What else can I help you with?

Why you sterlize at 121 Celsius temp for 15 minutes in autoclave?

The sterilisation temperature is defined by the spores of the Geobacillus stearothermophilus. The spores have a D-value of 1,5 min @ 121°C. D-value means decimal reduction criteria, so it means, that after a treatment of 1,5 min (90 sec) at 121°C 90% of the bacillus spores have "died". For your process that means a 10x 90% reduction, a 10D concept. This means after 15 min @ 121°C 99,99999999% of the spores of G. stearothermophilus are "gone". Usual, the food industry demands commercial sterility, which is defined with a 12D concept. The regular sterilization requirement is usually 20min @121°C (or 5min @ 135°C). Where is your 15min@121°C sterization concept used? Cheers, Abraxas
