Propylene Oxide (PPO) Pasteurization Technologies


Propylene Oxide (PPO)

Propylene Oxide (PPO)Using technology developed for the medical device and pharmaceutical industries our propylene oxide pasteurization process, PPO Express, is an improved method for treating herbs, spices and nutmeats. 

The process yields a 2 log greater lethality on many products than conventional PPO pasteurization and dramatically reduces post treatment aeration time.  Cosmed Group’s proprietary process reduces the time required to pre-heat almonds and other nuts by several days.

Propylene oxide is approved for use on spices, nutmeats, dried vegetables and cocoa powder.
