Regional and longitudinal dynamics of human milk protein components assessed by proteome analysis on a fast and robust micro-flow LC-MS/MS system.

An in-depth exploration of molecular composition of human milk could provide a scientific basis for the development of substitutes. The present study was conducted to analyze human milk proteins from 110 individuals from five regions of China and across three stages of lactation to investigate the change patterns. We developed a micro-flow liquid chromatography tandem mass spectrometry (μLC-MS/MS) system with data-independent acquisition (DIA) proteomics technology that can rapidly and stably characterize the human milk proteome.

Postpartum dietary intake, depression and the concentration of docosahexaenoic acid in mature breast milk in Wuhan, China.

: Docosahexaenoic acid (DHA, C22:6) is an important fatty acid in breast milk and is essential for infantile growth and cognitive development. However, the factors that affect the DHA concentration in breast milk have not been completely clarified. : This study aimed to characterize the composition of breast milk fatty acids and to identify maternal factors associated with breast milk DHA concentration in postpartum women in Wuhan, China.

Comparison of glycerophospholipid and sphingolipid in mature milk from different sampled regions in the Chinese human milk project (CHMP) study.

Milk phospholipids (PLs) are critical components of infant growth. This study aimed to discover PL in mature human milk (HM) from China (n = 201) and mainly assessed the effect caused by sampled regions. The average total PL concentration was quantified from 3.

Effects of polymerized goat milk whey protein on physicochemical properties and microstructure of recombined goat milk yogurt.

Goat milk whey protein concentrates were manufactured by microfiltration (MF) and ultrafiltration (UF). When MF retentate blended with cream, which could be used as a starting material in yogurt making. The objective of this study was to prepare goat milk whey protein concentrates by membrane separation technology and to investigate the effects of polymerized goat milk whey protein (PGWP) on the physicochemical properties and microstructure of recombined goat milk yogurt.

Regional similarities and differences in mature human milk fatty acids in Chinese population: A systematic review.

Maternal factors such as the diet can impact human milk fatty acid profiles. We hypothesized that mature human milk fatty acid profiles differ among regions of China. To test our hypothesis, we conducted a systematic review to calculate regional average contents of fatty acids and the statistical significance of regional differences in fatty acids.

Cofermentation of cellobiose and galactose by an engineered Saccharomyces cerevisiae strain.

We demonstrate improved ethanol yield and productivity through cofermentation of cellobiose and galactose by an engineered Saccharomyces cerevisiae strain expressing genes coding for cellodextrin transporter (cdt-1) and intracellular β-glucosidase (gh1-1) from Neurospora crassa. Simultaneous fermentation of cellobiose and galactose can be applied to producing biofuels from hydrolysates of marine plant biomass.
