Is there anything valuable to extract from acorns?
I have 2 very old oaks growing near the border of my homestead. There is a lot of acorns in grass and on a road, they should be collected. I was
inspired once looking how Fery can extract something valuable from anything growing on his land. So, I'd like to follow his approach. Is anything
valuable for organic chemist I can extract from acorns by means of chemical treatment or fermentation?

Probably a read of this article
https://en.m.wikipedia.org/wiki/Acorn
can give some ideas that could be followed up using the links and references
looks like a good starting point.
I found Chapter 6 of the first reference quite interesting.

Gallotannin
From a previous thread:
Extraction of gallotannin - Ideal method?
Quote: Originally posted by UnintentionalChaos ![](images/xpblue/lastpost.gif) | I believe only certain types of galls work for that. Red oak acorns sure as hell work. Boil a few in water and then add a tiny bit of ferrous salt
solution (I had rusty nails soaking in vinegar) and it goes inky-black. I did this before I even really got into chemistry as an attempt to dye cloth
black without store bought dyes (I got gray at best).

This is really interesting how the evolution of plants and animals go in connection with each other.
The part of acorns in the garden are already germinated.
Probably I will try to add yeast to see how much carbohydrates could be converted to alcohol.
As for tannin I will look how to break big molecules in some smaller and more useful ones.

°F or °C?
Edit: OK, °F. I suppose so.
Acorns can be up to 30 percent fat. Won't that mess up with fermentation?

I probably will try. This year they are mixed with fallen leaves already. I need several dozens families of squirrels to help.
By the way, I read it is better remove tannins with cold water because hot water removes glutene like substance which is good for baking.

Ether way if you don't get all the tannins out, your going to have an upset tummy.

Well, if you put them outside at the right time of year, you can extract venison from the pile if you have a rifle.
