General description

Formic acid is one of the main volatile flavor compounds in black tea. It is also one of the main odor-active compounds in acid-hydrolyzed soy sauce.

Application


  • Quantitative Analysis of Residual Butylated Hydroxytoluene and Butylated Hydroxyanisole in Salmo Salar, Milk, and Butter by Liquid Chromatography-Tandem Mass Spectrometry.: In this study, formic acid is used in the preparation of samples for liquid chromatography-tandem mass spectrometry analysis. The research focuses on the detection and quantification of antioxidant residues in food products, contributing to food safety and quality control protocols (Galal et al., 2024).
