Nutritional content of grains
    #6770853 - 04/10/07 03:34 PM (17 years, 9 months ago)

Just out of curiosity, I looked up the nutritional content of often-used grains in mushroom substrates, and found some figures. I only list carbohydrate levels here, as I'm pretty sure they're the only thing mushrooms are interested in.

Brown rice (both long and medium grains), 25% carbohydrates

Rye, 23%

Millet (major starchy grain in wild bird seed), 24%

Quinoa, 22%

An interesting point is that grains (or brown rice, at least) lose a lot of carbohydrates when cooked (the carbohydrate level drops to 7%). Are the carbohydrates actually destroyed, or are they lost to the environment? If they're destroyed, wouldn't it be lucrative to figure out a way to sterilise PF jars without cooking the rice flour?

Another point that interests me is that cornstarch has a 30% carbohydrate level. Why isn't it used in PF jars instead of brown rice flour, or white rice flour, come to that, as white rice seems to have a higher carbohydrate content of 26%?

Thanks in advance.

(P.S. Tiny side question, something that's been bugging me today. When inoculating jars, teks often instruct one, after flame sterilising the syringe, to cool it by squirting a little solution out. Couldn't you just have a beaker of clean water handy to dip the syringe in?)

I dunno that 1% difference is anything to even worry about. There are WAY to many other variables that play a much larger part in getting good yields. One time you may get a better grow using rye over millet, next time you might not.

And why make things more complicated with the syringe? Keep it simple man!!

Often, MILO (sorghum) is the major seed in WBS.

Just keep the needle wrapped in an alc soaked gauze pad.
At all times.
I have almost never flamed a needle, while inoculating.

Well, I think I'll do some experiments with cornstarch cakes (vs. my current grow, brown rice flour cakes) and see how that goes. I'll post results here (could be some months yet). 5% could make some difference (plus, saves having to grind up the brown rice), though finding organic cornstarch may be slightly difficult.

Still no thoughts about the carbohydrate loss in cooked grains?

Try some oatmeal, that's probably got some carbs in it, lol
