설명

일반 설명

Potassium sorbate is potassium salt of sorbic acid. Qualitative and quantitative estimation of potassium sorbate in foods and beverages by high-performance liquid chromatography (HPLC) followed by UV diode array detection (HPLC-UV) and LC-MS/MS (Liquid chromatography-mass spectrometry) have been proposed. Potassium sorbate is widely used in the food and beverage industry as a preservative against microbial growth.

애플리케이션

• Potassium sorbate reduces production of ethanol and 2 esters in corn silage: This study explores the effects of potassium sorbate on ethanol production and volatile organic compounds in corn silage, which can influence the nutritional quality and safety of the feed (SD Hafner, RB Franco, L Kung Jr, CA Rotz, 2014 - Elsevier).


• Copper corrosion mitigation by binary inhibitor compositions of potassium sorbate and benzotriazole: Research into how potassium sorbate can be used in combination with benzotriazole to mitigate copper corrosion, which has implications in material preservation and engineering (D Gelman, D Starosvetsky, Y Ein-Eli, 2014 - Elsevier).
