| Abstract: | The present paper introduced a rapid gas chromatographic method for the detenmination of the food preservatie-dehydroacetic acid in the cheese and strawberry. Sample preparation procedures and conditions for determination were determined. The degradation of dehydroacetic acid wae examined by determining DHA concentration in the cheese sample, at different in tervals of storage. |
