  ABSTRACT: Meat color is an intrinsic property that plays a major role in consumer’s perception. Lipid oxidation by-products as well as free iron can adversely affect meat color. This study was to compare the effect of Type I (radical quenching) antioxidants eugenol and rosmarinic acid (RA) to that of Type II (metal chelating) antioxidants milk mineral (MM), phytate, and sodium tri-polyphosphate (STPP) in raw ground chicken patties packed with a single layer of polyvinylchloride (PVC) overwrap. Packaged patties were stored at 4℃ and analyzed on 0, 1, 4, 7, and 10 days for pH, surface color, extent of lipid oxidation, oxymyoglobin content, and microbial load. Color stability was measured using Hunter MiniScan calorimeter (L*, a*, b* values). An effect was observed in L* values (P
