Quote:its possible you added salt with the anti-clumping agent + iodine and therefor you got the mushy harmala...
How would anti-clumping agents or iodine cause it? Anti-caking agents (you can find a list of them in wiki) and iodine (in the form of salts with K or Na) are usually added in small quantities and i cannot see how they could turn the whole thing into a mush. Unless of course they react with something in the plant that causes this phenomenon: in this case ,and i am just speculating, if what forms is water soluble then repeated washes with brine could remove it (or the wash with base if it cannot dissolve in brine), if what forms stays insoluble then reconsituting it with water and filtering can even help since it would remove more impurities in solid form.
I had extractions like those turn into mush, but they were from big quantities of peganum harmala. I do not know if its tannins or something else but i too have noticed it. Even if you let peganum harmala tea stand in room temperature you might notice those "clouds" which i think its the same material ,given that they look way dispropotionate to be harmala alkaloids falling out of solution compared to the amount of seeds used.
Anyway, i am throwing ideas on the table, i am not sure if any of my thoughts are correct.
