The Oven Is My Friend!!!

Why do we use pressure cookers for starlization? Why Do we not use the oven? My oven can hold alot more jars then them pc can.

when you pressure cook your jars do you let them seal? like you would can anything else...

Whole grains need to be PCed, PF Tek can be boiled. Neither seals the jar, that would be bad, and neither can be just stuck in the oven because thats a dry heat. If you want to experiment with the oven feel free, however the best way to get consistant results is with a PC, that is why we use them.

Have you ever tried to inject canned food with a syringe in order to sterily start an organisim and give it room and air to grow?

We arent canning food, were creating jars. If you create a vacuum inside the jar, not only will you not have a hole to inject into the substrate, but if you were to try and lift the lid to squirt in some spores (a bad idea anyway) you would suck in air and contaminates.

Oven cooking a jar will dry it out, if it is sealed it will explode due to pressure build up. Moist heat is far more effective in sterilization than dry.
