Mate extract (Ilex paraguariensis A.St.-Hil.), generally recognized as safe (GRAS by the FDA), was used as broilers feed additive to improve meat quality and shelf-life. Addition of mate extract to broilers feed affects metabolic pathways related to endogenous peptide derived antioxidants in muscle tissue. Chicken meat from broilers supplemented with lower levels of mate extract (250-500 mg per kg of feed) shows increased content of β-alanine, anserine, and carnosine, improving overall quality and oxidative stability of chicken meat. Details are presented in the Article Mate as Dietary Supplement for Broiler Chickens: Effect on the Metabolic Profile and Redox Chemistry of Meat by Caroline Ceribeli, Andressa de Zawadzki, Aline M. C. Racanicci, Luiz A. Colnago, Leif H. Skibsted and Daniel R. Cardoso on page 2266.

Old Drawback on Azlactone Formation Revealed by a Combination of Theoretical and Experimental Studies

Pedro P. de Castro; Gabriel M. F. Batista; Danielle L. J. Pinheiro; Hélio F. dos Santos; Giovanni W. Amarante

How to cite this article

 

Novel insights in the formation of different 2-substituted azlactone heterocycles. The formation of 2-aryl and 2-alkyl azlactones are favored by a sum of both kinetic and thermodynamic factors, while the cyclization of 2-alcoxy azlactones is less favored.
