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 ...

Effects of sorbic acid and sorbic acid-nitrite in vivo on bone marrow chromosomes of mice
Toxicology Letters, 1986The effect of sorbic acid alone and in combination with sodium nitrite has been studied on bone marrow chromosomes of mice following 30 days oral treatment. Bone marrow of mice exposed to sorbic acid (15 mg/kg) and sorbic acid nitrite (7.5-1 mg/kg) showed an increase in mitotic index indicating that the drugs had an effect on spindle apparatus.

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.

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.

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 ...

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 ...

Sorbic acid-induced erythema and edema
Journal of the American Academy of Dermatology, 1986Sorbic acid concentrations as low as 0.1% produced transient erythema with edema and flare after open or closed application to human skin. Multiple areas of the body were tested. Reactions were most intense on the face but also could be produced on the back, forearm, and deltoid areas.

Selective two-phase hydrogenation of sorbic acid using [Cp*Ru(sorbic acid)]+ catalyst [PDF]
Reaction Kinetics and Catalysis Letters, 2006 Unsaturated 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.

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.

Notes on selectivity aspects in sorbic acid and sorbic alcohol hydrogenation
Research on Chemical Intermediates, 2009Sorbic acid and sorbic alcohol hydrogenations to the cis-hex-3-enoic acid or cis-hex-3-en-1-ol were carried out at the same conditions in three different systems—homogeneous, two-phase and heterogeneous. The complex [Cp*Ru(sorbic acid)]CF3SO3 was used as a catalyst. Selectivity and reactivity of both the compounds varied significantly.
