Antioxidant Activity and Acute Oral Toxicity of Soursop (Annona muricata L.) Leaf and Its Effect on the Oxidative Stability of Mexican Hairless Pork Patties.

The oxidation of meat and meat products can be delayed or mitigated through the use of natural antioxidants. Soursop leaf extracts have potential as a natural additive in meat products, offering a rich source of antioxidants. However, the impact and safety of incorporating soursop leaf extracts on the oxidative stability of meat products are not yet well understood. This study evaluated the antioxidant activity and acute oral toxicity of hydroalcoholic extracts from soursop leaves, as well as their effects on color and the oxidative stability of lipids and proteins in chilled Mexican Hairless pork patties. The results suggest that hydroalcoholic soursop leaf extracts may serve as a safe source of bioactive compounds with antioxidant properties, suitable for use as an additive in meat and meat products to reduce color loss and lipid oxidation, with a lesser effect on protein oxidation.
