Abstract:

A review. There is an increasing tendency towards the development of food, cosmetic and pharmaceutical products contg. only natural ingredients. Many proteins and polysaccharides extd. from nature can be used as functional ingredients to form colloidal systems suitable for use in industrial products. These colloidal systems can be fabricated using a variety of physicochem. and processing approaches. This chapter focuses on the fabrication and properties of sub-micron to micron-sized colloidal particles, formed by controlled aggregation/complexation of mixed biopolymer systems. The processes used to fabricate these particles include treatments of globular protein and/or polysaccharide solns. at select temps., pH, ionic strengths, and/or solvent qualities. Potential applications of the biopolymer colloidal particles are discussed. [on SciFinder(R)]
