UJI STABILITAS DAN AKTIVITAS ANTIOKSIDAN MIKROEMULSI LIKOPEN TOMAT(Solanum lycopersicum L.)
Abstract: Lycopene is a class
of keratonoid that have been proven has antioxidant activity but has limited
solubility in water. So as to boost their solubility, in this study conducted
in the form of microemulsion formulations. This study aims to get a tomato
lycopene extract microemulsion which is stable and has antioxidant effects. The
research was initiated to test the antioxidant power of tomato lycopene extract
in vitro against DPPH. Tomato lycopene extract microemulsion is formulated
based on the optimization of the composition of the base consisting of the VCO
as the oil phase, tween 80 as surfactant and glycerin as cosurfactant.
Preparations produced were tested for antioxidant activity and their physical
and chemical stability testing which include: organoleptic, viscosity, globule
size and pH during 28 days of storage. The results showed that tomato lycopene
extract formula microemulsion stable composition of tomato lycopene extract
0.3%, VCO 15%, tween 80% and 35% glycerin. The test results obtained physical
stability of the microemulsion formula elected tomato lycopene extract has a
distinctive scent of aromatic, orange, thick, globule size of <5 μm, viscosity
(600, 33 ± 69.29 to 746 cPs ± 8.32), and pH ( 6.27 ± 0.20 to 6.79 ± 0.10). As
very strong antioxidant activity with IC50 value of 29.07 ppm.
