    Gluten status in gluten-free pastry and bakery products produced in Istanbul, Turkey
    (Sidas Medya A.S., 2023) Kaya, Yeliz Miral; Çoban Dinçsoy, Ayşen
    Gluten is a complex protein that forms the basis of bakery products, including pastry products, with its elasticity. Gluten proteins are constituted by gliadin and glutenin. Gliadin, which is in the water-insoluble protein group, is very difficult to digest. Many immune disorders influence a growing number of people in relation to the consumption of wheat flour-based foods. The aim of this study is to determine the status of gluten-free products with the legal limits of the gluten-free products sold in pastry shops and bakeries in Istanbul, Turkey. Ninety samples in total including gluten-free bread, cakes, cookies, snacks, and cereals were collected from various regions of Istanbul in November 2020. The samples obtained were examined by ELISA (Enzyme-Linked Immunosorbent Assay) for the presence of gluten. As a result, the presence of gluten was found to be lower than 5 ppm in 61 samples (67.7%), between 5-20 ppm in 8 samples (8.8%), and 20 ppm and above in 21 samples (23%). Within the scope of Turkish Food Codex Regulation on Food Labeling and Consumer Information Number 29960, some foods were inappropriate products which offered to consumption as gluten-free in patisseries and bakeries. It could be thought that risks might be reduced to the maximum extent with hygiene and sanitation training in food businesses, analysis in terms of gluten in raw materials and final products, control of contamination from raw materials, personnel and environment during the production phase, and gluten analysis at critical points.
