The aims of this study were to evaluate and compare proximate composition, antihypertensive activity and antioxidative capacity of the semimeinbranosus muscle from pork and beef and to study how these characteristics were affected by household preparation and subsequent digestion. The proximate composition was similar between pork and beef. Both pork and beef contained protein with the essential amino acids. Cooking in a heated pan did not affect the retention of lipid or sum of amino acids, but reduced the amount of the free amino add taurine. The antihypertensive effect did not differ significantly between pork and beef, whereas the antioxidative capacity did. Cooking affected the antioxidative capacity negatively. The results from this study show that pork and beef are equally good sources of protein and bioactive properties, and whereas the nutritional composition is not affected, bioactive properties may be reduced after household preparations.
