Due to its higher price, compared to other edible oils, control of adulteration of the olive oil is one of the main aspects to be evaluated in its quality control. Adulteration with hazelnut oil is one of the most difficult to be detected due to the great similarity existing in the composition of hazelnut and olive oils; both virgin olive oil and olive oil are subjected to that kind of adultera...

BACKGROUND:Raw and roasted nuts are one of the most popular snacks consumed in Iran but mishandling and poor storage conditions and practices may lead to promote the growth of microorganisms and foodborne intoxications and infections. OBJECTIVES:The purpose of this study was to investigate the microbial quality of raw and roasted (salted and unsalt- ed) n...

INTRODUCTION Different clinical and molecular patterns of food allergy have been reported in different areas of the world. The aim of the study is to evaluate differences in allergen patterns among nut-allergic patients in two different areas of Spain. MATERIAL AND METHODS A total of 77 patients with nut allergy from two different regions of Spain (Madrid and Asturias) were evaluated. RESUL...

Halyomorpha halys Stål, the brown marmorated stink bug (Hemiptera: Pentatomidae), is an invasive pest with established populations in Oregon. The generalist feeding habits of H. halys suggest it has the potential to be a pest of many specialty crops grown in Oregon, including hazelnuts, Corylus avellana L. The objectives of this study were to: 1) characterize the damage to developing hazelnut k...

The removal of copper(II) ion from aqueous solution by the granular activated carbon, obtained from hazelnut shells (ACHS) (Corylus avellana L. var. lunga istriana), was investigated. The ACHS was prepared from ground dried hazelnut shells by specific method carbonisation and water steam activation at 950oC for 2 h. The granular activated carbon produced from hazelnut shells has a high specific...

The in vitro bioaccessibility of calcium, iron and zinc of breads added with different bread spreads was determined. The mineral contents were assessed by flame atomic absorption spectrophotometer and expressed in fresh weight (mg/100 g). For the mineral bioaccessibility determination, in vitro gastrointestinal digestion was applied. Among the bread samples, calcium content of wholemeal bread w...

The need to biologically control phytophagous insects has led researchers to consider using microorganisms to control insect pests in the field. On this basis, we decided to conduct field tests to determine the effectiveness of a commercial product made of Beauveria bassiana (Bals.) against the key hazelnut pest Curculio nucum L. Trials were carried out in a hazelnut orchard in the province of ...

Studies on hazelnut (Corylus avellana L.) rootstocks have been limited to date. However, the use of vigorous, non-suckering for this species could increase cost-effectiveness orchards by reducing annual need prune suckers, thus facilitating mechanical harvesting, and orchard management costs environmental impact. Seedlings Turkish tree hazel (C. colurna used traditionally in Serbia. In 1970s, U...

In the Republic of Croatia, hazel (Corylus avellana L.) is fruit species with largest recorded increase in cultivation. Due to its high content lipids and moisture (at time harvest) hazelnuts are susceptible quality deterioration (rancidity development, mycotoxins contamination etc.) therefore proper harvest post-harvest handling necessary preserve their quality. Hazelnuts most often collected ...
