Abstract

U ovom radu provedeno je kapsuliranje eteričnog ulja smilja i prirodnog bojila životinjskog podrijetla (košenila) tehnikom isparavanja otapala. Analiza ulja smilja, bojila i sintetiziranih kapsula provedena je UV/VIS spektrofotometrijskom analizom na apsorpcijskom spektrofotometru Cary 50 Solascreen. Sintetizirane kapsule dodatno su analizirane skenirajućim elektronskim mikroskopom (SEM analiza). Bojadisane sintetizirane mikrokapsule, bojilom životinjskog podrijetla (košenil), dodatno su promatrane s Dino-Lite digitalnim mikroskopom. Apsorpcijskim spektrofotometrom potvrđena je prisutnost eteričnog ulja smilja u sintetiziranim mikrokapsulama te pomoću baždarnog dijagrama izračunata je točna koncentracija ulja smilja u sintetiziranim mikrokapsulama.

Abstract (english)

In this paper, encapsulation of immortelle's essential oil and animal origin natural dye (cochineal) was carried out by the solvent evaporation technique. Analysis of immortelle's oil, dye and synthesized capsules was performed by UV/VIS spectrophotometric analysis on absorption spectrophotometer Cary 50 Solascreen. The synthesized capsules were additionally analyzed by scanning electron microscope (SEM analysis). The dyed synthesized microcapsules with animal origin natural dye (cochineal), were additionally observed with a Dino-Lite digital microscope. Using the calibration diagram, unknown concentrations of synthesized microcapsules were calculated. The absorption spectrophotometer confirmed the presence of immortelle's essential oil in synthesized microcapsules.
