Opis:
Introduction and objective. Mycotoxins are toxic metabolites produced by certain types of fungi, causing pathological changes in humans and animals. The aim of this study was to assess the degree of contamination of selected cereal grains, bran and cereal products intended for children, with mycotoxins using GCxGC-TOF-MS technique. The study involved mycotoxins belonging to the type A and B trichothecenes group, including T-2 toxin (T-2), HT-2 toxin (HT-2), scirpenol (SCI), 15-monoacetoxyscirpenol (15-MAS), diacetoxyscirpenol (DAS), triacetoxyscirpenol (TAS), fusarenon-X (FUS-X), nivalenol (NIV), deoxynivalenol (DON), 3-acetyl-DON (3-Ac-DON), 15-acetyl-DON (15-Ac-DON). The study also assessed the effect of conditions in which the samples were stored, including temperature (6 °C and 28 °C) and time (14 and 28 days), on fungal growth and mycotoxin production. Among all studied compounds, only DAS and HT-2 toxins were detected in tested samples, with the exception of products intended for children. Measured HT-2 mycotoxin content in tested samples was in the range 83.9 – 196.4 μg kg-1. Results and conclusions. Experiments with storage conditions showed a statistically significant increase in the HT-2 toxin level after 14 days of storage in all samples, irrespective of temperature. Prolonged storage (additional 14 days) did not cause significant changes in the HT-2 content. Further analyses showed a statistically significant effect of storage temperature on HT-2 toxin levels only in cereal products intended for children after both 14 and 28 days. Interestingly, lower temperature (6 °C) was more optimal then higher temperature (28 °C) for the HT-2 toxin production. No significant effect of storage temperature on HT-2 level was observed for cereal grains and bran.

Opis:
Introduction. The production volume of ecological food in Lubuskie Province tripled between 2007-2010. A majority of organic products on the market are cereal products, which constitute one of the sources of mycotoxins in both human and animal diets. The aim of the study was to compare the content of deoxynivalenol (DON) in cereals and in cereal grain derived from organic and conventional cultivations marketed in Lubuskie Province. Materials and methods. The material tested consisted of samples of cereal grain (wheat, rye, barley, oats) and cereals products (flour, groats, pasta). The concentration of deoxynivalenol (DON) in the items tested was determined by high performance liquid chromatography. Results. The study, which used product samples (cereals, grain, flour), targeted the presence of deoxynivalenol (DON). One case revealed that the highest permissible level (MRL) of the mycotoxins as determined by relevant regulations in force was exceeded. It also revealed a similar content of deoxynivalenol (DON) in grain and in cereals obtained from organic and conventional cultivations. Flour differentiated significantly as regards organic and conventional products, although unfavourably for the latter which were 80 per cent contaminated as compared to a 60% contamination prevalent in the organic ones. Deoxynivalenol (DON) was found in both types of products, yet it was the conventional products that showed the highest concentrations. Conclusion. Of the studied samples, those that were obtained from organic cultivations showed lower contamination levels as compared to conventional products. An increase in deoxynivalenol (DON) contamination occurs during the processing phase, the more processed the raw product, the higher the number of samples containing mycotoxin.
Wstęp. Produkcja żywności ekologicznej w województwie lubuskim zwiększyła się ponad trzykrotnie w latach 2007-2010. Zdecydowana większość produktów ekologicznych na rynku to produkty zbożowe, które są jednym z głównych źródeł mikotoksyn zarówno w diecie człowieka i zwierząt. Celem pracy było porównanie zawartości deoksyniwalenolu (DON) w zbożach i przetworach zbożowych pochodzących z upraw ekologicznych i konwencjonalnych, znajdujących się w obrocie handlowym na terenie województwa lubuskiego. Materiał i metody. Badaniami objęto próbki zbóż (pszenicy, żyta, jęczmienia, owsa) i przetworów zbożowych (mąki, kasze, makarony) pod kątem obecności w nich deoksyniwalenolu (DON). Stężenie deoksyniwalenolu (DON) w badanych produktach określano metodą wysokosprawnej chromatografii cieczowej (HPLC). Wyniki. W jednym przypadku stwierdzono przekroczenia najwyższego dopuszczalnego poziomu (NDP) badanej mikotoksyny, określonego w obowiązującym rozporządzeniu. Badania wykazały podobną zawartość deoksyniwalenolu (DON) w zbożu i przetworach zbożowych pochodzących z produkcji zarówno ekologicznej, jak i konwencjonalnej. W przypadku mąki zaistniała istotna różnica pomiędzy produktami ekologicznymi i konwencjonalnymi na niekorzyść tych drugich, gdzie skażonych było 60% próbek z produkcji ekologicznej i 80% konwencjonalnej. Deoksyniwalenol (DON) odnotowano w obu rodzajach produktów, przy czym największe jego stężenie wystąpiło w produktach konwencjonalnych. Wnioski. W badanych próbkach, produkty z upraw ekologicznych wykazują mniejsze skażenie deoksyniwalenolem (DON) niż produkty z upraw konwencjonalnych. Odnotowano wzrost skażenia deoksyniwalenolem (DON) badanych produktów w fazie przetwórstwa (im bardziej przetworzony surowiec, tym więcej odnotowano próbek z zawartością mikotoksyny).

