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 […]
The potential of almonds, hazelnuts, and walnuts SFE-CO2 extracts as sources of bread flavouring ingredients
Nuts have been part of the human diet since our early ancestors, and their use goes beyond nutritional purposes, for example, as aromatic sources for dairy products. This work explores the potential of almond (Prunus dulcis (Mill.) DA Webb), hazelnut (Corylus avellana L.), and walnut (Juglans regia L.) extracts as sources of food flavouring agents, […]
Characterization of phenolic constituents in hazelnut kernels
Hazelnuts contain biologically active phenolic compounds and are widely used for their nutritional value. In this study, the phenolic compounds contained in hazelnuts were isolated from the kernels of Corylus avellana L. and investigated. Spectral analyses revealed two new acetophenone glycosides, characterized as 2′,4′,6′-trihydroxyacetophenone 4′-O-(2-O-β-D-apiosyl)-β-D-glucoside and 2′,4′,6′-trihydroxyacetophenone 4′-O-(2-O-β-D-apiosyl-6-O-α-L-arabinosyl)-β-D-glucoside, and four known compounds. Four high-molecular mass […]
Analysis of the Antioxidant Activity, Lipid Profile, and Minerals of the Skin and Seed of Hazelnuts (Corylus avellana L.), Pistachios (Pistacia vera) and Almonds (Prunus dulcis)—A Comparative Analysis
Nuts are dry, single-seeded fruits with a combination of beneficial compounds that aid in disease prevention and treatment. The aims of this research are to evaluate the total antioxidant activity (AI) by ferric reducing antioxidant power (FRAP) assay, fatty acids by acid-catalyzed esterification method, and minerals by inductively coupled plasma optical emission (ICP-OE) spectrometer in […]
Evaluating heavy metal pollution risks and enzyme activity in soils with intensive hazelnut cultivation under humid ecological conditions
In order to promote sustainable agriculture and ensure food security, it has become more vital to identify the causes of soil pollution in agricultural areas. This study was carried out in order to determine the danger of heavy metal contamination in hazelnut production areas and to take the appropriate actions in accordance with the study’s […]
Natural History of Hazelnut Allergy and Current Approach to Its Diagnosis and Treatment.
Hazelnut allergy is the most prevalent type of nut allergy in Europe, with symptoms that can range from mild, such as hives and itching, to severe, such as anaphylaxis, particularly in patients who are sensitized to highly stable allergens, such as storage proteins. Compared to other types of food allergies, allergies to tree nuts, including […]
Valorisation of hazelnut by-products: current applications and future potential.
Hazelnut is one of the most widely consumed nuts around the world. Considering the nutritional value of hazelnuts, a wide range of hazelnut-based food products are available in the market such as oil, chocolate, confectionery, etc. Nevertheless, the processing of hazelnuts generates a large number of by-products and waste. The most valuable by-products of the […]
