Summary: This study investigates the structure, physico-chemical and functional properties of yellow lupin isolate protein obtained by different processes. The defatting process modifies the physical, structural and functional characteristics of lupin protein isolates. The defatting process improves the emulsifying stability and changes the particle size and viscosity of the protein isolates.

Summary: The polyphenolic compounds from the seed coat of walnuts have been found to hinder the hydrolysis of walnut protein and enhance the inhibition of acetyl-cholinesterase (AChE). Among these compounds, FQ shows the highest inhibitory capacity by interacting with amino acid residues in AChE. The combination of chlorogenic acid and FQ exhibits synergistic effects on AChE inhibition.

Summary: This study investigated the uptake, translocation, metabolism, dissipation, and dietary risks of tolfenpyrad in hydroponic romaine and amaranth plants. The results showed that tolfenpyrad was easily absorbed and accumulated in the roots of both vegetables, with basipetal translocation occurring in romaine but not in amaranth. Six metabolites and three metabolic pathways were proposed. Tolfenpyrad dissipated quickly, posing an acceptable risk to human health.

Summary: This study describes the use of improved pre-column methods combined with gradient elution C18-chromatography and DAD and FLD detection for the analysis of tocotrienols, tocopherols, alpha-tocopheryl acetate, and cholesterol in various biological samples. The quantification of tocotrienols and tocopherols in oils can be performed using C18-chromatography without saponification. Saponification followed by C18-chromatography is required for the quantification of tocopherols in milk. Esterification of hydroxyl group of tocopherols allows their satisfactory separation. The combination of esterification, C18-chromatography, and DAD monitoring provides a suitable analytical tool for the quantification of beta- and gamma-forms of tocopherols in biological samples. The original C18-chromatographic methods used in this study are precise, accurate, repeatable, and have low limits of detection (<10 ng/mL) and quantification (<27 ng/mL) for the analyzed tocopherols and cholesterol.

Summary: Nitrogen-doped carbon nanodots (N-CNDs) were synthesized using glutathione, and a dual-signal sensing platform for the rapid analysis of Cr(VI), Ag(I), and HCHO was successfully constructed. The platform utilized the fluorescence characteristics of N-CNDs and the fluorescence resonance energy transfer effect, demonstrating excellent selectivity and practical applicability.

Summary: Chitosan-pectin emulsion-filled hydrogel (EFH) was developed to enhance the bioaccessibility of lipophilic bioactive compounds through intestinal delivery. The EFH, prepared without crosslinking agents, demonstrated improved mechanical strength and compactness with higher pectin concentration. It retained the emulsion at pH 2.0 and released it at pH 7.4, resulting in enhanced release of free fatty acids and improved bioaccessibility of curcumin.

Summary: Horse's milk, with its high nutritional value and low allergenic proteins, could be a substitute for cow's milk in infant consumption. A proteomic method was used to identify and compare milk fat globule membrane (MFGM) and whey proteins from different horse breeds. The study found differences in protein composition and functionality, which could support the development of formulas more suitable for human infants.

Summary: This study evaluated the pesticide residues in commercial bee pollen samples and found different types of pesticides, including plant protection chemicals and veterinary treatments. Although pesticide concentrations exceeding the maximum residue limit were detected in some samples, the risk assessment showed that consuming these bee pollen does not pose an unacceptable risk.

Summary: A transfer learning method (TCA-LSSVR) has been developed to accurately assess industrial paraffin contamination levels in rice. The algorithm integrates transfer component analysis (TCA) with domain adaptive capabilities to produce accurate estimates, which have been validated through experiments with rice from different regions and industrial paraffins.

Summary: This study investigated the effects of Staphylococcus inoculation on protein degradation and taste of dry-cured bacon. It was found that co-inoculation of Staphylococcus xylosus and Staphylococcus vitulinus improved the taste attributes of the bacon. High residual activities of proteases accelerated protein degradation, and quantitative proteomic analysis revealed down-regulated proteins in the co-inoculated group. Morphological changes of structural proteins were confirmed by atomic force microscopy. The accumulation of glutamic acid, alanine, and lysine was identified as the main contributor to the taste improvement.

Summary: This study explored the sensory characteristics, metabolites and antioxidant capability of aged Jinhua white tea, and revealed the transformation mechanism of these characteristics during the long-term aging process. The unique flavor of aged Jinhua white tea was dominated by mellowness, smoothness, a fungus fragrance, and a stale flavor. The high content of theabrownine, soluble sugar, flavonoids and aroma components contributed to the formation of the unique flavor, and their content significantly increased during the long-term aging process.

Summary: This study investigated the molecular weight distribution of proteins in bovine milk, human milk, and infant formula using exclusion chromatography. It was found that infant formula contains a higher proportion of macromolecular proteins compared to human or bovine milk. Significant differences in protein molecular weights were also observed between human milk and bovine milk.
