The Effect Of Sodium And Potassium Nitrate On The Quality Of Turkish Pastrami (Pastırma) During Production, Yusuf Doğruer, Ahmet Güner, Ümi̇t Gürbüz, Gürkan Uçar

Turkish Journal of Veterinary & Animal Sciences

Different ratios of sodium and potassium nitrate were added to salt (control, 1, 2 and 3%) during the salting process and its effect on the chemical and microbiological quality was investigated in different stages of Turkish pastrami (pastırma) production (before and after salting, and before and after cumin paste application). According to the chemical analysis results, the moisture and salt ratio, pH and a_w values were not significantly different between the groups (P > 0.05) but the nitrate and nitrite values were significantly different according to the nitrate ratio (P < 0.05). Before the salting of samples, Staphyococcus/Micrococcus numbers were significantly different between the groups (P < 0.05). In the other stages of production, no differences were found between the groups (P > 0.05). Except for the stages before salting, no coliform-group bacteria growth …

Turkish Journal of Veterinary & Animal Sciences

In this research the fatty acid composition of different tissues of mature trout caught from Yeşildere creek in the Fırat region were investigated. In the adipose, gonad, liver and muscle tissues, the differences among the percentages of monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (n-3, n-6 PUFA) and the eicosapentaenoic acid (EPA)/decosahexaenoic acid (DHA) ratio were statistically significant (P < 0.01). However, the differences in the saturated fatty acids (SFA) of tissues were not distinctive. The most important fatty acids were palmitic (16:0), stearic (18:0) and miristic (14:0) in SFA and 18:1 n-9 and 16:1 n-7 in MUFA. The ratio of n3/n6, known as characteristic agents of marine fish, was as high as in marine fish but the differences among the tissues were not significant.

Turkish Journal of Veterinary & Animal Sciences

The gonad histology and spawning pattern of the white grouper (Epinephelus aeneus) were determined from fish sampled from commercial catches. Histological, microscopic and macroscopic techniques were used to examine the ovaries of E. aeneus. A six stage maturity scale based on morphology was proposed to classify ovarian development. The results showed that the white grouper has an asynchronous mode of ovarian development, and the histological study of oocyte development in the white grouper indicated that two types of inclusion, first lipid and then protein, are formed during vitellogenesis. Towards maturation, protein granules and lipid droplets increased in size and number …

Turkish Journal of Veterinary & Animal Sciences

The stomach contents of 122 common carp (Cyprinus carpio L., 1758) individuals collected from lakes Tatlı and Gıcı between January 2000 and December 2000 were investigated. The Geometric Index of Importance (GII) was used to determine food preferences among individuals and to assess whether these preferences were age based. It was concluded that the diet preferences of the common carp were not dependent on age and comprise a wide variety of food items present in their natural habitat. The results are presented in tables and figures.

Turkish Journal of Veterinary & Animal Sciences

Diabetes mellitus was induced in Wistar-Albino type male rats with a single dose of streptozotocin (60 mg/kg intraperitoneally). The kinetic properties of pyruvate kinase were investigated in normal and diabetic rat liver tissue. In normal rat liver tissue, the incubation period of pyruvate kinase was 15 min and the optimum pH was 8. In diabetic rat liver tissue, the incubation period of pyruvate kinase was 10 min and the optimum pH was 7. Activation was found in normal and diabetic rat liver tissues with magnesium chloride and potassium chloride. Phospho(enol)pyruvate is an enzyme substrate; in the absence of the fructose-1,6-diphosphate …
