EFFECTS OF PACKAGING METHODS ON THE MICROBIAL FLORA OF LIVERS AND KIDNEYS FROM BEEF OR PORK.

Type of article: Article

Summary

AEROBIC PLATE COUNTS OF VACUUM-PACKAGED BEEF LIVERS, BEEF KIDNEYS AND PORK LIVERS DURING REFRIGERATED STORAGE WERE NEARLY ALWAYS, PARTICULARLY AFTER 14 DAYS AT 275K (2 DEG C), MUCH LOWER THAN THOSE OF COMPARABLE SAMPLES PACKAGED IN PVC FILM. THE PH OF VACUUM-PACKAGED LIVERS AND KIDNEYS DECREASED DURING REFRIGERATED STORAGE; THE SAME WAS FOR PRODUCTS STORED IN PVC FILM EXCEPT THAT THE PH OF KIDNEYS INCREASED. IN REFRIGERATED VACUUM-PACKAGED LIVERS AND KIDNEYS, LACTIC ACID BACTERIA (HOMO-AND HETEROFERMENTATIVE LACTOBACILLI, STREPTOCOCCI, LEUCONOSTOC SP.) BECAME MORE PREDOMINANT, WHERAS IN PRODUCTS PACKAGED IN PVC FILM, GRAM-NEGATIVE BACTERIA FREQUENTLY BECAME MORE DOMINANT.
