Abstract
Breast milk is the first and best food for the baby and the natural source of all the nutrients needed by the infant to grow and move. At present, local and international markets are full of milk products and alternatives milk products. The aim of this study was to find the differences between the infant formula and breast milk in the presence and percentages of fatty acids during the period of lactation. A total of 240 samples of healthy mothers (ages 18-33 years) which had an infants aged 3-11 months were collected voluntarily, the samples were collected daily and five days per week. A representative sample of the week was taken to measure the presence and percentages of fatty acids by GC mass. The results of fatty acids for the mother sample for the period less than six months were shows (Capric, Lauric, Myristic, Palmitic, Palmitoleic, Stearic, Oleic, Linoleic and Margaric acid 1.41, 1.49, 0.86, 2.59, 0.85, 0.64, 9.09, 10.3, 0.85%), while the infant formula was (IF1 = Linoleic 14.75 %, Oleic 5.11%, Stearic11.39%, Palmitic 3.9%, Myristic 1.04%, Lauric 2.71% and Capric 0.52 %, IF2 = Capric 1.44%, Lauric 9.44%, Myristic 3.34%, Palmitic 5.86%, stearic 1.92%, Oleic 12.51% and Linoleic 6.37%, IF3 = Capric 0.7%, Lauric 1.39%, Myristic 0.53%, Palmitic 4.51%, stearic 0.71%, Oleic 3.73% and Linoleic 2.44% ). While it were the results of breast milk from fatty acids in the period after six months were as follows (Capric 0.84%, Lauric 3.14%, Myristic 2.94%, Palmitic 5.33%, Palmitoleic 0.2%, Stearic 1.8%, Oleic 6.23%, Linoleic 7.06%, Margaric acid 1.16%), the results of the infant formula varied for the same period(IF4 = capric 0.84%, Lauric 3.52%, Myristic 0.94%, Palmitic 5.12%, Palmitoleic 3.64%, Stearic 1.06%, Oleic 5.62% and Linoleic 2.95% IF5 = Capric 0.97 %, Lauric 4.59 %, Myristic 0.74%, Palmitic 3.42 %, Palmitoleic 18.44 %, Undecanoic acid 4.53 %, Oleic 5.13 %, Linoleic 3.02 %, Stearic 1.18 %, Margaric acid 1.64 % and Arachidic acid 0.88 %, IF6 = Lauric 0.5%, Myristic 0.55%, Palmitic 2.83%, Palmitoleic 20.1%, Sebacic 1 %, Arachidic acid 0.98%, Linoleic 1.49 %, Stearic 1.1 % ). The study showed that the earliest infant formula was (IF5) in terms of the fatty acids presence for the second period compared to breast milk, but in terms of ratios did not find a match between breast milk for the periods before and after six months, as well as between breast milk and infant formula.
