extraction process (EAEP) is an environmentally friendly strategy that simultaneously extracts oil and protein from several food matrices. The aim of this study was to investigate the effects of pH (6.5–9.5), temperature (45–55 °C), solids-to-liquid ratio (SLR) (1:12–1:8), and amount of enzyme (0.5–1.0%) on the extraction and separation
