Sterilizing w/o a PC theory?
    #5309045 - 02/16/06 10:31 PM (17 years, 11 months ago)

OK, so this has probably been thought of already, but I did a search of the site and didn't find it. That being said, I'm probably missing somthing, so feel free to rip me a new one for being dumb.

Here it is:

Pressure cooker's work so well because they raise the boiling temp. of the water, right? So what if you put your jars in a container filled half way up the jars with water and covered it tightly with tinfoil, then placed it in a 350 degree oven. The water would keep the jars from drying out, and the temp would get high enough to kill anything.

Is this a sound theory, or is it total crap?

Total crap, sorry. The water will just boil away at 212 unless you have pressure.

Look into fractional sterilization if you want to try and skip a pc (you will buy a pc after trying that method I bet)

OMG You are sooo dumb - J/K noones going to think your dumb for asking a question, the worst youll get is "do a search".

From what I understand is that the pressure also help to Penetrate the grain where endospores are held./

What if the foil was left off, so the jars were exposed to the hot air itself? Would the jars dry out or would the water in the pan and the foil on the lisd keep the atmosphere moist enough. Sorry if this sounds dumb but it's just an idea I've been kicking around. Thanks for the honest opinion though.

If you are using the very basic PF tek you can get by without a PC but if you want to use grains every source I've found, recomends that you do PC the grain. You can sterilize most dry ingredients by baking them, but you risk reintroducing contaminations as soon as you take it out of the oven. Maybe it would work that way with a combination of steam canning if one had an absolutely sterile kitchen, I don't know. Of course an autoclave would be ideal but who can get ahold of one of those. No, to be sure, I intend to save my pennies up and get ahold of a pressure cooker before I switch over from BRF to grain.

love, revbear

OMG. This is like th fiftieth time Ive posted this.
Fractural Sterilization
(Ive only done this with wbs)

Soak for 24 hours.
Rinse for at least 5 minutes after soak.
Place in jars, with lids half way turned.
Place jars in water thats equal to half its width.
Boil for one hour.
Let sit for 24 hours, then boil for another hour.
Let sit again for 24 hours, and boil again for the final time.
Let cool.
inoculate.

Ive never had contams with this method. A little Verm in the jars (1/10) helps retain moisture throughout the process, and is HIGHLY recomended.

Of course one can't argue with results, but aren't you still not attaining the really high temperatures to kill all the nasties? ? ?

The nasties are the endospores. With fractional sterilization you allow them to germinate by incubating in moist good conditions. Then they start to grow and are easily killed once "out of their protective shell"
