    Presence of enterobacter sakazakii in milk powder, whey powder and white cheese produced in Konya
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2010) Gokmen, Mukadderat; Tekinsen, Kemal Kaan; Gurbuz, Umit
    Enterobacter sakazakii has been caused foodborne illnesses through consumption of a variety of foods such as milk powder, cheese, sausage, particularly infant foods. In this study, the presence of E. sakazakii were investigated in 60 milk powder, 50 whey powder and 50 white cheese. ISO/TS 22964 (IDF/RM 210) method was used for detection E. sakazakii. E. sakazakii was identified from milk powder 5% (3/60), white cheese 4% (2/50). E. sakazakii was not detected in whey powder. According to Commission Regulation (EC) and Turkish Food Codex Microbiological Criteria Communique E. sakazakii must not present in infant formulae, formulae for special medical purposes and follow-on formulae. Also in many countries, E. sakazakii infections associated with most of the milk-based products that have been reported. In conclusion, the results indicate that milk powder and white cheese produced some dairy plants in Konya presents a risk in terms of human health and the necessary precaution will have to be taken to carry out effective sanitary practices in the plants.

    Use of chitosan in Turkish sausage (sucuk) production and effects on quality
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2011) Gokmen, Mukadderat; Gurbuz, Umit
    This study aims to investigate the effect of chitosan, natural polysaccharide, use in different proportions (0.05%, 0.1%, 0.5% and 1%) on the quality of Turkish sausage production. In the study, as a control group, the first group was added only 0.05% nitrate. Microbiological analysis (total aerobic mesophilic bacteria, Enterobacteriaceae, coliform and Escherichia coli, sulphite-reducing clostridia, mold-yeast count) was done in the four different stages of experimental sausage production, (meat [DN1], after mixing [DN2], after filling [DN3], after ripening [DN4]) and on the 1, 7, 15, 30 and 60 days of the storage. Sensory qualities of experimental sausage samples (flavor, color, appearance and texture) were evaluated in the DN4. It was then determined that a little amount of chitosan addition (0.05%, 0.1% and 0.5%) into the production of Turkish sausage affected the microbiological and sensory quality positively. However, addition of much larger amounts (such as 1%) affected the sensory quality in a negative way. Moreover, it was determined that higher amounts of chitosan applications (0.5% and 1%) created technological problems.
