Abstract

The effect of some selected food preservatives on serum cholinesterase was determined. It was found that potassium metabisulphite, methyl parabene and propyl parabene caused a significant increase while sacharine, benzoic acid, salicylic acid, copper carbonate and sorbic acid caused a significant decrease in cholinesterase activity. The behavior of serum cholinesterase activity in response to a gradual change in the incubation time as well as the sorbic acid concentration was also studied. The graphical and statistical analysis of the data showed an exponential decrease in cholinesterase activity with an increase in the concentration of sorbic acid. The cholinesterase activity was also found to be decreased exponentially with an increase in the incubation time. The regression analysis showed a good agreement between the experimental and calculated values.
