    5-hydroxymethylfurfural content in selected gluten- and gluten-free cereal food products
    (Lodz University of Technology Press, 2017) Mańkowska, Dorota; Majak, Iwona; Bartos, Adrian; Słowianek, Marta; Łącka, Agata; Leszczyńska, Joanna
    5-Hydroxymethylfurfural (HMF) was determined with HPLC method in forty one food samples, including gluten-free, breakfast cereals and bakery products. The highest concentration of HMF was found in wheat bread with cranberries (210 mg kg-1) and in breakfast cereals – honey wheat loops (85.099 mg kg-1). In contrast, wholegrain oatmeal and gluten-free sponge cakes had the lowest HMF level of all tested samples, below the detection limit and 0.485 mg kg-1, respectively. In most cases, lack of gluten coincided with the lowest HMF content readings (average 8.488 mg kg-1). The impact of the type of sugar, especially glucose, on the HMF concentration in food is apparent. Sweetened breakfast cereals, with the average content of HMF at 25.55 mg kg-1, took lead over dietary products (8.488 mg kg-1) and bakery products (18.395 mg kg-1), with the exception for wheat bread with cranberries. These cereals contained glucose or glucose-fructose syrup.

    Methods of allergen detection based on DNA analysis
    (Wydawnictwo Politechniki Łódzkiej, 2011) Słowianek, Marta; Majak, Iwona
    Many allergens, such as hazelnut, peanut, charlock, celery, sesame, lupine, walnut, almond, macadamia nut, hickory, pistachio, wheat gliadins, may be present in food products, however, undeclared or as unintentional additives. Due to the growing number of allergic reactions, it is crucial to have fast, reliable methods of allergen detection in processed food products. This review summarizes the recent methods of allergen detection in food products based on PCR reactions, namely PCR-ELISA, Real-time PCR, PCR-PNA-HPLC, Duplex PCR and Multiplex Real-time PCR, describing their principles, applications, detection limits, drawbacks and advantages.
