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‐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.

ChemInform Abstract: Dimerization of Sorbic Acid.
ChemInform, 1989AbstractDimerization of sorbic acid (I) followed by esterification or of sorbic acid methyl ester (III) with or without montmorillonite as catalyst leads to the cyclohexenes (IVa)‐(Vd).

The use of sorbic acid in salted fish
International Journal of Food Science & Technology, 1969Summary. It has been shown that the development of Hemispora stellata Vuill and red halophilic bacteria in salted snoek (Thyrsites atun Euph.) can be combated successfully by the use of sorbic acid during salting of the fish. Applications of sorbic acid by dipping of the fish in salt‐sorbate solutions proved to be more effective than the use of a ...

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.

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 ...

Kinetics of the reaction of sorbic acid with sulphite species
Food Additives and Contaminants, 1992Under aerobic conditions, the reaction of sorbic acid with sulphite species, S(IV), involves a pH-dependent oxidative mechanism with the loss of S(IV). Sorbic acid is essential to the process. In the absence of air, a much slower nucleophilic addition of sulphite ion to undissociated sorbic acid takes place.

Toxicology Letters, 1988
The in vivo induction of sister chromatid exchanges and micronuclei formations by acute treatment with different concentrations of sorbic acid and by nitrite, individually and in combination, was studied in bone marrow cells of mice. A significant increase in the frequency of sister chromatid exchanges was only observed with the three higher ...
