Abstract

In order to compare effects of VACUUM and simple PACKAGING on chemical and microbial parameters related to SHELF LIFE of chilled beef in this study, 35 Kgs de boned beef (shoulder) were randomly divided into 35 VACUUM packs and 35 simple packs (without VACUUM) so that the weight of each pack was 0.5 kg. In five replications and in each of them, every simple pack was examined by chemical (pH, peroxide value, TVN) and microbial tests (total count, coliform and psychrotrophe counts) after first day and first, 2nd, 3rd, 4th, 5th and 6th weeks of keeping at 2-46.The results were as follow from 4th to 6th week, pH of MEAT in VACUUM pack was lower than it in simple pack (P<0.05) from 2nd to 6th week, peroxide value and TVN of MEAT in VACUUM pack were lower than those in simple pack (P<0.05).At 2nd and 3rd weeks, total count in VACUUM pack was lower than it in simple pack (P<0.05). At 3rd and 4th week, coliform count in VACUUM pack was lower than it in simple pack (P<0.05). At first, 2nd, 5th and 6th weeks, psychrotrophe count in VACUUM packs was lower than it in simple pack (P<0.05).Overall, it was concluded that decrease in amounts of assessed parameters in VACUUM packs in relation to simple packs during keeping of beef at 2-46 for 6 weeks, has resulted in increasing the SHELF LIFE of VACUUM packed beef to 2-4 weeks more than it in simple packed beef.
