Presence of Enniatins and Beauvericin in Romanian Wheat Samples: From Raw Material to Products for Direct Human Consumption

2017

In this study, a total of 244 wheat and wheat-based products collected from Romania were analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS) in order to evaluate the presence of four enniatins (ENs; i.e., ENA, ENA1, ENB, and ENB1) and beauvericin (BEA). For the wheat samples, the influence of agricultural practices was assessed, whereas the results for the wheat-based products were used to calculate the estimated daily intake of emerging mycotoxins through wheat consumption for the Romanian population. ENB presented the highest incidence (41% in wheat and 32% in wheat-based products), with its maximum levels of 815 μg kg−1 and 170 μg kg−1 in wheat and wheat-based products,…

Effects of Bread Making and Wheat Germ Addition on the Natural Deoxynivalenol Content in Bread

2014

Deoxynivalenol (DON, vomitoxin) is a type-B trichothecene mycotoxin produced by several field fungi such as Fusarium graminearum and Fusarium culmorum and known to have various toxic effects. This study investigated the effect of the bread making process on the stability of DON in common bread and wheat germ-enriched bread using naturally contaminated ingredients at the level of 560 µg/kg. The concentration of DON and its evolution during bread making were determined by immunoaffinity column cleanup followed by liquid chromatography with diode array detection (HPLC-DAD). During the bread making process, DON was reduced by 2.1% after fermentation and dropped by 7.1% after baking, reaching a …

Hedging effectiveness of European wheat futures markets

2014

The instability of commodity prices and the hypothesis that speculative behaviour was one of its causes has brought renewed interest in futures markets. In this paper, the hedging effectiveness of European and US wheat futures markets were studied to test whether they were affected by the high price instability after 2007. Implicitly, this is a test of whether the increasing presence of speculation in futures markets have made them divorced from the physical markets. A multivariate GARCH model was applied to compute optimal hedging ratios. No important evidence was found of a change in the effectiveness of hedging after 2007.

Effect of The Gluten-Free Diet on Quality of Life, Gastrointestinal Symptoms and Immune System in Patients with Fibromyalgia and Non-Celiac Wheat Sen…

2021

Fibromyalgia (FM) is a clinical syndrome characterized by chronic pain. FM patients complain hyperalgesia and allodynia and they are frequently affected by Non Celiac Wheat Sensitivity (NCWS), a condition where gastrointestinal and extraintestinal symptoms are triggered by gluten and/or wheat ingestion. The gluten-free diet (GFD) impact was evaluated on fibromyalgia-related and gastrointestinal symptoms, health-related quality of life and immune response of patients with both FM and NCWS in order to detect a possible pathogenetic role of wheat/gluten in the triggering of the inflammatory process. Peripheral blood from 8 FM patients, 10 FM and NCWS patients (FM+NCWS patients), 13 NCWS patien…

Influence of Bacterial Secondary Symbionts in Sitobion avenae on Its Survival Fitness against Entomopathogenic Fungi, Beauveria bassiana and Metarhiz…

2022

The research was focused on the ability of wheat aphids Sitobion avenae, harboring bacterial secondary symbionts (BSS) Hamiltonella defensa or Regiella insecticola, to withstand exposure to fungal isolates of Beauveria bassiana and Metarhizium brunneum. In comparison to aphids lacking bacterial secondary symbionts, BSS considerably increased the lifespan of wheat aphids exposed to B. bassiana strains (Bb1022, EABb04/01-Tip) and M. brunneum strains (ART 2825 and BIPESCO 5) and also reduced the aphids’ mortality. The wheat aphid clones lacking bacterial secondary symbionts were shown to be particularly vulnerable to M. brunneum strain BIPESCO 5. As opposed to wheat aphids carrying bacterial s…

Regarding the first question, however, we believe that there is a clear answer in the article itself. We stated, in the Methods section, that “the biopsy specimens were assessed in Palermo by 2 pathologists (G.G. and/or A.M.F.)”; the eosinophil count, which seems to be one of the most important findings of the study, “was further assessed by an experienced gastrointestinal pathologist (V.V.) in Brescia.” We also added that “all reviewers were blinded to the diet allocation and final diagnosis of each patient.” Consequently, the k value provided in the Results section referred to the agreement between the evaluation performed in Palermo and the evaluation performed in Brescia. No further det…

An integrated technological approach to the selection of lactic acid bacteria of flour origin for sourdough production

2013

article i nfo Several lactic acid bacteria (LAB) were evaluated in situ for their potential in sourdough fermentation. The strains belonged to Lactobacillus plantarum, Lactobacillus sakei, Lactobacillus sanfranciscensis, Leuconostoc citreum, Leuconostoc mesenteroides, Leuconostoc pseudomesenteroides and Weissella cibaria. LAB were used, in individual inocula, to carry out the fermentation of γ-ray treated (sterile) flour and untreated commercial flour, in order to evaluate their performances both in the absence and presence of the native microbiota of flour. The pH and total titratable acidity (TTA) showed a strong and fast acidification of the experimental sourdough determined by W. cibari…

Forecasting Wheat Yield Using Remote Sensing: The ARYA Forecasting System

2021

In this study we present a model to forecast wheat yield based on the evolution of the Difference Vegetation Index (DVI) and the Growing Degree Days (GDD), presented in Franch et al. (2015), but adapted to Franch et al. (2019) model. Additionally, we explore how the Land Surface Temperature (LST) can be included into the model and if this parameter adds any value to the model when combined with the optical information. This study is applied to MODIS data at 1km resolution to monitor the national and state level yield of winter wheat in the United States and Ukraine from 2001 to 2019.
