Red fruit oil (RFO) is a rapidly growing commodities which have comparatively high price than other oils. RFO was obtained through maceration process of red fruit using methanol as solvent followed by the partition using n-hexane and chloroform to obtain hexane fraction (HF) and chloroform fraction (CF). Antioxidant Butylated Hydroxytoluene (BHT) and -tocopherol of 200 mg.Kg- were added to both fraction respectively. RFOs was subjected at a 100 150 180 200 and 300C of heat temperature. These RFOs were further subjected to determination of peroxide value (PV) using titrimetric method and Atenuated (ATR-FTIR) spectrophotometry combined with chemometric multivariate calibration. Based on the optimization processes it can be shown that Attenuated Total Reflectance “Fourier Transformed Infra Red (ATR-FTIR) method combined with Partial Least Square (PLS) can be used for PV determination at 3085- 3610 cm- with R of 0.997 and standard error calibration of 0.14. This study indicates that ATR-FTIR spectroscopy can be used to determine PV. While the conventional method were time consuming in sample preparation ATR-FTIR spectroscopy is capable of determining PV accurately in less than 3 minutes for each sample it was simple and environmentally friendly.

Abstract

Red fruit oil (RFO) is a rapidly growing commodities which have comparatively high price than other oils. RFO was obtained through maceration process of red fruit using methanol as solvent followed by the partition using n-hexane and chloroform to obtain hexane fraction (HF) and chloroform fraction (CF). Antioxidant Butylated Hydroxytoluene (BHT) and -tocopherol of 200 mg.Kg- were added to both fraction respectively. RFOs was subjected at a 100 150 180 200 and 300C of heat temperature. These RFOs were further subjected to determination of peroxide value (PV) using titrimetric method and Atenuated (ATR-FTIR) spectrophotometry combined with chemometric multivariate calibration. Based on the optimization processes it can be shown that Attenuated Total Reflectance “Fourier Transformed Infra Red (ATR-FTIR) method combined with Partial Least Square (PLS) can be used for PV determination at 3085- 3610 cm- with R of 0.997 and standard error calibration of 0.14. This study indicates that ATR-FTIR spectroscopy can be used to determine PV. While the conventional method were time consuming in sample preparation ATR-FTIR spectroscopy is capable of determining PV accurately in less than 3 minutes for each sample it was simple and environmentally friendly.
