Abstract
The impact of multiple antimicrobial interventions on ground beef processing, lipid, textural, instrumental color and sensory characteristics were evaluated. Beef trimmings were treated with 0.5% cetylpyridinium chloride followed by 10% trisodium phosphate (CT), 200-ppm chlorine dioxide followed by 0.5% cetylpyridinium chloride (CLC), 200-ppm chlorine dioxide followed by 10% trisodium phosphate (CLT), or 2% lactic acid followed by 0.5% cetylpyridinium chloride (LC) and compared to an untreated control (C). Sensory panelists found LC and CT treatments similar ( P>0.05) in grinding ability to C. By day 2 of display, CT, CLT and LC patties were redder ( a ∗; P<0.05) than C. Sensory panelists found CT patties redder ( P<0.05) than C by day 2 of display. Sensory panelists found CT and CLT juicier than C. Therefore, the use of these multiple antimicrobial intervention agents on beef trimmings may improve sensory characteristics and shelf-life of ground beef patties.
