Rice Bran Oil Extraction with Supercritical Fluid (sfe) to Obtain Enriched Tocopherols and Tocotrienols Fractions
Parboiled rice bran oil was obtained using supercritical CO2 under different conditions of temperature (2°C to 40°C) and pressure (25 to 200 bar). In this study the experiments were carried out with two separators coupled to the extractor. The temperature levels in the first separator were 25°C and 40°C and in the second it was maintained constant at 2°C. The pressures in the first separator we...
متن کاملChromatographic analyses of tocopherols and tocotrienols in palm oil.
Analyses of tocols (tocopherols and tocotrienols) in palm oil have been extensively reported in the past. However, due to the scarcity of individual tocotrienol standards, calibrations have mostly been carried out using only α-tocopherol as standard. Moreover, even if the individual tocotrienols are being used, their reliability is often questioned, because tocotrienols are highly susceptible t...
متن کاملRice bran oil solvent extraction process pdf
Oil is obtained from rice bran, by the process of extraction with petroleum solvents, whereas the edible grade oil is the one refined by neutralisation with alkali.
متن کاملDegradation of tocopherols in rice bran oil submitted to heating at different temperatures.
The objective of this study has been to evaluate the stability of alpha-, (gamma+beta)-, and delta-tocopherols in rice bran oil chemically refined submitted to heating in a heater without air circulation and shielded from light, at temperatures of 100 degrees C and 180 degrees C. The collection of samples took place after 48, 96, 144, 192, 240, 336, and 432 h of heating and were stored in amber...
متن کاملQualitative and Quantitative Evaluation of Tocopherols and Phytosterols in Soybean Oil Distillate
Soyabean might be considered as the most popular oil seed crop in the world and the extracted oil has gained it is popularity due to it is application in formulated food products as well as by itself as oil or hardened form as frying or cooking media. Soyabean oil has been subjected to various refining stages in particular deodorisation where different classes of compounds are collected in the ...
