Influence of Different Fruit Additives on Some Properties of Stirred Yoghurt During Storage
(2004) Küçüköner, E.; Tarakçi, Z.
In this study, stirred type yoghurt with rosehip, cornelian andmorello cherry (jam), grape (molasses), date (pulp) added and control set type yoghurt were produced and stored up to 10 days at 4 ± 1°C. Physico-chemical, microbiological properties and sensory quality of yoghurt samples were evaluated at day 1, 6 and 10 of storage. According to analysis during storage total solids were found to be 14.58-20.51%, fat 2.95-3.10%, protein 3.61-4.34%, ash content 0.82-1.08%, titratable acidity (TA) 1.27-1.62, and pH 3.93-4.29 were found during storage. Syneresis and TA increased over the storage period. Total mesophilic bacteria count were significantly different among yoghurt samples (p < 0.05). Moreover, mold and yeast count showed significant increase during storage period. Sensory evaluation showed that there were no statistical differences among the yoghurt samples.
Survey of Trace Metals in Turkish Kes Cheese
(Freund Publishing House Ltd, 2008) Kiliçel, F.; Tarakçi, Z.; Sancak, H.; Durmaz, H.
Kes cheese, a traditional Turkish dairy product, is commonly made around Ordu, Giresun and other cities in Blacksea region of Turkey. The different heavy metals were determined in commercial Turkish Kes cheese by Flame Atomic Absorption Spectrometer (FAAS). The concentration ranges in the samples were determined to be 4.30-37.30, 7.10-22.30, 5.90-47.80, 0.23-1.92, 0.04-0.75, 0.03-0.26, 0.04-0.44 and 2.31-7.25 μg/g, dry weight for zinc, iron, cupper, manganese, lead, cadmium, cobalt and chromium, respectively. The results were compared with those reported in recent years. The metal levels were compared with previous data for different cheeses. Fe, Cu and Cr mean concentrations were found to be higher. The overall mean concentrations of Zn, Mn, Pb, Cd and Co levels were in agreement with the values of other cheeses.
