H202 hurts cakes?
    #3286961 - 10/27/04 11:15 PM (12 years, 6 months ago)

Well My friend dunked a Cake today and he said He poured the water in leaving the floating cake at the surface and he then added about a half cap full, but some h202 directly hit the top of the cake and made an acidic burning noise. He quickly poured some water over that and got the cake submerged and into the refridge.

Think everything is ok?

from what I've read the H202 should be cool. I've read some people add a whole entire cap full.

It might have been killing contams.

doesn't sound good. You get that stuff when H2O2 reacts with enzymes... possible bacterium culture in that thing... pour another capful of H2O2 in the water and see if you can get it to fizz again.

Forgive my massive retardation, but what is H202? Is that hydrogen peroxide?

H202 is hydrogen peroxide. I had to use h202 to sterilize a cut a my arm and when it touched the blood or scab it would fizz but its supposed to do that, so maybe theres an enzyme it reacts to as sam said.

You should never pour straight H2O2 on a cake.

Yes you can and its fine. Everyones getting you all worried about it. People should know what is going on before they start telling you. Anyways..

Most living organisims produce an enzyme called peroxidase. Grains produce it, bactiera produces it, molds produce it, fungi produces it, even you produce it (never poured any on your cuts?). Peroxidase breaks down Hydrogen Peroxide (H202) into H20+0. The bubbling is the O (oxygen) leaving the H2O (water). Its perfectly normal, natural and safe. It's not good to submerge your myc in straight 3% h202 but as long as its not stronger then 3% you can pour it directly onto cakes, myc, whatever. Just pour some regular water over it after to let it mix in well. You can also mix the solution down to .3% first in a glass then pour it over the cake. It will still fizz if you listen carfully but its fine.

Ya, Scatmanrav is right there is nothing to worry about. The h2o2 fizzes like that whenever it touches anything, pour it on some flour and it will fizz. You got nothing to worry about its normal and the fizzing cant hurt the cake.

Technically it won't fizz on everything! That noise you are hearing is just as it was said before, some kind of bacteria and a possible contam. H202 is actually water with an extra atom of oxygen. When those ions combine chemically with the chemicals present in the affected area, the H202 gives up the extra O atoms causing "energy" which in turn causes a high degree temperature change that "sterilizes", in a way the area and the bacterias. It's kinda like PC'ing or Steam sterilazation, that we use all the time....

i also have some questions about using h2o2:
-would you use it in the water used for misting? in which percentage?
-would you use it in the casing mix? in which percentage?
-if used in the casing, would that be an alternative to PCing?
-would that delay or avoid colonization of casing?
-would you use it in the perlite+water method for humidification?
-using it also in the substrate would kill the spores?

Wow ... Well let me see...

1. Yes, usually it is mixed in a 1/10 ratio.
2. No because you should still steam or PC.
3.NO!!!!!!
4.It would actually make no difference because when you sterilize it the steam or PC is going to be better than the addition of H202 in the beginning therefore wasting precious h202.
5. Definitely use the Perlite+Water method..especially if a beginner.
6. I would say yes but not as confident so thats open...

I cant say I agree with alot of what is in that article. Sterilization should occur along with H2o2 application, not in replacement of. He seems to swear by peroxide as the only necessary step in a sterile enviornment. That seems to be setting up failure for a newb.

Has nothing to do with heat. H202 inhibits the germination of mold spores and helps to stop contamination. Have you ever tried pouring it on cobweb or the green? If you stop application to cobweb affected material then it will come back. Large amounts of H202 will hurt cakes and thats why it is mixed with water to almost nothingness. I'm not sure at this moment how it damages the mycelium but i read it before in the contam forum somewhere.

If you would like to find some better answers then use the search function.

This is NOT how H202 works. It works as I said an enzyme is produced by contaminants and mycelium (among many other things) called peroxidase that breaks the h202 into h20 and 0. That part you were correct about. This does not generate heat and does not sterilize the area though..you actually don't want fizzing because that means the peroxide is turning into water. If it kills spores (which is ALL peroxide does for the most part) it won't fizz. Look it up if your so inclined to not believe me.

The guy in the article is absolutly correct and h202 CAN be used in certain substrates. Grains will not work and therefore cubies can't really be grown by this method which is why you don't hear about it. It definatly does work for edibles grown on wood and can work in other casings.
