Comparison of isopropanol and hexane for extraction of vitamin E and oryzanols from stabilized rice bran
The effects of solvent‐to‐bran ratio (2∶1 and 3∶1, w/w), extraction temperature (40 and 60°C), and time (5, 10, 15, 20, and 30 min) were studied for hexane and isopropanol extraction. Increasing the solvent‐to‐bran ratios and extraction temperature increased the amounts of crude oil, vitamin E and o...

Increasing the solvent‐to‐bran ratios and extraction temperature increased the amounts of crude oil, vitamin E and oryzanol recovered for both solvents. An extraction time of 15 min was sufficient for optimum crude oil, vitamin E, and oryzanol extraction. Preheated isopropanol (3∶1 solvent/bran ratio and 60°C) extracted less crude oil (P |
