Thank you for the reply John. Reading my post again, I should apologise as I was not clear in my question

Also, maybe I posted in the wrong forum - it was the closest I could find yesterday to get the info I'm looking for.
Basically my question is to do with preparing raw seeds - e.g. sunflower, pumpkin, hemp etc. - for eating, by soaking them first.
Some types of seeds, after soaking for the first time, release a lot of their nutrients, oils etc into the water - and it seems a shame to throw it away. I was thinking I could use it as a stock? But not if it would contain anti-nutrients or stuff that should not be consumed. Or maybe when boiled these anti-nutrients - if present - would evaporate?
PS. If this is in the wrong forum, maybe someone who has privileges could move it to the right place.. thanks..
