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.

Aminoalcohol Esters of Sorbic Acid*,†
Journal of the American Pharmaceutical Association (Scientific ed.), 1953Abstract A report is given of the preparation of three new esters of sorbic acid, diethylaminopropyl sorbate, 4‐morpholinoethyl sorbate, and piperidinoethyl sorbate, and of one previously reported ester, diethylaminoethyl sorbate.

Nucleophilic reactions of sorbic acid
Food Additives and Contaminants, 1990The conjugated dienoic acid structure of sorbic acid renders it susceptible to nucleophilic attack. Nucleophiles known to react with sorbic acid include sulphite ion and amines. These attack the molecule in position 5 and, in the cse of amines, cyclization to form substituted dihydropyridones may follow.

Sorbic acid (2,4-hexadienoic acid) and its salt, sorbate, have been used in the preservation of food products since the 1940s. While it can be isolated naturally from rowanberries (mountain ash tree), that used in foods is chemically synthesized. Sorbates have regulatory approval throughout the globe for application as antimicrobial preservatives for ...

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.

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 ...

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

Selective two-phase hydrogenation of sorbic acid using [Cp*Ru(sorbic acid)]+ catalyst
Reaction Kinetics and Catalysis Letters, 2006Unsaturated hexenoic acids are important compounds due to their utilization for specific aromatic alcohol (leaf alcohols) preparation. The influences of the reaction conditions on the sorbic acid hydrogenation to cis-hex-3-enoic acid are given. [Cp*Ru(sorbic acid)]CF3SO3 was used as a catalyst in two-phase hydrogenation.

Toxicology of sorbic acid and sorbates
Food Additives and Contaminants, 1990Sorbic acid and its salts have been subjected to an extensive battery of tests, including acute, short-term and chronic toxicity/carcinogenicity tests, two-generation reproduction and teratogenicity studies. These studies show that sorbic acid and sorbates have a very low level of mammalian toxicity, even in chronic studies at up to 10% of the diet ...

Enzymatic determination of sorbic acid
European Food Research and Technology, 2000An enzymatic method for the determination of sorbic acid based on the spectrophotometric measurement of sorbyl coenzyme A (sorbyl CoA) at 300 nm was developed. Sorbic acid is converted to sorbyl CoA with acyl CoA synthetase (EC 6.2.1.3) in the presence of coenzyme A and adenosine-5′-triphosphate.
