Sorbic acid‐amine function interactions
Food Additives and Contaminants, 1998Sorbic acid has a system of conjugated double bonds which makes it able to undergo nucleophilic addition reactions with certain functions. The interactions between sorbic acid and amine functions present in the endogenous constituents of food were quantified.

Pressure induced transformations in sorbic acid
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2017This research reports a pressure dependent Raman study of the sorbic acid between 0.0 and 10.0GPa. The unpolarized Raman spectra were measured in the spectral range of 20-3000cm-1. The high-pressure Raman scattering study of the sorbic acid showed that it underwent a gradual, disordering process.

Determination of sorbic acid with sodium chlorite
Talanta, 1967A new method for the determination of sorbic acid is proposed, using sodium chlorite in hydrochloric add medium as reagent. In these conditions the hydrochloric acid is oxidized to chlorine which adds on to the double bonds of the sorbic acid. The addition is rapid (30-90 sec) and for this reason the determination is more rapid then others similar to ...

Interaction of Sorbic Acid with an Insoluble Polyamide
Journal of Pharmaceutical Sciences, 1964Specially treated nylon 66 strips were exposed to sorbic acid solutions at a number of different concentrations and at several temperatures and the quantity of drug sorbed determined by suitable means. Thermodynamic and kinetic treatment of the data permitted the evaluation of a number of constants such as ( a ) saturation value of drug in the plastic,

Sorbic acid resistance: the inoculum effect
Yeast, 2000Zygosaccharomyces is a genus associated with the more extreme spoilage yeasts. Zygosaccharomyces spoilage yeasts are osmotolerant, fructophiles (preferring fructose), highly-fermentative and extremely preservative-resistant. Zygosaccharomyces bailii can grow in the presence of commonly-used food preservatives, benzoic, acetic or sorbic acids, at ...

Spectrophotometric estimation of benzoic and sorbic acids
Journal of the Science of Food and Agriculture, 1975AbstractA spectrophotometric method is described for estimations of benzoic and sorbic acids in materials with background absorption in the ultraviolet region. The estimation can be done when both preservatives are present in equal or nonequal ratios. The coefficients of variation (average standard deviation) are 0.23–1.98% for benzoic acid and 0.40–1 ...

Improved method for the estimation of parasorbic acid in sorbic acid
Journal of the Science of Food and Agriculture, 1973AbstractA simple method for determining parasorbic acid (I) in sorbic acid (II), suitable for use down to levels of 0.5 mg/kg, is described. The parasorbic acid is extracted from aqueous potassium sorbate with dichloromethane and determined by gas chromatography using a flame ionisation detector.

Journal of the American Optometric Association, 1986
135 patients wearing hydrogel lenses were prescribed a care system of sorbic acid preserved surfactant, Lensept and Bausch and Lomb Sensitive Eyes Saline (sorbic acid 0.10%). Fifteen percent of patients presented with an adverse ocular response to their care system. The etiology was attributed to sorbic acid as the use of nonpreserved saline eliminated

Sorbic Acid, Benzoic Acid, and Dimethyldicarbonate
1995Sorbic acid is a short-chained unsaturated fatty acid widely used in the wine and food industry as a chemical preservative. Because sorbic acid is not readily soluble, it is usually sold as the soluble salt, potassium sorbate. Effective primarily as a fungistat, sorbic acid is added to sweet wines.
