Re: fatty acid profile of oils

[Guest guest]

hey Lynn...

Just my $0.02, but I'd question any book that gave percentages of

fatty acids in anything but ranges...each individual pressing (or

whatever) of oil will have slightly different results!

Other than that, I can't really answer your question, because all the

fatty acid profiles I've come across lately list the fatty acids by

number of carbon atoms or something like that and I'm too tired after

writing my exam tonight to try and decipher it! *LOL*

According to the USDA Nutrient Database for Standard Reference, Release

14,

http://www.nal.usda.gov/fnic/cgi-bin/nut_search.pl

Soybean Oil contains

Myristic Acid = 0.1%

Palmitic Acid = 10.3%

Palmitoleic Acid = 0.2%

Stearic Acid = 3.8%

Oleic Acid = 22.8%

Linoleic (Omega 6) Acid = 51%

Linolenic (Omega 3) Acid = 6.8%

Gadoleic Acid = 0.2%

>evening primrose oil's profile on the chart looks like this:ÿ

>linoleic 70.6%, oleic 11.2%, linolenic 9.4%, palmitic 6.1%, stearic

>1.6%, palmitoleic 0.2%, other 0.9%.

Evening Primrose Oil is not found in the USDA database, however, in

" Primary Ingredients " , written by O'Lenick, Steinberg,

and Ken Klein,

http://www.zenitech.com/primary_ingredients_zenitech.pdf

The authors provide this fatty acid breakdown:

Palmitic Acid = 6%

Stearic Acid = 2%

Oleic Acid = 8%

Linoleic (Omega 6) Acid = 75%

Linolenic (Omega 3) Acid = 9%

As Jules implies in her earlier message, the chemical composition of

natural ingredients is depending on many enviromental factors and

processing variables. And so, the numbers provided by the USDA and the

authors of " Primary Ingredients " are " ball park " numbers.

The USDA numbers are based on one or more analyses.

For your purposes, I think that the data in your book is probably good.

I'd compare some of the oils found in your book with the numbers

provided by the USDA.

Here's the nomenclature breakdown that I've been using:

C4:0 = Butyric Acid

C6:0 = Caproic Acid

C8:0 = Caprylic Acid

C10:0 = Capric Acid

C12:0 = Lauric Acid

C14:0 = Myristic Acid

C14:1 = Myristoleic Acid

C15:0 = Pentadecanoic Acid

C16:0 = Palmitic Acid

C16:1 = Palmitoleic Acid

C16:2 = Hexadecadienoic Acid

C16:3 = Hexadecatienoic Acid

C16:4 = Hexadecatetraenoic Acid

C17:0 = Margaric Acid

C17:1 = Margroleic Acid

C18:0 = Stearic Acid

C18:1 = Oleic Acid

C18:2 = Linoleic (Omega 6) Acid

C18:3 = Linolenic (Omega 3) Acid

C18:4 = Octadecatetraenoic Acid

C20:0 = Arachidic Acid

C20:1 = Gadoleic Acid

C20:2 = Eicosadenoic Acid

C20:4 = Eicosatetraenoic Acid

C20:5 = Eicosapentaenoic (Omega 3) Acid

C22:0 = Behenic Acid

C22:1 = Erucic Acid

C22:5 = Docosapentaenoic Acid

C22:6 = Docosahexaenoic (Omega 3) Acid

C24:0 = Ligniceric Acid

So you want fatty acid profiles?

Check out these webpages

http://www.bcs.uni.edu/abil/htmlpages/researchresources/statisticaldata/

StatTable1.cfm

http://www.bcs.uni.edu/abil/htmlpages/researchresources/statisticaldata/

StatTable2.cfm

http://www.bcs.uni.edu/abil/htmlpages/researchresources/statisticaldata/

StatTable3.cfm

http://www.bcs.uni.edu/abil/htmlpages/researchresources/statisticaldata/

StatTable4.cfm

StatTable 1, 2 & 3 contain the most detailed analysis.

And yes, you can copy these fatty acids tables and paste them into

Excel. This may help if you want to sort the information.

Well worth a look.

Thanks Maurice - that saves me from having to ask about ricinoleic

acid, since it wasn't on your list. Hey, I'm a big castor bean oil

fan...what can I say!
