Mineral and Trace Metal Levels of Akcakatik Cheese Collected From Mediterranean Region-Turkey
(Asian Journal of Chemistry, 2013) Kirdar, S. S.; Ocak, E.; Kose, S.
In this study, 15 randomly selected samples of Akcakatik, cheese were purchased from different markets in Mediterranean region of Turkey. Mineral, trace and heavy metals including calcium, potassium, magnesium, copper, manganese, iron and zinc were analyzed I, using atomic absorption spectrometry. The ash content was in the range 4.89-8.53 %. The mean concentration of 49.62, 417.74 and 2842.24 mg/kg was measured for Mg, K and Ca, respectively. The concentration of the tested metals was in the range Zn > Fe > Mn > Cu. I The mean concentration of 3.36, 6.15, 12.62 and 13.92 mg/kg was measured for Cu, Mn, Fe and Zn, respectively. In our samples, tested levels were higher than reported in previous studies, except the elements Fe and Ca.
Seasonal Changes in Mineral and Trace Elements of Canak Cheese
(Asian Journal of Chemistry, 2013) Kirdar, S. S.; Ocak, E.; Kose, S.; Ozer, E.
Seasonal changes of the ash content and mineral concentrations in Canak cheese were studied. Mineral, trace and heavy metals including calcium, potassium, magnesium, copper, manganese, iron and zinc were analyzed using atomic absorption spectrometry. At the end of the study, the ash content averaged 3.85 +/- 0.26 % in the winter samples and 3.00 +/- 0.14 % in the summer ones. The mean concentration of 63,92, 296,74 and 1571,60 mg/kg (in winter) and 56,69, 225,61 and 1221.46 mg/kg (in summer) were measured for Mg, K and Ca, respectively. The concentration of the tested metals was in the range Zn > Fe > Cu > Mn over two seasons. Differences in mineral contents in the cheese making season was statistically significant (p < 0.01) significant seasonal variation was found for Ca, K, Mn and Fe (p < 0.01).
