what is "freezer taste"?

[eub]

There's a characteristic taste that everything stored in a freezer takes on, no matter what the food is itself. What is that taste?

• cryophilic microbiological flora
  
• plasticizer in freezer door gasket material
  
• actually not a foreign addition, but characteristic of freeze-drying

I've had freezer-burn-taste ice cubes from a freezer that contained *nothing* but (very old) ice cubes. I'm a bit curious about this.

My favorite theory is cryophilic bacterial biofilm. Sporulates to survive above-freezing temperatures, of course. Infests commercial freezing facilities.

I'd like to see what's common between two freezers. Can one logical-AND two GC/MS outputs.
