pressure cooking plastic or tupperware
    #577892 - 03/13/02 01:15 PM (22 years, 20 days ago)

i have a 6 quart plastic container- it is really thick plastic. it doesn't even have a recycle number on the bottom. i think milk jug containers are number 2 (if that means anything to anyone). i think it says "pp" (polypropalene [sp?]) on the bottom. it has a lid made out of the same material. i also have some 3 quart plastic containers that do say "pp" on the bottom. and the lids have recycle number 5 i think. i want to use these as spawn containers- but i need to know if i can put them in my pressure cooker at 15psi for about 70 minutes (in order to sterilize wheat berries)?? there is already a little metal thing in the bottom of my pressure cooker so the containers won't be sitting directly on the bottom- but i will also put a wash cloth underneathe just to be safe.

anybody done this before? are these gonna melt? thanks for all responses.

If they donot melt they will possibly warp, and since you donot have a separate band and lid, air exchange will be difficult. Not a good idea. But thats just an opinion.:). Just use canning jars and be safe.:)bluhoney

If you want to sterilize casung then just use those ovenbags, theyre usualy in the ziplock bag section at the grosery store, and theyre cheap and reusable

Not true - i have PCed and my friend says you can even autoclave good quality tupperware. If they are empty they may buckle, but if they are full of substrate, theyll be fine

PP = Polypropylene = 5 inside a triangle

Is the only plastic that we can use safely in a PC at 15-17 psi during a 2 hours cycle, if it melt is not PP or your PC is reaching somewhere between 17-20 psi which some PC do reach. BEWARE that is pretty normal for PP container to have a not PP lid, i think thats probably because when is microwaved you need to remove the lid anyways to heat the food so some companys i asumme that prefere to save money on lids with cheaper plastics.

If you want to use with grains then just make a hole or 2 in the lid and put micropore or a filter of choice for gas exchange.

I have not done it but i pretend to try it when i find some really volumen efficient and sturdy container that fit in my PC.

Only for safety dont use thin plastic containers even if it is PP.
