Effect of nano materials on lutein extraction from collard using ethanol assisted with ultrasonic
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 7
Abstract
In the process of extracting lutein from collard using 95% ethanol assisted with ultrasonic, the effects of nano silicon dioxide, hydrophilic nano titanium dioxide and lipophilic nano titanium dioxide on the lutein yield of collard were investigated. The result showed that lipophilic nano titanium dioxide might significantly increase lutein yield. When the collard was extracted with 95% ethanol for 30 minutes, the lutein yield was 9.24 mg/100g under 700 W ultrasonic power through sample to solvent ratio 1:15 at 65 ℃ with the addition of lipophilic nano titanium dioxide of 5mg/15mL 95% ethanol. Keywords: lutein, collard, nano materials, ultrasonic, ethanol.
