A Comparison of Growth of Individual Meat Bacteria on the Lean and Fatty Tissue of Beef, Pork and Lamb

摘要

ABSTRACTGrowth ofHafnia alvei, Serratia liquefaciens, Lactobacillus plantarum, Lactobacillus curvatusandLeuconostoc mesenteroideson inoculated lean and fat tissue of beef, pork and lamb was investigated. Increases inH. alvei, S. liquefaciensandL. plantarumcounts on refrigerated beef and pork fat usually were greater (P<0.05) than on comparable lean samples. On dark‐firm‐dry (DFD) beef, these differences in counts between lean and fat samples were smaller or disappeared. Increases inL. mesenteroidesandL. curvatuscounts on fat were either smaller than or did not differ from those on lean samples. Sour, buttermilk‐like off‐odors were the most common defect on stored
