Being the dominant components in human milk fat (HMF), triacylglycerol (TAG) composition might be the best approximation index to represent the composing characteristics of HMF. In this study, TAG composition of HMF from different lactation stages was analyzed by RP-HPLC-APCI-MS, and the establishment of a model for the precise evaluation of human milk fat substitutes (HMFSs) based on TAG composition was indirectly realized by employment of fatty acid composition and distribution and polyunsaturated fatty acid (PUFA) and TAG compositions. The model was verified by the selected fats and oils with specific chemical compositions, and the results revealed the degrees of similarity of these fats and oils in different evaluation aspects reflected their differences in corresponding chemical composition with HMF. The newly established evaluation model with TAG composition as a comparison base could provide a more accurate method to evaluate HMFSs and might have some inspirations for HMFS production in the future.

Phenomic selection based on parental spectra can be used to predict GCA and SCA in a sparse factorial design. Prediction approaches such as genomic selection can be game changers in hybrid breeding. They allow predicting the genetic values of hybrids without the need for their physical production.

This study focused on evaluating the fractionation of pequi oil and modeling the process using solid-liquid equilibrium (SLE) theory. The pequi oil was comprehensively characterized, including its fatty acid (FA) and acylglycerol (AG) profiles, moisture content, acidity, carotenoid levels, and thermal behavior. Low acidity and partial acylglycerols content, along with its TAG profile (mainly OOP, POP, OOO and PPP) and melting behavior proved that, in fact, this oil is quite suitable for fractionation.

Oleaginous yeasts offer a promising sustainable alternative for producing edible lipids, potentially replacing animal and unsustainable plant fats and oils. In this study, we screened 11 oleaginous yeast species for their lipid profiles and identified Apiotrichum brassicae as the most promising candidate due to its versatility across different growth media.

Two dwarf bunt resistance QTLs were mapped to chromosome 6D, and KASP markers associated with the loci were developed and validated in a panel of regionally adapted winter wheats. UI Silver is an invaluable adapted resistant cultivar possessing the two identified QTL potentially associated with genes Bt9 and Bt10 and will be useful in future cultivar development to improve dwarf bunt resistance. Dwarf bunt, caused by Tilletia controversa, is a fungal disease of wheat that can cause complete loss of grain yield and quality during epidemics.

Increasing physical activity (PA) is recognised as an efficacious approach for preventing and treating cardiometabolic diseases. Recently, the composition of microorganisms living within the gut has been proposed as an important appropriate target for treating these diseases. Whether PA is related to faecal microbiota diversity and composition in humans remains to be ascertained.
