OpenAlex İngilizce

In this study, quality properties and shelf life for gibel carp ( Carassius gibelio , Bloch 1782) marinades during stored at 4±1 °C in different sauces was investigated. The marinating process was carried out in 2.5% vinegar, 10% salt and water for 72h at 4±1 °C. After the marination process, fish were removed from the solutions, transferred in to glass jar contain with different sauces (Group A: sunflower oil and tomato paste, Group B: sunflower oil with garlic, red pepper, thyme, basil and mint and the control group: sun flower oil). Sensory, chemical, colour and microbiological analyses were performed during the storage. According the chemical analysis results TVB-N and TBA values of all groups were increased during the storage, but during the stored period did not exceed acceptible limit values. The highest TVB-N and TBA values were group A. (P<0,05). At the end of 135 days of storage, sensory analysis results pointed out that the marinades of group B did not exceed acceptible limit values (P<0,05). The overall microbial load of the fresh samples decreased through out the storage period (P<0,05). By sensory data, shelf life of sauced gibel carp marinades were 120 days (control), 105 days (group A) and 135 days (group B).
