Centrifuge at 1000 g for 10 min. If a gel forms in the upper organic layer, add 2 mL water-saturated n-butanol and gently stir into the upper layer, with a glass rod, until emulsion breaks. Transfer upper organic layer to a 25 mL volumetric flask using a Pasteur pipette. Repeat the extraction procedure with three further 5 mL portions of watersaturated n-butanol. Make the combined n-butanol extracts up to 25 mL with water-saturated n-butanol. Accurately dilute an aliquot of the filtrate with an equal volume of mobile phase (1L + 1L dilution of mobile phase A and solution B).

Inject duplicate 1 µL portions of standard solutions into gas chromatograph. Use same conditions as for test portion solution. Measure peak heights and calculate peak height ratios of sorbic acid/caproic acid. Peak height ratios for duplicate injections should differ <5 %. Plot weight ratios (x) vs. average peak height ratios (y) for each preservative. Calculate slope and intercept of standard curve by method of least squares. 1] where b = slope of standard curve a = intercept y = average peak height ratio of preservative/internal standard W = weight of test portion in g W′ = weight of internal standard in mg.
