    Destabilization of the emulsion formed during the enzyme

    In this study, we propose the destabilization of the emulsion formed in the EA-AEP of full-fat soybean flour through the addition of enzymes (1) to hydrolyse the interfacial proteins, reducing the rigidity of the oil droplet interface, or (2) to hydrolyze the phospholipids, eliminating their surface activity, thus permitting oil droplet aggregation/coalescence.

    Aqueous extraction involves water as a medium to extract the oil from oilseeds. It is well known that the lipid molecules are amphipathic in nature and the water soluble components diffuse into water which culminates into emulsion formation. The emulsified oil in water can be de-emulsified by changing the temperature or deploying enzymes.
