Wow, I found it..
I didn't have a good technical description of the Silting step until today. Here it is in one paragraph..
Enzymatic Degumming of Rice Bran Oil Using Different Commercial Phospholipases and Their Cocktails
"Phospholipids are classified according to their degree of hydration (hydratable and
non-hydratable). Hydratable phospholipids (HPL) become insoluble in oil in the presence
of water and are easily separated by centrifugation. Most non-hydratable phospholipids
(NHPL) are complexed with calcium (Ca), magnesium (Mg), and iron (Fe) salts, and to be
removed, they need the addition of a chelating agent (citric acid or EDTA) to sequester
metal ions, allowing their precipitation and separation by centrifugation [5,6]."
This is how Silting is different than Winterization. Silting knocks out Phospholipids with water and acid. Winterization freezes and crystalizes the waxes which then settle out. Both are needed, one doesn't replace the other.
Silting needs deeper study for optimization. I'm not using heat, but it is used in the industrial scale. The optimal amount of water & acid need to be deduced. Optimal residence times need to be deduced. The end product has to be pH neutral. If you replace club soda with Body Armor pH9.5, it affects the cannabinoids.. Whole new rabbit hole.. One really interesting that can be done, take the pH to 7 and let sit for 6 hours. A whole new science is invoked - Isoelectric Focusing, aka IEF. Proteins precipitate at pH 7. The filter pads will go light green@1hr to almost black@12hrs. Its safe to assume the proteins are denatured (as a result of 90%+ alcohol wash). The proteins expose a non-polar side and bond to oil. So i think that is an emulsion. Its a protein rich dark green creamy emulsion and has a kick! It maybe a good base for a suave.
Enough for now..
