In this study, some engineering characteristics (physical properties, colour characteristics, coefficients of static friction and mechanical behaviours) the shelled kernel Çakıldak Foşa hazelnut cultivars cultivated in Türkiye were investigated for harvest post applications. The moisture contents 8.69-7.56% (% wet basis) 5.37- 4.64% basis), respectively. Statistically significant (p

BACKGROUND Hazelnut allergy can be a consequence of sensitization to cross-reactive pollen, especially from the Fagales family. However, severe allergic reactions after ingestion of hazelnuts without associated pollen allergy have been reported. In these cases, oral sensitization by hazelnut ingestion is plausible. OBJECTIVE We have reported that antiulcer drugs promote oral sensitization to ...

Literature about the value of diagnostic tests for hazelnut allergy in children is scarce. For peanut allergy cutoff levels of specific IgE with a 95% positive predictive value (PPV) were published. To evaluate current diagnostics for hazelnut allergy in children, data of 151 children, who underwent a double-blind placebo-controlled food challenge (DBPCFC) for hazelnut were analyzed. The PPV or...

Background Hazelnut-allergic children express variable clinical phenotypes. Tests for the diagnosis of hazelnut allergy are usually conducted on children presenting clinical symptoms following hazelnut ingestion, but also as screening tests after the discovery of a food allergy, mainly to tree nut or peanut. It is important to determine if molecular allergens could be markers of severity in haz...

BACKGROUND Although hazelnut consumption is very high in Turkey, the prevalence of hazelnut allergy is still unknown. This study's objective was to investigate the prevalence of hazelnut sensitisation and to verify its clinical importance using double-blind, placebo-controlled challenge (DBPCFC) in an adult population. METHODS Prick-to-prick skin tests were performed with fresh hazelnut in 90...

Hazelnut is an important food resource for the larvae and adults of hazelnut weevil, Curculio nucum. While wormy nuts reflect impact such weevils at harvest time, little known about other types damage they cause. To establish a comprehensive list damages, thereby identify period vulnerability, male female were collected weekly isolated on fruiting branches 1 week. Based nut development, higher ...

BACKGROUND Oral challenges are the gold standard in food allergy diagnostic, but time-consuming. Aim of the study was to investigate the role of peanut- and hazelnut-component-specific IgE in the diagnostics of peanut and hazelnut allergy and to identify cutoff levels to make some challenges superfluous. METHODS In a prospective and multicenter study, children with suspected peanut or hazelnu...

BACKGROUND Sensitization to hazelnut allergens vary depending on the geographic origin and age of the patients. The objective of this study was to further investigate the allergenic activity of hazelnut allergens using sera from patients recruited in various European regions and presenting different sensitization patterns to hazelnut proteins. METHODS Natural Cor a 11 and Cor a 9 were purifie...
