(STICKY?) Rice & Protein - Yum (STICKY?)
    #8586841 - 07/02/08 06:08 AM (15 years, 8 months ago)

I thought it might be of interest to the beginners, and maybe more advanced growers, that rice can undergo a complex chemical change during substrate preparation.

During food shortages in the East, protein wasn't readily available, just lots of carbohydrates in the form of rice.

Some cleaver people discovered that rice grains contain enzymes. And that when the rice is damp and warmed, these enzymes become active - breaking down some of the carbohydrates and other stuff in your average grain of rice into proteins.

They found that this could be achieved by wetting the rice and then letting it sit for 24h around 25 - 30C.

A home grower could implement this in something like the PF-Tek by making their jars and then sitting them somewhere warm for a day.

The advantages;

Mushrooms like carbohydrate as their primary food source, which they enzymatically digest into sugars for dinner. But they also need a quantity of proteins to build other important enzymes and produce useful metabolites - like psilocybin. This is why growers using just pristine white carbohydrate (white rice, flour etc) don't get the same quality in the result as those using rich compost - the latter is a tasty complex mix, containing lots of trace nutrients that are missing from the more simple substrates. Growers will try to account for this by adding things like pollen, yeast and other protein sources, but for the average home grower that's just more to think about.

Also, many bacteria and contaminating fungi form spores by encapsulating themselves in polysaccharide capsids (shells). This makes them SIGNIFICANTLY harder to destroy with heat - to the point that some are invunerable to regular sterilisation methods. By allowing the mix to sit somewhere warm overnight, the contaminating spores are able to germinate. Once they do, they loose their protective shells and become much easier to thermally destroy - just make sure you don't leave it for too long or they'll start building up in numbers and then you potentially loose the advantage you intially gained. This is scientifically known as fractional sterilisaion - incubate, sterilise, incubate, sterilise, incubate, sterilise and so on to ensure anything left germinates and is subsequently destroyed.

Enjoy

Nice thoughts :smile:

Well i dont think it will make a big difference in 1 cake hervast (using BRF or the method above)
