- the extract according to the invention from by-products of the processing of nuts and legumes can stabilize anthocyanins and / or anthocyanidins.
- the extract according to the invention can stabilize the anthocyanins and / or anthocyanidins against decomposition under the influence of light.
- Anthocyanins are a group of chemically related blue, violet and red dyes (benzopyrylium salts) which are very common in the plant world and which are dissolved in the pulp of flowers and fruits and occasionally also in the shoot axes and leaves of plants and which give rise to their characteristic colorings . From a chemical point of view, anthocyanins are glycosides of the actual chromophores, the anthocyanidins. All known anthocyanidins have the basic structure of C-4 'hydroxylated 2-phenylchromene (shown in the primary structure as a flavylium cation):
- the anthocyanidins are derived from three basic structures, the pelargonidine, cyanidine and delphinidine, which differ from one another in their different substitution in the B ring. 3-Deoxyanthocyanidins are also known (see, for example, Römpp Lexikon Chemie, 10th edition 1996-1999, pp. 210-212).
- anthocyanidins found in many different plants and parts of plants include pelargonidine, cyanidine, delphinidine, apigenin, paeonidine, petunidine, malvidin, hirsutidine and tuberidine.
