gelatin to clean dirty oil

J. Kenji Lopez-Alt of The Food Lab breaks down how and why this technique works in the link below, but I’m going to go ahead and share this game-changing method with you. First, let your oil cool, so as not to burn your precious self. Pour some water into a pot and sprinkle with gelatin. (You’ll need half a cup of water and a teaspoon of powdered gelatin for every quart of oil you plan on clarifying.) Let the gelatin bloom for a few minutes and then bring the water to a simmer, stirring until the gelatin dissolves. Add the dissolved gelatin to your dirty, filthy oil, and stir, stir, stir. Cover it all up and place in the fridge overnight. The oil will float to the top, leaving behind all sorts of burnt bits and gunk in a neat gelatin disk. Pour it off, discard the disk of doom that remains, and use your clarified oil to fry up something tasty.

I think this could work for removing the junk from really bad oil. What you think?[/B]

Well, its going to remove anything that would settle out anyway. Might be able to argue it will also pull some more moisture out of the oil due to the hygroscopic nature of a near-saturated sugar solution.

what sugar are you referring to?

It will require about half a cup of gelatin to clean 5 gal of UVO.
Unless one can find a cheap source of gelatin, this is going to be an expensive way to clean UVO.

Yeah, I suppose, the proposal is straight gelatin, I was thinking making a bunch of actual Jell-o. Smile

Gelatin itself is still pretty hygroscopic, not as well as something like a hydrogel would do as compared to water absorption per unit mass, but still.

Exactly. Besides the expense of gelatin, I object to adding any water to the UVO. If one wanted to use this method, then adding the powdered gelatin directly to the UVO might be a better idea.
