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 کاملSimultaneous determination of preservatives (benzoic acid, sorbic acid, methylparaben and propylparaben) in foodstuffs using high-performance liquid chromatography.
A reversed-phased HPLC method that allows the separation and simultaneous determination of the preservatives benzoic (BA) and sorbic acids (SA), methyl- (MP) and propylparabens (PP) is described. The separations were effected by using an initial mobile phase of methanol-acetate buffer (pH 4.4) (35:65) to elute BA, SA and MP and changing the mobile phase composition to methanol-acetate buffer (p...
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...
متن کاملFerrous Iron Oxidation by Thiobacillus ferrooxidans: Inhibition with Benzoic Acid, Sorbic Acid, and Sodium Lauryl Sulfate.
Benzoic acid, sorbic acid, and sodium lauryl sulfate at low concentrations (5 to 10 mg/liter) each effectively inhibited bacterial oxidation of ferrous iron in batch cultures of Thiobacillus ferrooxidans. The rate of chemical oxidation of ferrous iron in low-pH, sterile batch reactors was not substantially affected at the tested concentrations (5 to 50 mg/liter) of any of the compounds.
متن کاملAnalysis of benzoic acid and sorbic acid in Thai rice wines and distillates by solid-phase sorbent extraction and high-performance liquid chromatography
An application of solid-phase extraction (SPE) for high-performance liquid chromatography (HPLC) analysis was developed for the rapid determination of benzoic acid and sorbic acid in Thai rice wine and distillate products. The SPE extraction gave promising results with 95.7+1.7% recovery for benzoic acid standard, and 95.2+2.3% for sorbic acid standard. Mean relative standard deviation (RSD) fo...
