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, micr
obiological 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.
