Hello Hummer-Ga
You took my question abit wrong,but it was my fault.I didnt specify
clearly enough,but the request was regarding how is the folic acid in
the fortified foods and grains made,from what is it obtained (I.e.
vegetables,fruits,animal derived,etc) and perhaps the process of how
they make it.

Hi justadream,
I'm sorry for the misunderstanding. The Folic acid which is added to
grain products is the synthetic form.
"Synthetic (manufactured) folic acid is added to grain products,
including flour, rice, pasta, cornmeal, bread and cereals. These foods
are considered ?fortified? with folic acid."
http://www.marchofdimes.com/professionals/14332_1151.asp
"The synthetic form of folate in fortified foods is 1.7 times greater
bioavailability than forms found naturally in food."
http://www.feinberg.northwestern.edu/nutrition/factsheets/folate.html
As it happens, the Wikipedia link I gives you contains all of its properties.
Folic acid
http://en.wikipedia.org/wiki/Folate
Here are some more links which should give you a pretty good idea what
Folic Acid is.
Folic Acid [view three images]
Folic acid is a water-soluble B complex vitamin that is required for
animal metabolism. Sometimes alternatively known as vitamin B9, the
substance can be found in a wide variety of food items, such as green,
leafy vegetables, brewer?s yeast, soybeans, wheat, and liver."
"Folic acid was initially isolated from spinach leaves, an event that
resulted in its common name, which is derived from the Latin word
folium, meaning ?leaf.? The vitamin was first produced synthetically
in 1945, and since that time has been included in a wide array of
supplements and many fortified foods, such as cereals."
http://www.olympusmicro.com/galleries/polarizedlight/pages/folicacidsmall.html
Folic Acid: Water Soluable
"Folic acid is a conjugated molecule consisting of a pteridine ring
structure linked to para-aminobenzoic acid (PABA) that forms pteroic
acid. Folic acid itself is then generated through the conjugation of
glutamic acid residues to pteroic acid. Folic acid is obtained
primarily from yeasts and leafy vegetables as well as animal liver.
Animal cannot synthesize PABA nor attach glutamate residues to pteroic
acid, thus, requiring folate intake in the diet." [see graphic]
http://isu.indstate.edu/mwking/vitamins.html#folic
Folates are a class of naturally occurring compounds (polyglutamates)
with the vitamin properties of folic acid. The synthetic forms of
folic acid contain only monoglutamates. Polyglutamates must be
converted to absorbable monoglutamates in the upper small intestine.
(7) Synthetic folic acid supplements, therefore, provide better
bioavailability than folate from natural source, an important concept
when determining the best way to deliver adequate amounts of folic
acid to the target population (see below). "
http://www.obfocus.com/nutrition/nutrition1.htm
Although folate (the natural form) and folic acid (the synthetic form)
are very similar in structure, folate is not as stable as folic acid -
it is more easily damaged by cooking and processing. Also, food
folates need to be broken down in the digestive system before the body
can absorb them. This means that folic acid is absorbed more
efficiently than the natural form of the vitamin."
http://www.nutrition.org.uk/upload/Consumer%20booklet%20folate%20final.pdf
Sorry to say, I don't believe a description of the manufacturing
process is available online.
I hope we are finally on the same wavelength!

hummer

Hello Hummer,were getting close.
You mentioned in regard to folic acid being possibly derived from animal liver.
I need some information on that,for example,what kind of animal,and
mainly in which kind of products.Another one is if vegetable derived
folic acid is used in enriching grain products like cooking rice,or is
animal liver used instead?
And what about the "Acid" in the Folic Acid,does that mean it has some
alcoholic acidity in it? is folic acid fermented somehow? This might
be alot of work for you,but Im giving you 50$ as a tip whenever the
answer is sufficient.

Hi TY,
1) You mentioned in regard to folic acid being possibly derived from
animal liver. I need some information on that,for example,what kind of
animal,and mainly in which kind of products.
Liver is a very good source but I don't believe it is being used to
enrich our food supply. Perhaps in some supplements, but not in grain
products. I haven't a clue what kind of animal, I doubt there would be
just one animal but several.
WATER-SOLUBLE VITAMINS
"With the exception of vitamin C (ascorbic acid), water-soluble
vitamins belong mainly to what has been termed the B complex of
vitamins. The better-known B vitamins are thiamine (B-1), riboflavin
(B-2), niacin (B-3), pyridoxine (B-6), pantothenic acid, lecithin,
choline, inositol, and para-aminobenzoic acid (PABA). Two other
members are folic acid and cyanocobalamin (F-12). Yeast and liver are
natural sources of most of these vitamins."

2) Another one is if vegetable derived folic acid is used in enriching
grain products like cooking rice,or is animal liver used instead?
Neither, Folic Acid (synthetic form) is added to grain products
because it is less easily damaged by cooking and and it is more more
readily available in the digestive tract.
"Although folate (the natural form) and folic acid (the synthetic form)
are very similar in structure, folate is not as stable as folic acid -
it is more easily damaged by cooking and processing. Also, food
folates need to be broken down in the digestive system before the body
can absorb them. This means that folic acid is absorbed more
efficiently than the natural form of the vitamin."
http://www.nutrition.org.uk/upload/Consumer%20booklet%20folate%20final.pdf
"Folate is a water-soluble B vitamin that occurs naturally in food.
Folic acid is the synthetic form of folate that is found in
supplements and added to fortified foods [1].
In 1996, the Food and Drug Administration (FDA) published regulations
requiring the addition of folic acid to enriched breads, cereals,
flours, corn meals, pastas, rice, and other grain products [6-9].
Since cereals and grains are widely consumed in the U.S., these
products have become a very important contributor of folic acid to the
American diet. The following table suggests a variety of dietary
sources of folate."
Table 1: Selected Food Sources of Folate and Folic Acid [5]
* Items marked with an asterisk (*) are fortified with folic acid as
part of the Folate Fortification Program.
"However, the folic acid fortification program, which was initiated in
1998, has increased folic acid content of commonly eaten foods such as
cereals and grains, and as a result most diets in the United States
(US) now provide recommended amounts of folate equivalents [14]."
http://ods.od.nih.gov/factsheets/folate.asp
Here's a pretty good history -
Epi in Action
http://www.whsc.emory.edu/_pubs/ph/spring01/epi.html
3) And what about the "Acid" in the Folic Acid, does that mean it has
some alcoholic acidity in it? is folic acid fermented somehow?
I would think that the word "acid" comes from "pteroic acid", a
constituent of folic acid.
"pteroic acid (pte·ro·ic ac·id) (t[schwa]-ro˘ik) a constituent of
folic acid consisting of p-aminobenzoic acid linked to a substituted
pteridine by a methylene bridge."
http://www.mercksource.com/pp/us/cns/cns_hl_dorlands.jspzQzpgzEzzSzppdocszSzuszSzcommonzSzdorlandszSzdorlandzSzdmd_p_41zPzhtm#1088412
Yes, it is produced by fermentation.
Fabricating folic acid
"Manufacturers create folic acid via numerous fermentation and
purification steps to meet U.S. Pharmacopoeia (USP) or European
Pharmacopoeia (EP) monograph requirements. Once it is fermented and
purified, folic acid becomes a fine chemical, in the form of a fluffy
yellow-orange powder. It is water soluble and very stable in
low-moisture heat. Acidity is the most vexing problem for folic acid
as it degrades easily in low-pH products (below pH 5)."
