Gas chromatography-mass spectrometry method optimized using response surface modeling for the quantitation of fungal off-flavors in grapes and wine.

J. Agric. Food Chem. 63(11) , 2877-85, (2015)

An optimized method for the quantitation of volatile compounds responsible for off-aromas, such as earthy odors, found in wine and grapes was developed. The method involved a fast and simple headspace...

Entropic cost of protein-ligand binding and its dependence on the entropy in solution.

J. Phys. Chem. B 113(17) , 5871-84, (2009)

Two theoretical formulations are proposed and compared for the loss of translational and rotational entropy upon protein-ligand binding in water. The two theories share the same approach to evaluate t...

Occurrence of dissolved and particle-bound taste and odor compounds in Swiss lake waters.
