Reactivity to allergenic food contaminants: A study on products on the market

Background: The frequency and severity of reactions in food-allergic consumers exposed to unintentional food allergen contamination during production is unknown. To warn allergic consumers, it has been suggested for pre-packaged foods to be precautionary labelled when the food allergen contamination may exceed the amount to which 1%-5% of the population could react (ED01-ED05). ED01 for […]

Clinically and industrially relevant incurred reference materials to improve analysis of food allergens, milk, egg, almond, hazelnut and walnut

Measurement of food allergen protein concentrations against thresholds can improve allergen risk management and precautionary allergen labelling. Such measurement suffers well known problems which could be ameliorated by well characterised reference materials (RMs) providing meaningful information for risk assessors. We investigated the preparation and characterisation of the first consensus informed industrially and clinically relevant multi-allergen […]

Performance of two egg parasitoids of brown marmorated stink bug before and after cold storage

Introduction: The genus Trissolcus includes a number of egg parasitoids that are known to contribute to the control of Halyomorpha halys. The number of progenies, particularly females, is important for the efficient mass rearing of species used in augmentative biological control programs. Cold storage is an important technique for extending the shelf life of natural […]

Dietary Fibers of Tree Nuts Differ in Composition and Distinctly Impact the Fecal Microbiota and Metabolic Outcomes In Vitro

This study aimed to evaluate and compare the effects of dietary fibers (DFs) of commercially important tree nuts (almond, cashew, hazelnut, pistachio, and walnut) on gut microbiota in vitro. Microbial compositions and short-chain fatty acids were determined using 16S rRNA sequencing and gas chromatography (GC), respectively. Neutral and acidic monosaccharides were analyzed using GC/MS and […]

Evaluation of hazelnut production in Türkiye in environment, energy and economy using life cycle assessment approach

The aim of the present study was to evaluate the environmental impacts of hazelnut cultivation in Ordu province of Türkiye, which ranks first in world hazelnut production. Thus, a cradle-to-gate life cycle assessment (LCA) was implemented to analyze the environmental impact potentials determined as acidification potential (AP), eutrophication potential (EP), and global warming potential (GWP). […]

Trend Analysis of Different Climate Parameters and Watering Requirements for Hazelnut in Central Italy Related to Climate Change

In this study, the effects of climate change on the irrigation water requirement of hazelnut trees were investigated in Central Italy. The meteorological variables considered were precipitation, temperature, chilling units, and the Standardized Precipitation Index (SPI) in Central Italy. The hydrological variables were the reference evapotranspiration (ET0) and the water requirement based on soil water […]

Fruit Phenology of Two Hazelnut Cultivars and Incidence of Damage by Halyomorpha halys in Treated and Untreated Hazel Groves

Over the past decade, Halyomorpha halys has become one of the main threats to hazelnut production. Its trophic activity makes kernels inedible due to strongly detrimental effects on the organoleptic quality. Its management in Italy is still tricky due to the lack of effective native biocontrol agents and authorized and effective insecticides. A field test was performed […]

Food-Induced Anaphylaxis: Data From the European Anaphylaxis Registry

Background: Food is one of the most common elicitors of anaphylaxis, with an increasing incidence over recent years. Objectives: To characterize elicitor-specific phenotypes and identify factors enhancing the risk or severity of food-induced anaphylaxis (FIA). Methods: We analyzed data from the European Anaphylaxis Registry applying an age- and sex-matched analysis of associations (Cramer’s V) for single food triggers […]
