Abstract: | The aldehydes acetaldehyde, propanal, 2-methylpropanal, butanal, 3-methylbutanal, pentanal and hexanal, were reduced to their corresponding alcohols by incubation with strawberry fruit. The alcohols formed were then converted to their acetate, propionate, n-butyrate, isovalerate and n-caproate esters during the incubation with strawberry fruit. Simultaneous reaction of isobutyric acid, n-valeric acid and isocaproic acid with aldehyde and strawberry fruit resulted in the formation of esters of these acids. In all seven alcohols and 54 esters were produced by means of incubation of aldehydes and volatile fatty acids with strawberry fruit. |
