Moist Heat Sterilization One of the most efficient methods of sterilization is moist heat sterilization, in which steam under pressure kills bacteria. "Understanding and Utilizing F0 Values," Pharmaceutical Technology, May 1978, pp. 13.3 Heat penetration studies should be conducted with the maximum and minimum loading configurations for each sterilization cycle using the sterilization parameters specified for the normal production cycles. For moist heat sterilization, saturated steam that hits a cooler surface than itself will increase the temperature of the surface and release heat of condensation during the phase change of water from gas to liquid. It must be recognized that, regardless of the sterilization process, the control of manufacturing environments and good manufacturing practices which provide barriers to microbial contamination remain of utmost importance. pressure sensors for jacket and chamber pressure; conductivity monitors for cooling water, if applicable; water level indicators when cooling water is used; thermometers including those for thermocouple reference, chamber monitoring and all laboratory testing. Parenterals are filled in an aseptic area of at least a grade B environment or in a grade A zone with at least a grade C background before terminal moist heat sterilization. The determination of the minimum "F0" value for the Probability of Survival approach is based upon the number of microorganisms (bioburden) found in a given product and their heat resistance, as described in Section 10.3. Validation studies must assure that this unit receives the minimum required "F0" value. If the results are satisfactory, the system should be certified. Moist heat sterilization destroys microorganisms in a product with steam under pressure. The probability of survival is determined using a semi-logarithmic microbial death curve, where a plot of the log of the number of survivors versus time at a fixed temperature yields a straight line. Moist heat kills microorganisms by coagulating their proteins quite rapidly and effectively. You will not receive a reply. Why do you think that carbohydrates are not digested in the stomach? Privacy Policy3. Technical Monograph No. Compliance and enforcement: Drug and health products, 3. At the beginning of the sterilization process for water cascade autoclaves, no air in the chamber is removed.
