With the main aim of developing soy protein drag delivery systems for different tissue regeneration applications, various processing techniques are being studied in our research group. A wide range of shapes and processing methods could already be developed. This includes membrane, microparticles and thermoplastic systems. The resulting soy membranes, microparticles, and thermoplastics are intensively characterised and their potential use as drag delivery systems, especially as pH-sensitive systems, is discussed. The use of protein modifications, namely crosslinking, for the improvement of functional properties relevant for each specific application is also addressed in this chapter.