Opis:
Background. Cereal grains and their products are among the basic components of the diet all over the world. Their consumption varies depending on the dietary habits in each country. Apart from ingredients valuable from a health point of view, these products can also be a source of contaminants. The European Food Safety Authority (EFSA) included these foodstuffs in the group of main contributors to the dietary exposure to nickel by different groups of the population. Objective. The aim of the studies was to determine the nickel content in cereal grains and selected cereal products commercially available in Poland and to assess the exposure of consumers to nickel intake with these foodstuffs. Material and methods. A total of 56 samples of cereal grain and cereal products from trade were tested. Nickel content was determined after microwave mineralization of the samples by atomic absorption spectrometry with a graphite furnace atomization (GFAAS). The estimated exposure for the different groups of the population was assessed and compared with the Tolerable Daily Intake (TDI) value established by the European Food Safety Authority based on an updated risk assessment at 13 μg/kg body weight (b.w.) per day. Results. The mean (MB) and 95th percentile (MB) nickel content in investigated samples of cereal grains and their products were 0.66 mg/kg and 1.93 mg/kg. The mean content of Ni in the analyzed samples of grains was 1.16 mg/kg. Obtained results in this group of products ranged from 0.10 mg/kg for rye to 4.80 mg/kg for millet. In the group of grain products, the mean (MB) concentration of nickel was 0.61 mg/kg (95th percentile (MB) 1.84 mg/kg). The highest nickel level was determined in the samples of bran, groats, and flakes compared to other grain-based products. The highest content of Ni in the group of cereal products was found in the samples of roasted buckwheat 1.81 mg/kg and oat flakes 2.53 mg/kg. Significantly lower nickel content was observed in barley groats as well as for pasta and flour. The estimated average exposure of adults and children to nickel intake with grains and grain-based products ranged from 1.1% to 13.4% of TDI and it does not pose a health risk for consumers. Conclusions. Based on the obtained results, it was found that the nickel content in the tested samples of cereals and their products does not pose a health risk, even though the contamination of individual samples was significant

Opis:
This review article is based on scientific and popular science publications as well as articles from branch magazines that refer to the production of alcohol in Poland based on traditional grain raw materials. New trends in the production of broadly understood alcoholic beverages point to a return to traditional raw materials and production methods, preferably carried out in small, traditional distillery – crafted beers, local wines or spirits. Consumers desire a return to tradition, however, it is equally important to maintain the right quality and efficiency of production. The future of alcoholic beverages based on malted and unmalted cereals in Poland is associated with the search for specific varieties of cereals, their mixtures as well as fermentation and distillation processes that will allow the production of ‘craft spirits’.
