Abstract
Summary
In this study, microencapsulation was used on gurum seed oil (GSO) to evaluate quality characteristics during accelerated storage at 60°C for 28 days. Accelerated storage altered the levels of all fatty acids of GSO (31.36–95.65%), whereas, those of microencapsulated GSO showed reduced changes (0.13–38.46%). At the beginning of storage, the tocopherol and phytosterol content of GSO (563.61 and 149.86 mg/100 g oil, respectively) was significantly higher than that of MGSO (425.30 and 132.21 mg/100 g oil, respectively), while the polyphenol contents of GSO and MGSO were 20.21 mg GAE/kg oil and 19.45 mg GAE/kg oil, respectively. The IC50% DPPH antiradical activity of GSO and MGSO was 20.89 and 19.31 mg/mL, respectively, which was increased for GSO and remained constant for MGSO during accelerated storage. In conclusion, microencapsulation effectively preserved the quality of GSO during accelerated storage at 60°C for up to 28 days.
