摘要:
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 μm), 1% IF2 (0.497 μm) and 4% IF3 (9.43 μm), showed a mean particle size of 3.96 μm 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)
