INFAT®PLUS, the innovative fat blend developed by Advanced Lipids, is designed to be closer in structure to Chinese human milk fat. It complies with GB standard 30604-2015 for OPO and has all the benefits of high sn2 palmitate fat – making it the perfect fit for Chinese infant formula.
Human milk provides the optimal nutrition for infants. It offers perfectly balanced nutrition, naturally meeting the needs of growing infants in the first months of life. In human milk, and in most infant formulas, the fat provides about 50% of the energy the newborns require for proper development and growth. More than 98% of this fat is in the form of triglycerides (TG), a common fat molecule comprised of fatty acids attached to a glycerol backbone. The fatty acids are specifically positioned to certain locations called sn1, sn2 and sn3 on the glycerol backbone.
In human milk, palmitic acid (C16:0) the predominant saturated fatty acid, is usually bound, 70-80% of it, to the sn2 position on the glycerol backbone. This specially structured TG is called sn2 palmitate. sn2 palmitate is highly conserved across populations, found in mothers all over the world, regardless of their nutritional diet, ethnicity or age, suggesting that it may serve an important function.
Oleic acid (18:1n-9) is the major unsaturated fatty acid in human milk and is mostly esterified at the TG sn1,3 positions (outer). With palmitic and oleic acid being the most abundant fatty acids in human milk, the TGs with the structure Oleic-Palmitic-Oleic (OPO, 18:1n-9-16:0-18:1n-9) are among the major TG species in human milk and represent an estimated ~12% of total TG species.
However, recent data collected from human milk studies in China [1-3] suggests that in China the major TG species found is Oleic-Palmitic-Linoleic (OPL, 18:1n-9-16:0-18:2n-6), and this contrasts with the TG profile in human milk collected in other places, such as Finland , Spain  or Denmark , where the level of OPO is higher than OPL. The basis for this difference has not been fully evaluated yet, but may be related to nutrition.
In most infant formula produced today, the fat component is based on vegetable oil, where most of the palmitic is positioned on sn1 or sn3, and not on sn2. INFAT® the specially structured TG with palmitic bound to the sn2 position (OPO) was developed for infant formula, so when it is added to infant formula, it elevates the sn2 palmitate so it is closer to human milk.
INFAT®PLUS, the innovative fat blend developed by Advanced Lipids, is designed to be closer in structure to Chinese human milk fat in all major TG species. INFAT®PLUS complies with GB standard 30604-2015 for OPO and has all the benefits of enriched sn2 palmitate fat. This makes INFAT®PLUS the best choice for Chinese infant formula.
