PCT No. PCT/EP93/01057 Sec. 371 Date Jan. 21, 1994 Sec. 102(e) Date Jan. 21, 1994 PCT Filed May 3, 1993 PCT Pub. No. WO93/24644 PCT Pub. Date Dec. 9, 1993.The aldehydes, N-hexanal, 3-(Z)-hexen-1-al and 2-(E)-hexen-1-al, and their corresponding alcohols are enzymatically produced in high yield from linoleic, linolenic acid or a natural precursor thereof such as hydrolyzed oil. The acid or natural precursor is mixed with soy flour containing lipoxygenase which converts the acid to 13-hydroperoxy-octadeca-9,11-dienoic acid or 13-hydroperoxy-octadeca-9,11,15-trienoic acid. Guava homogenate containing lyase is added to convert the 13-hydroperoxy-octadeca-9,11-dienoic acid into n-hexanal or the 13-hydroperoxy-octadeca-9,11,15-trienoic acid into 3-(Z)-hexen-1-al. The n-hexanal or 3-(Z)-hexen-1-al is recovered, or reduced with yeast to n-hexanol or 3-(Z)-hexen-1-ol, respectively. Alternatively, the 3-(Z)-hexen-1-al is isomerized to obtain 2-(E)-hexen-1-al which is recovered or reduced with yeast to 2-(E)-hexen-1-ol which is recovered. The yeast used for reducing and isomerizing is Saccharomyces cerevisiae. Steam distillation and/or extraction with an inert organic solvent is used in recovery of the aldehydes and alcohols. |
