"High nitrogen content" basically means food high in proteins and/or free amino acids (which are the building blocks of proteins). Proteins have only a few amines hanging from them and the majority of nitrogen participates in amide bonds. Free amino acids have at least one amine group.
Now, randomly heating a bunch of organic molecules for long enough will inevitably yield reaction products between amine-bearing molecules and allylbenzenes, maybe even alkaloid derivatives of allylbenzenes. But the yield is going to be so low to be practical at all. It is a very long shot heating mixtures of complex chemicals and waiting for specific reactions to happen, let alone towards the direction you'd wish them to happen.
