“…The oats used in the present experiment had been grown in a season with several weeks of dry and hot weather succeeded by rainfall and humid conditions from July until harvest in September, a typically favourable climate for Fusarium species. In Norwegian oats, Fusarium avenacium and Fusarium culmorum are the most frequently isolated species of this genus (Haave, 1985;Stenwig and Liven, 1988). Furthermore, this particular flora is liable to produce group B trichothecenes (Ichinoe and Kurata, 1983;Chelkowski et al, 1984), which was verified with chemical analysis in the present experiment.…”

1. The effect of feeding trichothecene-contaminated diets with graded concentrations of deoxynivalenol ranging from 120 to 4900 micrograms/kg to groups of laying hens was investigated. 2. Food intake, weight gain and egg production were not affected by mycotoxin administration. No significant differences were found between groups. 3. The overall results from the hatching tests did not reveal any significant differences in fertility, hatchability or perinatal mortality, which could be explained by the mycotoxin content in the diets. 4. Body weight at hatching and viability of the chicks were not affected by the mycotoxin concentrations in the diets. 5. The incidence of chick developmental anomalies was increased in the mycotoxin-administered groups compared to controls. Minor malformations were the dominating anomalies and included unwithdrawn yolk sac and delayed ossification. The most frequent major malformations were cloacal atresia and cardiac anomalies.

“…Mold growth is one of the causes of deterioration of flour during storage under sultry conditions because flour is hygroscopic in nature and absorbs moisture from its surroundings (Jay 1990). The colony‐forming units of molds per gram of sample varied from 1.2 × 10 4 to 99 × 10 7 of highly deteriorated Norwegian cereal grains (Stenwig and Liven 1988). Higher initial moisture content contributes more toward the spoilage of grain and flour (Sinha et al.…”

The effect of packaging materials on the physicochemical and rheological characteristics of iron-fortified wholemeal flour (WMF) during storage was determined. WMF was fortified with three fortificants, namely ferrous sulfate (30 ppm), ferrous sulfate + ethylenediamine tetraacetic acid (EDTA) (20 + 20 ppm) and elemental iron (60 ppm). Each flour was also fortified with 1.5 ppm folic acid. Moisture, flour acidity and peroxide value increased during storage, while protein and fat contents decreased. Highest conversion of Fe 2+ into Fe 3+ was observed in flour fortified with ferrous sulfate (2.72%), followed by that fortified with ferrous sulfate + EDTA (1.49%) and elemental iron (1.06%). Water absorption and dough viscosity of iron-fortified flours increased during storage. The flour containing ferrous sulfate was most acceptable regarding sensory characteristics, followed by samples containing ferrous sulfate + EDTA. Fortified flours were more stable during storage than unfortified. Addition of EDTA increased the stability of flours and fortificants. The fortified flours stored in polypropylene bags proved more stable than those stored in the tin boxes.

“…Многие годы совокупность культурально-морфологических признаков, введенных для описания таксона P. viridicatum Westling (9), служила основой для поиска этого микромицета в объектах окружающей среды (10,11) и изучения его токсинообразования (12,13). Однако позднее было предложено несколько подходов для выделения групп в пределах вида по фенотипическим, биосинтетическим и экологическим критериям (14)(15)(16).…”

В последние десятилетия достигнут значительный прогресс в изучении распространенности представителей рода Penicillium подрода Penicillium в объектах окружающей среды и способности этих грибов продуцировать широкий спектр токсичных метаболитов (T. Rundberget с соавт., 2004; J. O'Callaghan с соавт., 2013; M. Schmidt-Heydt с соавт., 2015). В ряде европейских стран для одного из видов -P. verrucosum Dierckx показана преимущественная распространенность на злаках и прямая связь с зараженностью зерна грибом и частотой обнаружения метаболитов с нефротоксическим действием (F.
