The quality or state of being albuminous; the degree to which something contains or resembles albumin.
From 'albuminous' + suffix '-ness' (state of being). This abstract noun formed part of 19th-century scientific terminology for describing protein content.
Adding '-ness' to '-ous' adjectives creates a double suffix effect that's almost comically specific—it's like asking 'how much the quality of being albumin-like-ness exists?'
