| Abstract | ?-Oryzanolis a natural bioactive component found in rice bran oil. Quantitative analysis of the compound is usually doneby UV-spectrophotometricor chromatographicmethods.Thisstudyevaluatedthe potential of near infrared spectroscopy (NIRS) transmission analysis for determining?-oryzanolin commercial rice bran oilusing standard ?-oryzanolin 3 different solvent systems, i.e.in hexane, in purified medium chain fatty acids (MCF), and in hexane containing 10% MCF. The results showed that NIRS analysis using standard ?-oryzanolin hexane allowed estimation of?-oryzanolcontent in commercial rice bran oilwith higheraccuracythan the others. The predictedperformance of the developed model measured by the ratio of performance to deviation (RPD) was5.93, which indicated that the method effectively provided an alternative for determination of ?-oryzanolin rice bran oil. |
