Why not call "creamy stuff" oil will high gel point? That is what it is.

Hydrogenation is a commercially accepted process where unsaturated fats (those with double bonds) are chemically manipulated to saturate them (fewer double bonds).

Thus you can take a liquid oil like canola oil
And make it into a solid oil (Margarine to replace butter, shortening to replace lard).

Personally, I think the saturated (hydrogenated) oils are easier to cook with than the unsaturated oils. I.E. They have better anti-stick properties, and better for things like making pies and cookies.

Technically, Butter & Lard CAN be called "saturated", although truthfully they are a mix of oils, but they CAN NOT be called Hydrogenated since they haven't been chemically manipulated.

Shortening, however, is both "saturated", and "hydrogenated".

As far as HHO.
It is probably multi-fold.

• First of all, ignorance on the part of the system builder.
  
• Wish to make something sound new and unique for advertising.
  
• Hope for ignorance on the part of the people in the patent office... It is pretty hard to patent air.
  
• Easier to say than "Stoichiometric Mix of H2 & O2"

In a sense, I suppose it backfires a bit, because it just makes the system builders sound plain ignorant, and I certainly would loose faith in them when they are essentially trying to redefine Oxygen and Hydrogen.

saturated fats are bad! (as everybody knows) Especially the trans fats associated with hydrogenated oils that DO BOTH: increasing Low density lipo proteins (LDL) and decreasing high density lipo proteins (the good stuff, HDL).

Whatever people want to call separating the thick oil from the thin oil is fine with me, i just wish they wouldn't say fat.

Lard is saturated, the hydrocarbon chain is 'saturated' with hydrogens, not a man-made process but hydrogenated nonetheless. Lard is fat that is completely saturated, so it really can't be regarded as oil.

Yeah im surprised more people don't comment on how ridiculous it is with the HHO thing. "Water as fuel!" - water's constiuents is the fuel, not water itself, lol.
