O.K., to refresh my memory, I went and looked it up in my old books because
the description you've given confused my aged mommy brain cells. And this
is what is in my books which is why I go along with the whole "toxic"
premise:
"Hydrogenated fats are oils that have been processed through a chemical
hardening method to achieve increased plasticity (stiffness) of the liquid
oils at room temperature. Partial hydrogenation (brush hydrogenation)
hardens oils but does not make them fully solid. Full hydrogenation
requires complete conversion of a liquid oil into a solid fat at room
temperature (72 degrees F). A fully hydrogenated oil has natural saturated
fats left intact and all the remaining mono- and polyunsaturated fatty acids
become converted from their fluid configuration to a full trans fat rigid
configuration. The process is as follows:
1 High heat
2. A metal catalyst such as nickel, zinc, copper or other reactive metals
3. Hydrogen gas
The metals are used to react with the hydrogen gas which is bubbled up
through the mixture. The metals catlyze the hydrogen and carbon atoms and
convert the fatty acids by flipping one of the attached hydrogen molecules
and rotating it half the diameter of the carbon chain.
This effectively creates a new molecular shape resulting in a stiffer or
more rigid material, hence the change from a liquid to a semi-solid or solid
substance. This new shape stiffens with the hydrogenation process making
the oil behave more like a saturated fat (such as coconut fat which is 92%
saturation and solid at room temperature).
Trans fats are the result of this reaction.
Partial hydrogenation, or "brush hydrogenation" is a minimal conversion step
which only offers a small degree of reaction by hydrogenation. Brush
hydrogenation increases stability for volatile fatty acids like the omega 3
(alpha-linolenic) and omega 6 (linoleic) poluunsatgurated oils. Most
commercial salad dressing oils, such as soybean oil, have been brush
hydrogenated.
Hydrogenation raises the melting point of the fat and retards rancidity
(which is why they are doing it to lard).
Now, on to Trans Fatty Acids. They are synthetic saturated fats which is
why they are a problem Most of them are man-made although you can find them
naturally in cow's milk that has up to 14% butter fat. They also occur in
vegetable fats through hydrogenation.
Now, if you like to look at pictures of those cutesy molecule ladder
thingys, hydrogen molecules attach at the center of the fatty acid carbon
chain flips 180 degrees which straigtens out the natural curve or kink in
the typical cis-configured fat. That's why the "trans" label (cis-shape
chmically alters to a trans configuration).
So, bottomline is that saturated fats are natural and trans fats are
chemically produced.
The best way to look at saturated vs. trans in the equation of good vs. bad
fats is the old Micky D's French fries. The fries used to be cooked in
tallow. Tallow is a saturated fat. Now the fries are cooked in a partially
hydrogenated fat or a hydrogenated fat (depends on the individual M D's).
Probably because the word "saturated," folks are inclined (my theory and not
scientifically proven <g>) folks are inclined to think that things cooked in
"saturated" fats are greaser and this is not the case. For whatever reason,
cooking in lard or tallow is not as greasy (retained oils) as cooking in
hydrogenated or partially hydrogenated oils. 30% or more less retained oils
(depending on the quality, heat and age of the fryer fats).
