The efficiency of the absorption and digestion of lutein in infant formulas (IFs) is remarkably lower than that in human milk. This work compared the simulated dynamic digestive characteristics of lutein in three stages of human milk and six IFs, with a special emphasis on how polar lipids affect lutein digestion. Compared with colostrum (CM), IF2 had a significantly higher lutein loss rate but significantly lower micellarization and bioaccessibility rates. In CM, the morphology of milk fat globules (MFGs) remained visible after digestion; the phospholipid globular membrane structure can be observed after 180 min of intestinal digestion, and MFGs remained in a spherical form in micelles. Lipidomic analysis precisely quantified 18 significantly different lipids, including cholesterol, phosphatidylcholine, phosphatidylserine, phosphatidylinositol, phosphatidic acid, and phosphatidylglycerol, between CM and IF2 micelles, suggesting that these lipids may influence the micellarization of lutein. In summary, polar lipids play an important role in the protection of lutein and the facilitation of lutein micellarization. These findings also provide a certain reference for the adjustment of IF formulations.

The mammary gland, which primarily develops postnatally, undergoes significant changes during pregnancy and lactation to facilitate milk production. Through the generation and analysis of 480 transcriptomes, we provide the most detailed allelic expression map of the mammary gland, cataloguing cell-type-specific expression from ex-vivo purified cell populations over 10 developmental stages, enabling comparative analysis. The work identifies genes involved in the mammary gland cycle, parental-origin-specific and genetic background-specific expression at cellular and temporal resolution, genes associated with human lactation disorders and breast cancer.

Recent years have seen advances in clinical biochemistry of domestic animals which have highlighted comparative differences between species and have also identified fundamental aspects of the biochemical mechanisms in physiological conditions and disease, that have implications across species, including human, health and welfare. From investigations in diverse species using biochemical, immunological, proteomic and metabolomic approaches a series of species particularities and unexpected results for some biomarkers have been made. These observations cover (1) the differences between species in the acute phase protein (APP) response to infection and inflammation; (2) the non-hepatic synthesis and release in the mammary gland, adipose tissue and intestine of APP (3) the response of haptoglobin (HP) as a biomarker for stress; (4) observations in non-mammalian species related to hemopexin and HP; (5) the response of bile acids in milk to mastitis; (6) barley serine protease inhibitors being identified in bovine faeces; (7) alkaline phosphatase being present in bovine nasal secretion; (8) saliva findings with analytes such as adenine deaminase showing different activity between saliva and serum and a detergent-like surfactant protein, latherin being found in equine saliva and sweat and (9) serum enzymes and selective muscle protein reaction of Atlantic salmon as an example of the differences in biochemistry between terrestrial and aquatic species.

Ethnic fermented foods represent a significant repository for discovering novel probiotic entities. These fermented foods, entrenched in indigenous practices, have conserved a distinct microbiota through generations. Exploration of these fermented foods could yield microbial consortia capable of transforming human health.

Introduction: Dependent older adults in residential aged care are at increased risk of inadequate micronutrient intakes. Knowledge of dietary intakes in this group is needed to inform clinical decision making and guide nutrition policy and menu planning. This study aimed to determine the usual intake and food sources of micronutrients of New Zealand aged-care residents.

There is a need for sustainable food production and processing that reduces resource use and increases the availability of nutritious, innovative, and sustainable food. A coordinated, multisectoral approach across the food supply chain is essential to address global food and nutrition insecurity. The dairy industry produces abundant bioactive compound streams that can be examined for their valuable functionalities.
