Inhibition of sulfhydryl enzymes with sorbic acid



Inhibition of sulfhydryl enzymes with sorbic acid



Food Res 24(1): 37-43



Sorbic acid was an inhibitor of the sulfhydryl enzymes, ficin and alcohol dehydrogenase, at concentrations of 10-4 [image] and was more efficient as an inhibitor than was maleic acid. Aldolase and urease were not significantly inhibited by sorbic and maleic acids under the conditions used. UV-irradiated sorbic acid was a better inhibitor of ficin than was sorbic acid. It is suggested that the mechanism of inhibition of sulfhydryl enzymes by sorbic acid and similar [alpha],[beta]-unsaturated acids is its mode of inhibition of the growth and reproduction of microorganisms.
