“…The total content of MLCT and UPU in breast milk was not affected by dietary structure, indicating that the total content of MLCT and UPU in breast milk was relatively stable. Our previous study (Yu et al, 2022b) also pointed out that the sum of MLCT and UPU was not affected by region and lactation and remained stable. By changing the proportion of the three major nutrients in the diet, changes in the TAG composition of breast milk can be achieved, especially MLCT type TAG.…”

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-hour dietary recall. 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 TAGs esterified 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, O-L-La, and O-L-M are the three most abundant configurations in MLCT (2.28%, 2.17%, and 2.01% 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).

“…The saturation and carbon chain length of FA are important for TAG, they can further influence the physical property of MF, such as melting point and crystal texture, and they also provide more nutritional information (Martini et al., 2012; Tzompa‐Sosa et al., 2016; Zhao et al., 2018; Wang et al., 2019). Based on the saturation of FA, the TAG of MF was classified into four groups: S 3 (SSS) with three SFAs; U 3 (UUU) with three UFAs; S 2 U (SSU and SUS) with one UFA and two SFAs; and SU 2 (SUU and USU) consisted of one SFA and two UFAs (Yuan et al., 2019; Yu et al., 2022). It was evident that the TAG with different saturation of FA in the residue was not changed significantly compared with those of AMF and distillate (Tables 3 and 4).…”

Fractionation is important for the application of milk fat (MF). In this study, the contents of fatty acid (FA) and triglyceride (TAG) of MF and its fractions distilled by short-path molecular distillation (SPMD) were detected. The results showed that a total of 19 FAs and 109 TAG molecular species were detected. Moreover, the short-chain saturated FA, medium-chain saturated FA, low-molecular-weight TAG, medium-molecular-weight TAG, S 3 (TAG molecular species with three saturated FAs) and L 2 S (TAG molecular species with two long-chain FAs and one short-chain FA) were easily accumulated in the distillate, and the percentage of these components all increased first and then decreased during the whole distilling process. Compared with the distillate, polyunsaturated FA (PUFA) and high-molecular-weight TAG (HMW-TAG, with the carbon numbers: 41-54 and molecular weight: 704-888) were enriched in the residue, and the increasing ratio of PUFA and HMW-TAG was 393.75% and 8.58% respectively. Further analysis showed that the 16:0/4:0/16:0, 16:0/4:0/14:0, 16:0/12:0/4:0, etc. were the discrepant TAG molecular species during SPMD. Therefore, these results demonstrated that different fractions of MF could be obtained by adjusting the fractionation temperature, and it also would provide more important theoretical guidance for regulating MF fractionation, enriching the nutritional information of MF fractions.

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.
