Abstract


The sunflower oil require of an extraction process that reduce the amount of impurities, and the use of a solvent that has not implications over the environment. An alternative is the use of the isopropyl alcohol. In this work was studied the extraction conditions of two experimental varieties of sunflower Madero-91 and Cianoc-2, the controls were hexane and Sunflower seed variety Victoria. It was found differences on the physical characteristics and in the dispersion of the physical measures from the three varieties used. The percent yield of crude oil extracted with isopropyl alcohol was not different of the obtained with hexane. The level of free fatty acids was higher in the oils extracted with isopropyl alcohol than the oils extracted with hexane, no differences was found in the amount of malonic aldehide.
