Demand for infant formula, as an alternative to human milk, is
growing because of inability of mothers to breast feed. Therefore,
infant formula must meet the nutritional requirements of growing
infants as close as possible to avoid serious health problems for the
survival of newborn infants. Infant foods should contain a level of
omega-3 fatty acids and arachidonic acid and shouldn’t contain
trans fatty acids (Chapkin, 2000). We have analyzed samples of
baby food enriched with arachidonic acid and docosahexaenoic
acid and the results show that the sample contains 0.2% of arachidonic
acid and 0.2% of docosahexaenoic acid.
In vegetable oils fatty acids with an even carbon number are
dominant, whereas in oils and fats of animal origin with odd carbon
number FAs are present. Also, fats and oils of animal origin
contain lot of polyunsaturated fatty acids (PUFA). That makes analyzing
the fatty acid profile even more complex. In Fig. 3 our chromatograms
of extracted fat from different tuna samples are shown.
