| dc.description.abstract | The objective of this study was to extend the shelf life of ground beef in chilled conditions. Samples were treated with 2% salt, 2% salt + 500-ppm ascorbic acid, or 2% salt + 100-ppm sodium nitrite. The control sample did not contain any additives. Protein, nitrite, moisture contents, pH, thiobarbituric acid (TBA) value, color attributes and microbial counts of samples were determined. Samples were vacuum packaged and stored in refrigeration, and chemical and microbial analyses were performed throughout storage. The pH of samples decreased during storage, and the sample having 2% salt and 500-ppm ascorbic acid had the greatest pH decline. TBA values generally increased (P < 0.05) with storage time. Samples having 2% salt + 500-ppm ascorbic acid had the lowest TBA value. On a given storage day, samples having 2% salt + 100-ppm sodium nitrite had lower microbial microbial count than other samples, indicating the antibacterial effect of nitrite. A significant storage time × treatment interaction (P < 0.05) existed for almost all quality parameters studied. PRACTICAL APPLICATIONS Ground beef has commercial importance for the meat industry in Turkey. Meat processors have difficulties in marketing ground beef because of its relatively low shelf life. By adding ascorbic acid or salt, it is possible to extend shelf life and preserve its color, and to limit lipid oxidation, which will collectively help to increase market share of ground beef. © 2009, Wiley Periodicals, Inc. | |
