I was doing some research into flavorless (or flavor-neutral) acids that could be used to create certain things without altering the flavor of the outcome (say, an emulsion).
Stearic acid immediately came to mind because it's known to be associated with lowered LDL cholesterol when compared to other fatty acids, and it naturally occurs in many proteins such as beef / chicken / most fish. I knew it doesn't taste like anything because my parents ran a candle business out of our basement growing up, and I accidentally grabbed some thinking it was sugar, and was quite surprised when I tasted nothing.
I looked at a study which also breaks down the average content of stearic per 100 grams of various proteins and adding a few milligrams of it to something like a sauce definitely seems like it could be in the safe realm of possibility.
But I can't really find any references to any real culinary use for it other than its natural occurrence, which led me to wonder why it's not a more commonly used additive for the properties that it has? I'm also not certain if I'm over-estimating the efficacy of it used as an acid. I've never used it in any of the kitchens where I've worked.
Does anyone know more about it?
