Steam quality in steam sterilization process

 

Steam Sterilization process is defined as the action of exposing dry, saturated steam on the product to be sterilized for a specified time period under high pressure. Moist heat acts by denaturation and coagulation of protein, which eventually kills the microorganism.  The higher the temperature, the shorter the sterilization time required.  Wet steam, superheated steam and non-condensable gases all have the ability to adversely affect the sterilization cycle and therefore the sterility of porous loads. Steam of poor quality can contribute to wet packs and to sub-optimal steam sterilization cycles that might or might not be identified by biological monitoring.  Periodic testing of steam quality is needed to detect any transient or seasonal problems that may exist. Properly designed, constructed and maintained steam distribution systems are critical to meet the demand for proper sterilization.
