Silver nanoparticles (AgNPs) are increasingly used in various consumer products and industrial applications, raising concerns about their environmental impact on aquatic ecosystems. This study investigated the physicochemical stability, trophic transfer, and toxic effects of citrate-coated AgNPs in a freshwater food chain including the diatom Cyclotella meneghiniana and the gastropod Lymnaea stagnalis. AgNPs remained stable in the exposure medium, with a minimal dissolution (<0.

The enhanced bioavailability of quercetin (Qr), which has low absorption, may have beneficial effects on human health. This study aimed to elucidate the effects of simultaneous pectin ingestion on the absorption and antioxidant activity of Qr. Qr concentrations in the plasma and urine of rats fed Qr + cellulose or Qr + pectin diets were determined, and thiobarbituric acid reactive substances (TBARS) in oxidized low-density lipoprotein (LDL) were measured.

This study aimed to explore the effects of different brining times on the sensory, physicochemical properties, and volatile organic compounds (VOCs) of marinated grass carp (MGC). The results showed that different brining time changed the sensory quality, color and texture. The moisture content increased significantly with the extension of brining time, while the salt content, protein content, thiobarbituric acid reactive substances (TBARS), and total volatile basic‑nitrogen (TVB-N) decreased ( 0.
