Oxidative damage is one of the main reasons for loss of quality in sheep and goat meat and meat products. Synthetic antioxidants are the current solution to stabilize oxidative process and extend the shelf life of such products; however, the negative impact on health may impose a risk to consumers. Natural antioxidants, extracted from several vegetable sources, have been considered an attractive alternative for this conflicting situation. Phenolic compounds are minor components in herbs, spices, tea and fruits that display potential application against the progression of lipid and protein oxidation and their consequences for meat quality, which can even overcome the protective effect of synthetic compounds. This review aims to discuss the mechanisms associated to lipid and protein oxidation and their implications on meat quality attributes and provides recent data regarding the application of natural antioxidants in sheep and goat meat products, which have a high susceptibility to oxidative processes compared to other red meats.

UI MeSH Term Description Entries
D008461 Meat Products Articles of food which are derived by a process of manufacture from any portion of carcasses of any animal used for food (e.g., head cheese, sausage, scrapple). Meat Product,Product, Meat,Products, Meat
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
D010936 Plant Extracts Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard. Herbal Medicines,Plant Extract,Extract, Plant,Extracts, Plant,Medicines, Herbal
