The Effect of Storage Conditions (Temperature Degree and Storage Time) on the Most Important Properties of Locally Marketed Pastrami


Abstract in English

Pastrami, manufactured from beef and abdominal fat and of a ratio of 3 meat to 1 fat, was stored under refrigeration at (4±2 °C) and storage times (0, 15, 30, 60, 120, and 180 days). The effects of storage times on the most important chemical, microbiological and sensory properties of pastrami were investigated. The results of chemical analyzes showed that the studied pastrami conformed to the Syrian Standards in terms of the proportion of salt and fat content, and it nearly conformed to the standards in terms of humidity. The results also showed a slight decrease in the percentage of moisture, fat and protein, and an increase in each of the acidity, proportion of total volatile nitrogen, soluble nitrogen and peroxide value in pastrami with the progress of the storage period at the temperature degree (4±2 °C). The microbial tests showed that pastrami is free from some sickening organisms especially salmonella and E. coli. It also showed that the census of the aerobic bacteria, yeasts and fungi was within the limits of the Syrian standards. The results showed deterioration in the microbial properties of stored pastrami with the progress of time; pastrami became invalid from a microbial point of consumption after two months of storage as a result of the big number of aerobic bacteria, yeasts and fungi. The sensory tests showed deterioration in the organoleptic characteristics of storage with the progress of time, the deterioration was clear after two months of storage; pastrami became unacceptable in terms of taste, color, smell and texture.
