چکیده

Background: Lipid oxidation is a major factor affecting the chemical stability and shelf life of processed meat products during frozen storage. Natural plant oils rich in bioactive compounds have gained attention as effective alternatives to Mentha longifolia antioxidants. These compounds can reduce oxidative deterioration and improve product quality.

Objective: This study aimed to evaluate the effect of different concentrations of Mentha longifolia oil on the chemical properties and oxidative stability of processed burger patties during frozen storage.

Materials and Methods: Crude Mentha longifolia oil was extracted using a Clevenger apparatus. Burger samples were divided into four treatments: control (T1) without oil addition, and T2, T3, and T4, each supplemented with 1, 2, and 3 g of Mentha longifolia oil, respectively. Chemical analyses were conducted before freezing and during 60 days of frozen storage at −18 °C, with testing performed twice per month. Fatty acid composition and flavonoid profiles were determined using GC–MS and HPLC, while oxidative stability was evaluated by measuring free fatty acids (FFA), peroxide value (PV), and thiobarbituric acid (TBA).

Results: Mentha longifolia oil exhibited a high content of essential fatty acids and 38 identified flavonoid compounds, dominated by caffeic acid, apigenin, quercetin, and 4-hydroxy derivatives. No significant differences (P ≥ 0.05) were observed among treatments before freezing. During frozen storage, oxidative indices increased in all samples; however, oil-treated burgers showed significantly lower FFA, PV, and TBA values, with treatments T3 and T4 recording the lowest values compared to the control.
