Popis: Nanosized and water-soluble complexes have been formed between biopolymers (a covalent conjugate of sodium caseinate with maltodextrin) and essential lipids. These lipids were liposomes of soy phosphatidylcholine (PC: 59% omega-6 linoleic acid (LA); 7% omega-3 alpha-linolenic acid (ALA)) enriched by omega-3 ALA as a constituent of triglycerides of linseed oil (LO: 55% ALA; 18% LA). They were prepared without and with such plant antioxidant as an essential oil of clove bud (EOC). The basic relationships have been revealed between functional properties and the structural (size, molar mass, architecture, charge, density, structural arrangement of PC bilayers) as well as the thermodynamic (thermodynamic affinity for a solvent)parameters of the complexes. To measure these parameters we used a combination of the precise physico-chemical methods. They were the followings: a laser light scattering in static, dynamic and electrophoretic modes; an electron spin resonance spectroscopy; and an atomic force microscopy. The studied functional properties of the complexes included their water-solubility and protective ability against auto oxidation of the essential lipids encapsulated into the complexes.
