Effect of vacuum-packing method on the shelf-life of Capoeta umbla sausages

The effect of vacuum packing on the shelf-life of sausages produced from Capoeta umbla were investigated during storage periods. For this purpose, microbial, chemical and sensory changes were analyzed throughout the storage time. The microbial flora of the sausages comprised mainly mesophilic bacteria, psychrotrophic bacteria, lactic acid bacteria, yeast and molds. Escherichia coli, Staphylococcus aureus and coliforms were not detected in the sausage samples. Total volatile basic nitrogen (TVB-N) and thiobarbituric acid (TBA) increased gradually with storage time while the concentration of moisture was not affected during the storage period. Application of vacuum-packing at 4±1°C extended the shelf-life of sausage samples by approximately 30 days

Effect of brine and dry salting methods on the physicochemical and microbial quality of chub (Squalius cephalus Linnaeus, 1758)

The present study, looks at the physicochemical and microbiological quality changes that occur due to different salting techniques (20% salt concentration) of chub (Squalius cephalus) and when stored in 4 ± 0.5 °C. Samples of fish from each group was taken on the 15, 30, 45, 60, 90 and 120th day and was analyzed for nutritional component (crude protein, lipid, moisture, crude ash), pH value, salt content and the microbial flora (total mesophilic aerobic bacteria count, total coliform, total psychrophilic aerobic bacteria count, yeast and mould). It was determined that crude protein, lipid, crude ash and salt amounts in the group where dry salting method was applied were higher than the group where brine salting occurred, in addition protein and lipid values decreased as storage period was longer (P < 0.05). It was determined that there is an increase in total aerobic mesophilic, psycrophile bacteria and enumeration of yeast and mould as storage period increased, while coliform bacteria decreased (P < 0.05).This work was supported by Munzur University Scientific Projects Coordination Department (Project Number: YLTUB012-03)
