Re: conservation of albumen

Please disregard my previuous message, I was thinking to save a proof 
instead of sending it.

For sure, when albumen paper was made they were whipping eggs all the day, 
and the process was like an assembly chain. I don't believe their albumen 
solution would last for more than 1-2 days before being replaced or 
replenished with a new one.

The week or more needed to break down the proteins and partially denature 
the albumen is what I would prefer to avoid for sake of practicalness, but I 
know I can't because fermentation is needed to destroy glucose. This last is 
the responsible of the long-term yellowing of albumen prints (Maillard 
reaction).
I would use albumen both for making a double albumen paper and simply try a 
different sizing, so I would prefer to beat and ferment eggs only once.
