As established by Regulation EU number 61/2011, the presence of mildly deodorized oils in EVOOs is accompanied by a parallel increment of methyl and ethyl esters of fatty acids (FAMEs and FAEEs
) in treated oils.
Transesterification of Oil to FAEE
. :H NMR spectrum of the a-methylene groups of the long-chain ethyl esters should present a signal in the region between 4.00 and 4.40 ppm as quadruplet (characteristic of ethyl esters), while the spectrum of oils showed signals associated with the [alpha]-methylene groups of the triacylglycerides (doublet of doublets) .

are formed from endogenous free fatty acids and ethanol by specific and nonspecific enzymes in blood and several tissues (19).
It is equally important to double-check with your oil supplier whether they are supplying oils that contain FAME (or, even worse, FAEE
) without you being aware of it.
Figure 2 shows the time course of the FAEE
content and decomposition for these conditions.
A minor pathway is non-oxidative esterification with fatty acids to fatty acid ethyl esters (FAEEs
This paper presents an overview of FASD, reviews FAEE
screening, and then focuses upon the ethical and legal challenges inherent in the new screening technologies as they relate to providing care to women and their infants.
The enzymatic formation of FAEE
after alcohol consumption was first discovered in 1981; and, since then, research has shown the presence of FAEE
in many biological tissues and fluids, including blood, various post-mortem specimens, meconium (for the determination of fetal alcohol exposure), and hair.
In a recent study a team of scientists monitored around 40 drinkers and teetotallers, and showed that FAEE
levels in hair can distinguish between light and heavy drinkers.
If the formula written in the paper is read at its faee
value then inserting estimated TFR equal to 5.06, the CBR would be 28.72 and if CBR equal 35.64 estimated through this equation by the authors is considered as correct, then inserting this value in the suggested regression equation, the multiplier of TFR would be 7.0 and not 0.0070.
