Mechanochemically modified aluminosilicates for efficient oxidation of vanillyl alcohol

Pharmacokinetics of a single gavage dose of 14C-labeled dihydrocapsiate (10 mg/kg) were investigated in male rats. Maximal plasma concentration was achieved in 40 minutes and exhibited an apparent half-life of 2.4 hours. Excretion of radioactivity in the urine, feces, and expired air was 78.2%, 19.4%, and 0.5% of the dose, respectively. Highest tissue concentrations were achieved in the kidney, liver, and blood; the data indicate that radioactivity accumulation following daily exposure at a dose of 10 mg/kg body weight is unlikely. Radioactivity in the plasma was associated with metabolites and their conjugates, probably vanillyl alcohol, vanillic acid, glucuronide of vanillyl alcohol, sulphate of vanillyl alcohol, and sulphate of vanillic acid. These results suggest dihydrocapsiate is metabolized by hydrolysis in the gut, or esterase or other enzymes in the blood, and the metabolites were rapidly absorbed and converted to their conjugates in the liver and eliminated by the kidneys into the urine.

Polylactide (PLA)-based polymers, functionalized with biobased antioxidants, were synthesized, to develop an intrinsically active, biobased and potentially biodegradable material for food packaging applications. To achieve this result, phenolic antioxidants were exploited as initiators in the ring opening polymerization of l-lactide. The molecular weight, thermal properties and in vitro radical scavenging activity of the polymers obtained were compared with the ones of a PLA Natureworks 4043D, commonly used for flexible food packaging applications. The most promising synthesized polymer, bearing vanillyl alcohol as initiator (PLA-VA), was evaluated for active food packaging applications. Packaging with PLA-VA films reduced color and fat oxidation of salami during its shelf life.
