This study aimed to prepare infant formula concentrates (IF) that simulate human milk fat globule (HMFG) composition, size, and distribution. The results showed that IF4 had the closest size distribution and interface with HMFG.
This study aims to prepare infant formula concentrates (IFs) simulating human milk fat globule (HMFG) composition, size and distribution. Mixed plant oil (21.3% palm oil, 2.8% flaxseed oil, 2.6% soybean oil, 29.9% rapeseed oil and 43.4% corn oil) and concentrated whey protein were applied to mimic triacylglycerols and phospholipids in HMFG respectively. IF1-IF6 were produced by different homogenization pressures or physically mixed with different proportions. IF4, prepared with 95% IF1 (4.29 mu m), 1% IF2 (0.497 mu m) and 4% IF3 (9.43 mu m), showed a mean particle size of 3.96 mu m and 49.77% milk fat globule membrane protein, and had the closest size distribution and interface with HMFG. The prepared IFs showed good stability with the Turbiscan stability index (IF6 (1.75)
