  One aspect of the present invention is concerned with a composition that can suitably be used as an additive in beverages and foodstuffs, which composition: i. contains at least 0.5%, preferably at least 1.0%, by weight of dry matter, of pyrazine derivatives according to formula (I): wherein R 1 -R 4 independently represent hydrogen; a hydroxyhydrocarbyl residue; an ester of a hydroxyhydrocarbyl residue; or an ether of a hydroxyhydrocarbyl residue; and at least one R 1 -R 4 is a hydroxyhydrocarbyl residue or an ester or an ether thereof, and ii. exhibits an absorption ratio A 280/560 of at least 80, preferably of at least 250. The invention also relates to a method of manufacturing a beverage or a foodstuff that is resistant to light induced flavour changes, said method comprising introducing into said beverage or foodstuff the aforementioned light stabilising composition and to a process for the manufacture of such a light stabilising composition.
