This study aims to examine employing ultrasound‐assisted extraction of bioactive components from Moringa oleifera leaves and apply them in beef patties preservation, as well as antioxidant and inhibitory activities and sensory qualities. The study included studying the chemical content and minerals of the M. oleifera leaves, preparation of aqueous and alcoholic extracts using an ultrasound device, then exploring the extraction yield. The results proved that the extraction yield by ultrasound using ethanol at 80% was the highest, reaching 19.22%. The total phenols in the ultrasonic extract with moringa leaves aqueous extract (AMEUS) amounted to 120,755 mg/mL. Since the AMEUS exhibited the highest value of 68.308 mg/mL calic acid – eight phenolic compounds discovered by HPLC – the total content of flavonoids was also calculated. The inhibitory and antioxidant effects of moringa leaf extracts are well documented. We monitored the changes in chemical indicators, such as the value of peroxide and thiobarbituric acid, as well as the percentage of free fatty acids and physical characteristics, such as water‐carrying capacity, pH, and pigments, for storage periods 0, 4, 8, and 12 days after adding AMEUS to beef patties at a concentration of 0.5%. The patties were kept under refrigeration at 4 ± 1°C during this time. The values of peroxide number, thiobarbituric acid, free fatty acid, and metmyoglobin pigment were decreased in the beef patties treated with the AMEUS. However, they increased continuously during the cryopreservation period, and there was a significant increase in water‐holding capacity (WHC) when the beef patties were treated with AMEUS. The results also showed that adding AMEUS to beef patties improved their qualitative characteristics.
