Beef semitendinosus steaks were used to evaluate the effects of sodium phosphate and potassium lactate on quality characteristics of enhanced beef steaks. Sodium phosphate decreased the amount of package purge and cook loss and gave the beef product a darker, redder appearance. Potassium lactate gave the product a darker, redder appearance, while increasing levels of lactate decreased total psychrotrophic (bacterial) plate counts, and decreased package purge and cook loss. Sodium phosphate and potassium lactate aid in extending shelf-life and improving quality attributes of enhanced beef steaks.
