A microwave‐permeable chamber was constructed for high temperature sterilization of foods in glass containers at overpressures up to 50 psig. Temperatures could be monitored satisfactorily in the microwave field using stainless steel shielded type T thermocouples if the metal sheat were grounded. Percent fracturability did not differ between potato samples sterilized by microwave energy (1000 W output) and stem. Extrapolation of kinetic data indicated that although fracturability retention is quite low at temperatures below 150°C (<15%), it should increase dramatically above 160°C (>60%). Verification of this will require a higher microwave output (>1000 W) than was available in these experiments.
