    Aflatoxin B1, total aflatoxin and ochratoxin A levels in wheat flour
    (Asian Journal Of Chemistry, 2007) Buyukunal, Serkan Kemal; Vural, Aydin
    In this study, 100 wheat flour specimens were analyzed with the ELISA technique regarding the amounts of total aflatoxin (AF), aflatoxin B-1 (AFB1) and ochratoxin A (OTA). The AF, AFB1 and OTA contaminations in the specimens were found to be 71, 0 and 87 %, respectively. The specimens with AF and AFB1 levels exceeding the maximum limits defined by the Turkish Food Codex and European Commission constituted 5 % of all, while the OTA contents did not exceed the allowed limits in any of the specimens that have been examined.

    Physico-chemical properties in honey from different regions of Turkey
    (Elsevier Sci Ltd, 2010) Kahraman, Tolga; Buyukunal, Serkan Kemal; Vural, Aydin; Altunatmaz, Sema Sandikci
    The present study was undertaken to determine the physico-chemical parameters of honey samples obtained from retailers in Marmara Region (Site 1) and East Anatolia (Site 2) of Turkey. The 70 samples were analysed for parameters including moisture, total acidity, diastase activity, hydroxymethylfurfural (HMF), invert sugar, sucrose, ash, commercial glucose and starch. 10 of 70(14.3%) honey samples were of unacceptable quality based on recommended criteria of moisture (3 of 70, 4.29%), diastase activity (3 of 70, 4.29%), HMF (2 of 70, 2.86%), invert sugar (4 of 70, 5.71%) and sucrose (2 of 70, 2.86%) by Turkish Food Codex and European Commission Regulation. The results of study indicated that 85.7% of honey samples were at good quality. It is important that the essential precautions should be taken to ensure standardisation and rationalisation of beekeeping techniques, manufacturing procedures and storing processes to improve honey quality.
