Determination of Chlorogenic Acids (CGA) in Coffee Beans using HPLC
Chlorogenic acids (CGA) are the main phenolic compounds in coffee and coffee has one of the highest concentrations of CGA of all plant constituents. In this study, the levels of CGA in certain coffee (Arabica Jimma (ArJM), Arabica Nekemit (ArNK), Arabica Sidamo (ArSD), Arabica Jimma (ArJM) raw, and Arabica Jimma (ArJM) Husk) brands found in Ethiopia were determined using High Performance Liquid...
متن کاملEffect of simultaneous consumption of milk and coffee on chlorogenic acids' bioavailability in humans.
Different studies have shown that milk may interact with polyphenols and affect their bioavailability in humans. The present study investigated the effect of the simultaneous consumption of coffee and milk on the urinary excretion of chlorogenic acids (CGA) and metabolites. Subjects were submitted to consumption of water, instant coffee (609 mmol of CGA) dissolved in water, and instant coffee d...
متن کاملFatty acids, essential amino acids, and chlorogenic acids profiles, in vitro protein digestibility and antioxidant activity of food products containing green coffee extract
The aim of this study was to determine the effect of addition of green coffee extract (GCE) in concentrations from 0.25 to 1 g 100 g-1 on the physical, sensory and chemical properties, and antioxidant activity of some food products. Two kinds of gnocchi (from fresh and dried potatoes), sponge cake, bread, mayonnaise, marshmallows, caramel candies and jellies were prepared. Among supplemented pr...
متن کاملImpact of dose on the bioavailability of coffee chlorogenic acids in humans.
Single servings of coffee beverage containing low (412 μmol), medium (635 μmol) and high (795 μmol) amounts of chlorogenic acids were administered to eleven healthy volunteers in a double-blind randomised controlled trial. Analysis of plasma and urine collected for 24 h revealed the presence of 12 metabolites in plasma and 16 metabolites in urine, principally in the form of sulphates, and to a ...
متن کاملA structural basis for the biosynthesis of the major chlorogenic acids found in coffee.
Chlorogenic acids (CGAs) are a group of phenolic secondary metabolites produced by certain plant species and an important component of coffee (Coffea spp.). The CGAs have been implicated in biotic and abiotic stress responses, while the related shikimate esters are key intermediates for lignin biosynthesis. Here, two hydroxycinnamoyl-coenzyme A shikimate/quinate hydroxycinnamoyl transferases (H...
