Organic acids and esters

Witryna2 lip 2024 · Physical properties of Esters. Lower carboxylic esters are colorless liquids with distinctive fruity odors. Esters are insoluble in water but soluble in organic solvents. The boiling point of methyl ethyl esters is significantly lower than that of parent acid. In the IR spectrum ester shows the characteristic -C=O stretching frequency at 1735 cm-1. Witryna4 maj 2024 · It is well known that organic acids (OAs) could affect the flavour of fruit juices and beverages. However, the molecular mechanism of aroma release is still unclear. In this study, the effects of citric acid (CA), L-(-)-malic acid (MA) and L-lactic acid (LA) on the release of six selected esters and their sensory perception were …
