Production of corn zein microparticles with loaded lysozyme directly extracted from hen egg white using spray drying: Extraction studies

Feasibility of achieving sustained release of lysozyme by encapsulation in corn zein using spray drying was examined. To reduce the materials cost, this part of work focused on partially purifying lysozyme from hen egg white using 30–90% (v/v) aqueous ethanol, adjusted to pH 3.0–9.24. After extraction for up to 24 h and centrifugation, the purification performance was evaluated for the supernatant. Extraction was insignificantly affected by...
