  freeze-dried \freeze-dried\ adj.
     dried by freezing and applying a vacuum; -- used of tissue or
     blood or serum or other biological substances.
  
     Note: This technique is gentler than other drying techniques
           and caused less damage or deterioration to sensitive
           substances. It is used primarily as a method to
           preserve foods or substances, and permit storage
           without deterioration.
  
     Syn: lyophilized, lyophilised.

  Freeze-dry \Freeze"-dry`\ (fr[=e]z"-dr[imac]`), v. t. [imp. & p.
     p. Freeze-dried; p. pr. & vb. n. Freeze-drying.]
     to remove the moisture from (e.g. food) by first freezing and
     then subjecting to a high vacuum; -- used as a mild method
     for drying foods or chemicals while causing little
     decomposition, in contrast to heat-drying.
  
     Note: This is a relatively gently drying process used to
           preserve food or sensitive biological materials. For
           biochemical materials, the term {lyophilize} is often
           used.
