Variation in human milk fat globules (HMFGs) and the association with fatty acid (FA) composition during lactation was investigated. Human milk samples (n = 134) from six healthy Chinese mothers were collected every day between 3 and 30 days postpartum, and the size distribution of HMFGs and FA composition in samples were investigated. The results indicated that mean HMFG size increased from 3.77 +/- 0.95 to 5.09 +/- 0.88 mu m during lactation. A significant increase was observed in the size of HMFGs and fat content in human milk samples from day 3 to day 10 postpartum. Colostrum samples showed higher contents of medium-chain fatty acids, very-long-chain fatty acids, and saturated fatty acids than mature milk. (C) 2019 Elsevier Ltd. All rights reserved.
