Study of curcumin antioxidant activities in robust oil-water nanoemulsions

Abstract

Oil-in-water (o/w) nanoemulsions of peanut, linseed and mustard oils with sodium dodecyl sulphate (SDS), dodecyltrimethylammonium bromide (DTAB), tween 20 (Tw-20) and tween-40 (Tw-40), are prepared for catalysing antioxidant activity of curcumin. The peanut oil-Tw-20, linseed oil-DTAB and mustard oil-SDS of (488.41 to 1337.09), (446.10 to 1124.00) and (27.37 to 62.05) nm sizes, have expressed (72.38 to 93.13), (65.08 to 85.55) and (62.15 to 89.44)%DPPH free radical scavenging activities (FRSA). Their surface tension and viscosities, within (41.68-58.77) mN/m and (0.8051-1.4059) mPa-s respectively show better curcumin dispersion. FTIR stretching frequencies (SF) of (1500-2000) cm-1(>C=O) and 3500cm-1 (-OH) have inferred a curcumin encapsulation with a disappearance of oil-curcumin (500-1300) cm-1 SF. Friccohesity as distributing indicator exercised via cohesive forces (CFs) and intermolecular forces (IMFs) has depicted a curcumin nanodispersion on weakened oil and curc CFs.
