Colloidal Silver Production / Re: Gelatin substitute -- sodium caseinate
« Last post by Heino_R on March 02, 2024, 08:20:14 PM »Hello Kephra, that is for me very interesting . Sodium caseinate is a casein product which is probably also denaturalized with sodium hydroxide like the protective colloid of collargol, which was previously called sodium protalbinate.
I'm just wondering if there is a chemical relationship or if they are the same thing. Sodium protalbinate is produced by boiling casein in sodium hydroxide and then acid precipitation.
In the production of Collarol, it not only serves as a protective colloid, but also as a reducing agent.
Since it is a casein-based protein, the solubility of sodium caseinate is also likely to decrease at low pH.
Maybe you can test it by adding a little vinegar essence to see if the colloid will precipitate and then bring it back into solution with sodium hydroxide.
In my electrochemical experiments with sodium protalbinate there was the problem that the silver anode became coated with it.
For that reason I didn't pursue it any further.
