Fatty acid composition and fat content of some infant formulas commercially available in Sudan and its comparison with fatty acid compositions of mature breast milk from different parts of the world
Abstract
This study was designed to evaluate fat content and fatty acid composition of some infant formulas commercially available in Sudan and its comparison (from available literatures) with fatty acid compositions of mature breast milk from different parts of the world. The fat content of only four commercial formulas was in agreement with the values declared by the manufacturer. Data of saturated fatty acids shows that the palmitic acid (C16:0) was the principle saturated fatty acid for almost all formulas. It was observed that none of the studied formulas for infants contained the fatty acids pentadecyclic acid (C15:0), margaric acid (C17:0), behenic acid (C22:0) and lignoceric acid (C24:0). Oleic acid (C18:1) was found to be the most abundant mono unsaturated fatty acid in formulas. Absence of the mono unsaturated fatty acids C17:1 (cis-10) fatty acid and erucic acid (22:1) was observed for all formulas. Linoleic acid (C18:2), an omega-6 fatty acids in studied formulas ranged from 8.1-17.55%. Alpha-linoleinic acid (C18:3), an omega-3 fatty acids ranged from 0.2-2.21%. In only one starting formula (HM1), one follow up formula (HM2) and one weaning food (HM3) the ratio of C18:2/ C18:3 was less than 10:1. Percentage of palmitic acid (C16:0) was found to be higher in studied follow up and weaning foods than the previously reported mature breast milk. It has been depicted that the oleic acid content of studied infant formulas were higher than mature breast milk. Alpha linolenic acid percentage in both mature breast milk and infant formulas were much lower than linoleic acid. Based on data of this study and previous investigation on this area, it is recommended that infant formulas should be fortified with long chain polyunsaturated fatty acids.
