The sea buckthorn has proven antioxidant properties. The aim of the study was to determine the effect of the addition of dry Hippophae rhamnoides extract on the functional and oxidative stability of traditional Kazakh molded smoked ham. Sea buckthorn extraction parameters were optimized by factorial experimental design and polynomial regression modelling. The optimal dosages of acid value, peroxide value, TBARS, and sensory-assessed cross-sectional surface were determined. The instrumental color, pH, texture profile, hydrolytic and oxidative changes in lipid and protein fractions, total phenolic content, antioxidant activity, and microbiological status of ham with 3% extract were evaluated over 30 d at 0–4 °C. An increase in total phenols (19.8%), radical scavenging activity against DPPH (33.6%), and FRAP (12.8%) was found. The addition of 3.0% sea buckthorn extract had a minor effect on the oxidative processes. Dry sea buckthorn extract can be successfully added to the production of traditional Kazakh molded smoked ham from horse and camel meat to stabilize the oxidative stability of the product.
