p-Coumaric acid abatement by ozone in aqueous solution

Water Research, 1995
Abstract The ozonation process of p-coumaric acid in aqueous solution is studied by identification and quantitative evaluation of intermediates and final oxidation products. In all the investigated pH range (2.0–8.0) the initial oxidation step is represented by the direct attack of ozone to the exocyclic double bond, following oxidation steps being ...

Synthesis and properties of coumaric acid derivative homo-polymers

Journal of Biomaterials Science, Polymer Edition, 2008
Poly(4-hydroxycinnamic acid) (P4HCA), poly(3-hydroxycinnamic acid) (P3HCA), poly(3-methoxy-4-hydroxycinnamic acid) (PMHCA) and poly(3,4-dihydroxycinnamic acid) (PDHCA) were synthesized by the thermal poly-condensation of the corresponding monomers, which are lignin precursors, coumaric acid derivatives consisting of cinnamoyl groups and different ...

Dietary caffeic acid, ferulic acid and coumaric acid supplements on cholesterol metabolism and antioxidant activity in rats

, 2020
This study was designed to test the lipid-lowering and antioxidative activities of three phenolic compounds, caffeic acid, ferulic acid and coumaric acid. Four groups of rats were given a semisynthetic diet containing 3% of cholesterol for 6 weeks.

Novel multi-phase nano-emulsion preparation for co-loading hydrophilic arbutin and hydrophobic coumaric acid using hydrocolloids

Food Hydrocolloids, 2019
This study was designed to co-load hydrophilic arbutin and hydrophobic coumaric acid in nano-sized multi-phase emulsion (W/O/W) using hydrocolloids and examined for its various stability and bioaccessibility parameters. The creaming stability and sensory

Fluorometric determination of p-coumaric acid in beer

Journal of Agricultural and Food Chemistry, 1988
A new spectrofluorometric method to determine p-coumaric acid in beer has been developed. After the pH of the samples was adjusted to 2, impurities were extracted into hexane. Phenolics were then extracted into ethyl acetate, dried, and redissolved in water.

Lipophilization and molecular encapsulation of p-coumaric acid by amylose inclusion complex

Food Hydrocolloids, 2019
p-Coumaric acid (CA) is a natural phenolic compound with a wide range of bioactivities, but its tendency to degrade during food processing and storage limits its application in functional foods.

Retention of coumaric acid by soil and its colloidal components

Water, Air, and Soil Pollution, 1990
In this study of the behavior of coumaric acid added to soil, the disappearance of the acid was found to be due to adsorption plus microbial degradation, and was influenced by the concentration and contact time. Adsorption experiments set up with soils varying widely in their chemical and physical properties, showed that the Freundlich isotherm fits ...

Optimisation of coumaric acid production from aromatic amino acids in Kluyveromyces marxianus

Journal of Biotechnology
Yeasts are attractive hosts for the production of heterologous products due to their genetic tractability and relative ease of growth. While the baker's yeast Saccharomyces cerevisiae is a powerful workhorse of the biotechnology industry, the species has metabolic limitations and it is critical that we develop alternative platforms that will facilitate
