* I have the pleasure to announce that we have published the progress report on the Nutrition Indicators for Biodiversity - Food Composition - reporting 2012 (FAO, 2013)<http://www.fao.org/docrep/017/i3198e/i3198e.pdf>. It is found at http://www.fao.org/infoods/infoods/food-biodiversity/en/
We are pleased that some few countries took the time and effort and completed the form we sent out in December 2012 on compositional data on food biodiversity. They are acknowledged in the report. I also would like to thank all those to contributed to the data collection, compilation and checking which was a lot of work. [...][log in to unmask]

Dear Colleague
Most fatty acids in food are esterified to be water soluble; non esterified fatty acid may be present in foods as a consequence of ripening and due to  the lipase and microorganisms lypolitical effect.  As an example,  in ripened cheese, the non esterified fraction which  is only 2% is due to the action of the lypasa from milk and from cheese microorganisms during the ripening, they make free fatty acids that contribute to smell of the product. So data about fatty acids composition you can find in food composition databases/tables are mainly from fatty acids that were esterified in food.

Asunto: non-esterified fatty acid concentration

Hello:
  We got a request asking if we had anything on the non-esterified fatty acid concentration of foods.  Also, if anyone is working in this area.

Thank you,

David
