This study was made in descriptive form. Five different types of products sold on Istanbul markets were included in this investigation and their mycological quality control was performed. For this purpose un-supplemented Turkish delight (lokum), candies, jams and marmalades were collected and mycologically analyzed. Among the molds isolated and identified from the specimens the most commonly encountered mold was Aspergillus spp followed by Penicillium spp. In the third place Cladosporium was found. Among the Aspergillus spp. the heath threatening strains were A.glaucus, A.flavus, A.fumigatus, A.niger, A.ocrhaceus, A.restrictus, A.terreus, A.versicolor, A.candidus, all isolated and identified from the specimens.

As known the xerophilic and xerotolerant molds are able to grow easily in high concentrations of sugar. They are originally air or soil borne and are responsible of air and soil contamination. According to their growing environment there are able to produce some secondary toxic products. As results of the investigation, last products submitted to high heat showed lower mold contamination than the first and un-supplemented ones.
