Production of hexanal from hydrolyzed sunflower oil by lipoxygenase and hydroperoxid lyase enzymes

Hexanal was produced from hydrolyzed sunflower oil in two steps: 1) 13-hydroperoxy-9-( Z ),11( E )-octadecadienoic acid (13-HPOD) was formed from linoleic acid (100 mM) by soybean lipoxygenase-1 isoenzyme (Lox-1) with O 2 , the reaction resulted 68.7 mM 13-HPOD with a yield of 72%. 2) 13-HPOD (15 mM) was cleaved by spinach leaf hydroperoxide lyase resulting 8.2 mM hexanal (54% yield). Hexanal was isolated from the reaction mixture by repeated steam distillation.
