Electrophoretic mobility of Tween 80-encapsulated agarwood oil in aqueous


Boon, Yih Tien and Naim, Mohd Nazli and Zakaria, Rabitah and Abu Bakar, Noor Fitrah and Ahmad, Noraini (2016) Electrophoretic mobility of Tween 80-encapsulated agarwood oil in aqueous. International Food Research Journal, 23 (suppl.). S133-S140. ISSN 1985-4668; ESSN: 2231-7546


A study on the feasibility of using gel electrophoresis technique in grading the agarwood oil quality was investigated. Prior to electrophoresis, the emulsified agarwood oil droplets were screened by a diffuse layer of ions that have equal absolute charge to that of the droplets surface charge in aqueous phase. The condition was obtained by varying the concentrations of non-ionic surfactant; Tween 80 until the critical aggregation concentration (CAC) value of 0.0167% (v/v) was achieved. The prepared droplets suspended in the aqueous within nano-metre size and had ability to migrate through the agarose gel with its own specific electrophoretic mobility. However, due to the limitation of gel pore size, only large oil droplets (>200 nm) indicated visible bands. Overall, a novel work for grading the emulsified agarwood oil droplet with its own electrical properties was feasible.
