摘要

The present work is focused on the elucidation of the role of both the plant antioxidant (an essential oil of clove, EO) and the covalent conjugate (sodium caseinate (SC) + maltodextrin (SA2, dextrose equivalent, DE = 2), the weight ratio of SA2 to SC equals to 2 : 1) in the protection of the polyunsaturated lipids (phosphatidylcholine (PC) in a combination with either triglycerides of a flaxseed oil (FO) or an α-linolenic acid (ALA)), against oxidation. The inhibitor action of the plant antioxidant was estimated by capillary gas-liquid chromatography (GLC). The synergetic stabilizing effect of the plant antioxidant and the covalent conjugate was found. From the biopolymer side, the governing role in this stabilizing effect of the extent of the co-assembly of the conjugate with the polyunsaturated lipids into the complex particles, the density and the architecture of the latter in line with the increase in the microviscosity of the bilayers of the mixed PC liposomes involved, was suggested on the strength of the combined data of the static (SLS) and dynamic (DLS) multiangle laser light scattering, atomic-force microscopy (AFM), and electron paramagnetic resonance spectroscopy (EPRS).
