Fungal metabolites of sorbic acid

Food Additives and Contaminants, 1990
A number of fungal detoxification reactions of sorbic acid have been reviewed. These include decarboxylation to give trans-1,3-pentadiene, esterification to give ethyl sorbate, reduction to give 4-hexenol and 4-hexenoic acid. It was shown that seven Penicillium species could convert sorbic acid into 1,3-pentadiene whilst P. bilaii, P. fellutanum and P.

Effects of sorbic acid and sorbic acid-nitrite in vivo on bone marrow chromosomes of mice

Toxicology Letters, 1986
The 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.

Notes on selectivity aspects in sorbic acid and sorbic alcohol hydrogenation

Research on Chemical Intermediates, 2009
Sorbic 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.

Nucleophilic reactions of sorbic acid

Food Additives and Contaminants, 1990
The 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.

Aminoalcohol Esters of Sorbic Acid*,†

Journal of the American Pharmaceutical Association (Scientific ed.), 1953
Abstract 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.

Sorbic Acid and Sorbates

2020
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 ...

Toxicology of sorbic acid and sorbates

Food Additives and Contaminants, 1990
Sorbic 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 ...
