General description
Sorbates have been reported to be less toxic than benzoate and have been classified as “Generally Recognized as Safe” (GRAS) additives by the U.S. Food and Drug Administration (FDA).Sorbic acid is metabolised to mainly to carbon dioxide. While the minor amounts are converted to trans,trans-muconic acid (ttMA), which is excreted unchanged into the urine. Urinary ttMA is a biomarker for the occupational and environmental exposure to benzene. Ability of trans,trans-2,4-Hexadienoic acid potassium salt (Sorbic acid potassium salt, Potassium sorbate) to induce chromosome aberrations, sister chromatid exchanges (SCE) and gene mutations in cultured Chinese hamster V79 cells has been examined.Potassium sorbate is reported to be less genotoxic than the sodium salt analog.
Application
- Determination of preservatives in canned food products: Investigates the presence of preservatives, including trans,trans-2,4-Hexadienoic acid potassium salt, in canned foods (AM Charles, 2014).
- The effect of selected preservatives on the growth of Listeria monocytogenes in ready-to-eat foods: Examines the inhibitory effects of potassium sorbate (trans-2,4-hexadienoic acid potassium salt) on Listeria monocytogenes (L Necidová, B Mrňousová, D Haruštiaková, Š Bursová, 2019).
- Effect of leave‐on cosmetic antimicrobial preservatives on healthy skin resident Staphylococcus epidermidis: Evaluates the impact of various preservatives, including trans,trans-2,4-Hexadienoic acid potassium salt, on skin microbiota (W Zhang, X Wang, L Zhao, Y Gu, 2023).
- Catalytic Strategy for Conversion of Triacetic Acid Lactone to Potassium Sorbate: Describes a method for synthesizing potassium sorbate from triacetic acid lactone using a catalytic process (MS Kim, D Choi, J Ha, K Choi, JH Yu, JA Dumesic, 2023).

Sorbic acid reacts with nitrite to yield mutagenic products such as 1,4-dinitro-2-methylpyrrole (NMP) and ethylnitrolic acid (ENA). In order to know the stability of these compounds, a kinetic study of their decomposition reactions was performed in the 6.0-9.5 pH range.
