Medium- and long-chain triacylglycerol in human breast milk and association with maternal dietary patterns
This study aims to investigate the influences of maternal dietary patterns on the triacylglycerol (TAG) composition, particular medium- and long-chain triacylglycerol (MLCT) in human breast milk. A total of 180 Chinese human breast milk samples were collected and divided into three dietary patterns groups accounting to semi-quantitative food intake frequency questionnaire and a 24-h dietary recall. The 180 samples were from 121 mothers in Nanjing, all of whom were mature milk (1 month postpartum and 3 months postpartum). Using high performance liquid chromatography combined with quadrupole time-of-flight mass spectrometry, 108 TAGs were identified and quantified. In breast milk samples, MLCTs accounted for 25.76% (median of 24.63%; 95% CI: 24.60, 26.92) of the total TAGs. In human breast milk, the main type of MLCT is the triacylglycerol with one medium-chain fatty acid and two long-chain fatty acids (MLL type) which accounted for ~81% of total MLCTs. Among the molecular species of MLCT, O-P-La and O-L-La are the two most abundant configurations in MLCT (2.28% and 2.17% of total TAGs, respectively). MLCT in breast milk was positively correlated with the energy supply ratio of carbohydrates (p = 0.205), which was significantly higher than that of the other two groups (p = −0.150 and −0.232).
期刊介绍：
The Journal of the American Oil Chemists’ Society (JAOCS) is an international peer-reviewed journal that publishes significant original scientific research and technological advances on fats, oils, oilseed proteins, and related materials through original research articles, invited reviews, short communications, and letters to the editor. We seek to publish reports that will significantly advance scientific understanding through hypothesis driven research, innovations, and important new information pertaining to analysis, properties, processing, products, and applications of these food and industrial resources. Breakthroughs in food science and technology, biotechnology (including genomics, biomechanisms, biocatalysis and bioprocessing), and industrial products and applications are particularly appropriate.
JAOCS also considers reports on the lipid composition of new, unique, and traditional sources of lipids that definitively address a research hypothesis and advances scientific understanding. However, the genus and species of the source must be verified by appropriate means of classification. In addition, the GPS location of the harvested materials and seed or vegetative samples should be deposited in an accredited germplasm repository. Compositional data suitable for Original Research Articles must embody replicated estimate of tissue constituents, such as oil, protein, carbohydrate, fatty acid, phospholipid, tocopherol, sterol, and carotenoid compositions. Other components unique to the specific plant or animal source may be reported. Furthermore, lipid composition papers should incorporate elements of yeartoyear, environmental, and/ or cultivar variations through use of appropriate statistical analyses.
