Validation of a HPLC Method for the Determination of Benzoic Acid and Sorbic Acid in Noodles
A simple, sensitive and specific HPLC method was validated for the simultaneous determination of benzoic acid and sorbic acid in noodles. Sample preparation involved the extraction with methanol and water (60:40, v/v). The separation was achieved on a GerminiC18 modified silica column (50 mm x 4.6 mm i.d., 5 μm particle diameter). The mobile phase consisted of 0.05 M ammonium acetate (pH 4.4) a...
متن کاملSpectrophotometric Flow- Injection Method for Determination of Sorbic Acid in Wines
A simple, rapid, and accurate spectrophotometric flow-injection method was developed for the determination of sorbic acid in wines based on the oxidation of sorbic acid with K2Cr2O7/H2SO4 at 1008C, followed by reaction of the resulting malonaldehyde with thiobarbituric acid, also at 1008C, to give a red product, the absorbance of which is measured at 532 nm. The method requires no prior distill...
