DETERMINATION OF ENCAPSULATED SEA BUCKTHORN OIL OXIDATION USING FTIR-ATR SPECTROSCOPY

This work examines the oxidation process of Sea buckthorn oil encapsulated in ionotropically cross-linked alginate beads under oxidative conditions. The oxidation of oil was monitored by Fourier Transform Infrared Spectroscopy equipped with the universal ATR (FTIR-ATR) as an internal accessory. We considered as markers of oxidation processes in sea buckthorn oil. the following ratios between absorbances of some important bands: A2853/A3005-3007. A2853/A1744. A2853/A1159-1160. A1744/A3005-3007. A1377/A3005-3007. A1159-1160/A3005-3007. The values of all ratios indicated a first stage oxidation of encapsulated oil and a second or third stage oxidation of free oil. The encapsulated Sea bucktorn oil showed a good stability under oxidation conditions. Differential scanning calorimetric analysis was used to characterize the thermal behavior of free oil. the oil alginate beads and empty beads.
