Since the nutrition value of rice is diminished during rice processing, technology that can preserve and sustain functional compounds is necessary. In this study, supercritical carbon dioxide (SC-CO 2 ) extraction was optimized for operational conditions (time, temperature, pressure and modifier) to extract Vitamin E, γ-oryzanols and xanthophylls from rice bran. The simultaneous quantification of the compounds was developed using high-performance liquid chromatography with diode array and fluorescence detectors. Central composite design and respond surface methodology were applied to achieve optimum extraction conditions. The optimized conditions were 60 min, 43 °C, 5420 psi with 10% ethanol as a modifier. Pigmented rice bran extracts contained greater amounts of functional phytochemicals than non-pigmented rice bran extracts (0.68, 1410, and non-detectable μg/g compared with 16.65, 2480, and 0.10 μg/g of Vitamin E, γ-oryzanols and xanthophylls in pigmented and non-pigmented ones, respectively). SC-CO 2 extraction with modifier would be p romising for preparation of phytochemical essences for therapeutic purpose. 2017-09-28T04:20:41Z 2017-09-28T04:20:41Z 2016-11-15 Journal 03088146 2-s2.0-84966429559 10.1016/j.foodchem.2016.05.001 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84966429559&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/41343
