Abstract This paper aims to analyse the participation of a local product in tourism value chain, from supply perspective. Based on qualitative case study, interviews were carried out with hazelnut producers Brunyola, Girona, north-eastern Catalonia. The results showed influences internal and external factors, such as climate change, present future conditions chain context food management market...

Background The high frequency of pollen sensitization has been reported among peanut and tree nuts sensitized patients in our previous study. The antigen homology of peanut and tree nuts antigens with betula was previously shown. However there is a lack of knowledge about the cross-reactivity between hazelnut and grass pollen antigens. The aim of this study is to find out if there is a differen...

A normal-phase high-performance liquid chromatography (NP-HPLC) method for the determination of tocopherols and tocotrienols in hazelnuts is reported. Three extraction procedures (with and without saponification) were assayed; the best results were obtained with a simple solid-liquid extraction procedure. Chromatographic separation was achieved using an Inertsil 5 SI column using isocratic elut...

Pest spillover from wildlands to farms can create conflict between habitat conservation and agricultural production. For example, the key economic pest of hazelnuts in Oregon’s Willamette Valley is filbertworm (Cydia latiferreana), a moth hosted by native Oregon white oak (Quercus garryana). Oak near hazelnut orchards sustain source populations that compound load throughout growing season. This...
