Inquiry Into the Identity of the Green Colour From the Spine of the Sea Pike

Inquiry Into the Identity of the Green Colour From the Spine of the Sea Pike INQUIRY INTO THE IDENTITY OF THE GREEN COLOUR FROM THE SPINE OF THE SEA PIKE BY M. WAGENAAR.

Abstract

INQUIRY INTO THE IDENTITY OF THE GREEN COLOUR FROM THE SPINE OF THE SEA PIKE BY M. WAGENAAR. The sea pike (Belone belone L.) is one of the few fishes, where in the skeleton a grass-green substance is secreted, which i.a. is the reason that this specimen, as an article of consumption, is not much in demand in comparison to other fish, that have a colourless bone. A green colour always arouses the suspicion of the consumers when it is found in articles of food of animal origin. The sea pike is a very convincing example of this. No information is to be found in literature about the identity of this pigment. The mere fact of its occurrence is mentioned everywhere, but not a single notice is made concerning the chemical composition of this colouring matter. The most reasonable supposition is, that this pigment is related to the blood-colouririg matter, haemoglobin. In order to be able to collect some information about this, it was tried to gather this pigment from the spine by extraction. Not by a single liquid this could be accomplished, not even by pyridin, the well-known means of extraction for haemoglobin and its derivatives. Evidently
