Bioactive Collagen Peptides in Veterinary and Biomedical Science—Part I: Molecular Identity, Gastrointestinal Bioavailability, and Receptor-Mediated Signaling, with Relevance to the Bile Acid Axis

The strongest current evidence supports specific collagen fragments for relieving joint disease in dogs and horses, and a newly recognised link between collagen fragments, gut bacteria, and bile that may explain effects on metabolism and the liver is described.

Leaching of postharvest pesticides from lemon fruits into liquid foodstuffs.

The transfer of postharvest fungicides from citrus peel into foods is a poorly characterised exposure pathway. This study assessed the migration of imazalil (IMZ), thiabendazole (TBZ) and pyrimethanil (PMT) from lemon peel into altogether 25 commonly consumed beverages and soups under everyday use conditions. All fungicides were detectable in every matrix. Leaching efficiencies spanned more than three orders of magnitude, ranging from approximately 1 to 540 ‰ of the original residue load. PMT consistently showed the highest migration across matrices. Alcohol content moderately increased PMT transfer, whereas higher dry matter reduced TBZ and PMT migration; temperature showed no consistent effect. These findings demonstrate that matrix composition strongly influences residue mobility. Although resulting concentrations remained well below regulatory limits, matrix-dependent leaching may contribute to low-level consumer exposure, when untreated lemon peel is frequently used in foods or drinks.
