Partially hydrogenated oil and NO trans fats?

A product I was looking at (a chocolate bar) list "partially
hydrogenated palm kernel oil" among the ingredients, however it claims
to have 0 Trans Fat. How can that be?

I thought trans fat is always formed when vegetable oils are
hydrogenated.

What brand is it? Anyway, try real pure chocolate, which contains cocoa
butter and no other vegetable fats! Smile

Hmmm...
I asked a similar question a few weeks ago ("A few questions about
hydrogenated fats"). And MMu replied:

However, I read...

http://www.mypyramid.gov/pyramid/discretionary_calories_fats_how_print.html
| Foods containing partially-hydrogenated vegetable oils usually contain
| trans fats.

They say "usually", not "always".

Besides...

http://www.mypyramid.gov/pyramid/oils.html
| Check the Nutrition Facts label to find margarines with 0 grams of trans
| fat. Amounts of trans fat will be required on labels as of 2006. Many
| products already provide this information.

But such a label might refer to margarines with no hydrogenated fats at
all, I suppose.

At the end of day... sorry, I don't know the answer! :)

This happens because the stated "0" per serving only has to be "close"
to the actual value per serving, not exactly the actual value per
serving. I forget the amount of leeway you have, but I think it's
close to 25% plus or minus the actual value, but I could be wrong.

It can be a mix of completely hydrogenated oil with non-hydrogenated
oil. Such mix in right proportions would have the consistency of the
partially hydrogenated oil, but won't have trans fats. Sometimes such
mix is still called "partially hydrogenated oil".

How much polyunsaturated fat does palm kernel oil start with?

They say "usually", not "always".

The reason to this is, and I think I also mentioned that in the discussion
where the quote is from, that the hydrogenation process is getting better
and better. The ammount of trans fatty acids that results from a modern
hydrogenation process (new catalysators etc) is very small to practically
zero.

I would expect the "0 trans fats" to be read as "0 grams" which basically
means that there might still be trace ammounts in there but not in the area
of one gram.
Trace ammounts of trans fats are absolutely harmless.. trans fats are not
the "killers" anyway because the ammounts are very small and they have
similar properties to saturated fats when it comes to LDL cholesterol.

My understanding is that the serving size is reduced until the transfat (or
sugar) is less than half a gram per serving. They are then allowed to say
zero on the label, even though the product may, in fact, contain the trans
fat or suger. It could be 10%.
