Bleach and heat!!!

Question for ones who might know !!
What happens to bleach in small quantities when exposed to heat? does it break down and evap or simply heat up and stay put ???
the idea is this:
For those who do not have a Pressure cooker, could one do wbs/grains with bleach and water, then steam/boil them a la PF tek?
Would the grains turn white and to a mush.. or would they stay intact and bacteria free?
I need to find the boiling point of bleach.
anyone ever try this before? Instead of the high heat that 15 lbs of pressure provides, could one use the anti-bacterial effects of bleach combined with a steam treatment to disipate the bleach

Here is some good reading about bleach. It says....
Sodium hypochlorite slowly decomposes through the action of light, heat andmetallic or organic impurities with oxygen emission.Sodium hypochlorite suddenly decomposes through the action of acids withchlorine emission.
Hope that helps

The problem with using bleach would be that it reacts with ANY protein and organic source very rapidly, then rendering it useless. There is no way, which I'm aware of, for bleach to specificaly target something of interest. The grain you would be using would be high in proteins (making it a good substrate) meaning, in order to make sure ALL contams have been inactivated by bleach you would, in the process, be chlorinating all the proteins in grain rendering them relatively useless and possibly carcinogenic. Bleach has been used in the the process of pastuerization with the help of alkaline solutions. Stamets talks about this in one of his books, don't remember which one. And you wouldn't be looking for sodium hypochlorites boiling boint just the temperatures at which it degrades.

That would be Growing Gourmet and Medicinal Mushrooms , Page 175 . In this application it is just used as pasturazation for straw .

Hmmm. interesting..
I had not thought of what would happen to the nutritional properties of the grain once bleached... good point..
I will give it a try for the hell of it tonight tho.. i'll report back in a few days.
Thanks for the info guys!!

it works wonders in the pasteurization of straw when combined with the proper temps and proper PH

from my experience heating things that have been soaking with bleach solution, there is no residual residue noticed. this has been done with several dozen batches of homebrew that I've made. no taste difference, no odor. always fermented fine. temps were boiling 60 - 90 min. roiling boil.  bleach will evaporate out of a liquid given enough time. pool owners know this.
also, I never use bleach anymore. there are better solutions. check for iodine. works wonders and you can let it drip dry.

Found this old post. I was planning on soaking grain in bleach solution for a week. It might give time for the endospores to germinate, and I can get away with simply microwaving. Does anybody know what sort of concentration I should be using to kill the common germinated endospores?
I have sucessfully colonised 20g of dry wheat which was soaked for a week and microwaved once for 25mins. I think this may have been a fluke and want to try again with more grain.
I plan on adding boiling water on day one, and bleach on day 2 when it has cooled. I know I will have to rinse well at the end of the week, since the bleach will decompose into salt upon final heating.

food industry standards for a bleach sanitizing solution are 200ppm. peace

That sounds very low, only 0.02% if my maths is right. I was thinking more like 0.5-1%. 200ppm may be for drinking water but I think it would need to more to kill germinated endospores.
I am also thinking of microwaving the dry grain before soaking, this should kill it and stop it from germinating, as well as killing some nasties to begin with.
