BACKGROUND Component-based diagnosis on multiplex platforms is widely used in food allergy but its clinical performance has not been evaluated in nut allergy. OBJECTIVE To assess the diagnostic performance of a commercial protein microarray in the determination of specific IgE (sIgE) in peanut, hazelnut, and walnut allergy. METHODS sIgE was measured in 36 peanut-allergic, 36 hazelnut-allerg...

Iran has suitable conditions for cultivating high-quality varieties of hazelnuts (Corylus avellana L.). Most of hazelnut orchards in Iran have been established by planting native genotypes. Aspergillus flavus Link. (AF) is a filamentous fungus affecting hazelnut kernels in orchards and during storage conditions. The most widely explored strategy for reducing aflatoxin contamin...

Hazelnut, a very important cash crop in Turkey, is frequently colonized by bark and ambrosia beetle species (Scolytinae). Some scolytine species may cause economic damage while other species do not; therefore, proper identification is important in orchard management. Extensive sampling demonstrated that the most common pest species in Turkey's hazelnut orchards are Anisandrus dispar, Xylosandru...

Türkiye has a big potential of hazelnut residues, especially the husks that is not used for any purposes. It estimated 200.000 tons husk residue produced per year after harvesting. Biomass became very popular since it alternative source energy and provides employment facilities in rural areas. Briquetting most widely waste compaction technology. A hydraulic type briquetting machine with horizon...

  Background:Confirmation of olive oil authenticity and particularly virgin olive oil has a great importance. Several advanced chemical and genetic analyses have been used to monitor especial components; however each has its limitations especially when detecting hazelnut-adulterated olive oil. Objectives:The objective of this research is to assess the presence of trace amoun...

world consumption of butter has declined over the last decades partly due to its physical limitations and partly due to its poor nutritionalproperties. in this study, the effect of hazelnut addition on the properties of butter, was evaluated taking into account that hazelnut is a source of unsaturated fatty acids and antioxidants. powdered hazelnut was added to butter at 3 levels (10, 20 and 30...

Methods nCor a 8 was purified from raw hazelnuts by precipitation and chromatographical steps. Subsequently, the protein was identified by N-terminal sequencing and mass spectrometry. Stability of the protein was investigated by simulated gastric and duodenal digestion assays. Hazelnut lipids were extracted employing the hexane method. Finally, IgE binding activity of native and reduced/alkylat...

Methods Otherwise healthy children with oral food challenge confirmed hazelnut allergy were prospectively evaluated. Crude protein extracts were obtained from 5 hazelnut varieties, including autochthon, Northern Italy and Oregon (USA) cultivars, with phosphate saline buffer, pH 7.2. The immunoreactive protein components were identified by SDS-PAGE electrophoresis and Western immunoblotting, usi...

Methods Thirty-five children (median age: 8.3, range2.2–14.2 yr) reported with immediate reactions to hazelnut ingestion underwent food challenge (DBPCFC) between April 2007 and May 2012. Skin prick test (SPT), specific IgE determination at ImmunoCAP with whole food allergens and with allergen components at ImmunoCAP ISAC microarray chip were performed. The molecular profile of reactivity was c...

Extraction of high quality RNA is a critical step in molecular genetics studies. Hazelnut is one of the most important nuts plants in the world. The presence of the taxol and other taxanes in hazelnut plant necessitates explaining their biosynthesis pathway and identifying the candidate genes. Therefore, an easy and practical method is necessary for RNA extraction from hazelnuts. Hazelnut has h...
