The present study was conducted to evaluate the effect of ultrasound and aqueous extract of oil palm fronds (OPF) powder on the quality attributes of ultrasonic-assisted marinated (UAM) goat meat. The OPF extraction was carried out at powder to solvent (filtered water) of 1:7.5 w/v ratio and ultrasound application (37-kHz frequency, 150 W power at 40°C temperature for 20 min). The goat meat marination was done by applying ultrasonic treatment (280 W power, 37 kHz frequency, 30 min below 10°C) and adding 1.0% OPF extract viz., Control (marinade without extract and no ultrasonication), T1 (marinade with 1.0% OPF extract, no ultrasonication), T2 (marinade with ultrasonication), and T3 (marinade with 1.0% OPF extract and ultrasonication). The samples were analysed on day 0 (immediately after 30 min) and were stored under refrigeration and evaluated for various quality parameters on 1 and 3 days. The ultrasonic and extract incorporation resulted in a significant (p<0.05) increase in marinade pick-up and a significant (p<0.05) decrease in shear force value. Ultrasonic application (T2 and T3 samples) resulted in a higher cooking loss as compared to control and T1 on day 0 but the cooking loss of all treated samples was comparable on day 3 of refrigerated storage. The ultrasound and extract incorporation improved the appearance, flavour, and tenderness of the goat meat. Thus, the ultrasonic application for 30 min with 1.0% OPF extract in the marinade improved the quality attributes of marinated goat meat.
• Aqueous extract of oil palm fronds exhibited potent antioxidant potential.
• Ultrasonic application improved marinade pick-up, appearance, flavour, and tenderness of the goat meat.
• A 30 minutes ultrasonic application and 1% aqueous extract of oil palm fronds improved goat meat quality attributes.
