This was a big fad back in the 1970s before crtical point drying came into vouge.  There were papers on it, maybe in the Bulletin of the ESA, which was not indexed.

Subject: Freeze drying soft bodied specimens

Is anyone out there freeze drying specimens? Is there any work on what happens to DNA or the internal anatomy of a freeze dried specimen?

Pinned specimens (or at least specimens not in alcohol) tend to be more "available" to the public in displays, and most specimens are bleached by alcohol preservation. Freeze drying might offer a way to preserve different characters and make more visually appealing displays.

Any advice, etc. is appreciated.

Thanks,

Mike
