Quencher of electronically excited state

Therefore, it is a very relevant issue the evaluation of molecules and macromolecules that can efficiently act as quenchers of electronically excited states, such as 3RF and 1O2 as examples, to avoid the formation of ROS and/or eliminate them (Wondrak et al., 2006). 

These results show the functional ability of GA to act as quencher of electronically excited states in food systems either as non-processed gum or spray-drying microencapsulated preparations. 

Oxygen as a Quencher Molecular oxygen is an efficient quencher of electronically excited states of inorganic complexes and organic molecules. The quenching of Ru(bpy)32+ by molecular oxygen is believed to occur via electron transfer pathway while that of Cr(bpy)33+ occurs via energy transfer ...
