Evaluation of the microelement profile of Turkish hazelnut (Corylus avellana L.) varieties for human nutrition and health

In this study; the levels of boron (B); cobalt (Co); copper (Cu); chromium (Cr); iron (Fe); lithium (Li); nickel (Ni); selenium (Se) and zinc (Zn) microelements in 16 hazelnut samples were determined by inductively coupled plasma mass spectrometry and atomic absorption spectroscopy after microwave digestion; and are discussed for human nutrition and health. Significant differences […]

Antioxidant phytochemicals in hazelnut kernel (Corylus avellana L.) and hazelnut byproducts.

Antioxidant efficacies of ethanol extracts of defatted raw hazelnut kernel and hazelnut byproducts (skin; hard shell; green leafy cover; and tree leaf) were evaluated by monitoring total antioxidant activity (TAA) and free-radical scavenging activity tests [hydrogen peroxide; superoxide radical; and 2;2-diphenyl-1-picrylhydrazyl (DPPH) radical]; together with antioxidant activity in a beta-carotene-linoleate model system; inhibition of oxidation […]

Effects of hazelnut-enriched diet on plasma cholesterol and lipoprotein profiles in hypercholesterolemic adult men.

Objective: Frequent consumption of nuts is associated with favorable plasma lipid profiles and reduced risk of coronary heart disease (CHD). This study was conducted to investigate the effects of hazelnut-enriched diet on plasma cholesterol and lipoprotein profiles in hypercholesterolemic adult men compared with baseline and control diet; and also to measure the anthropometric parameters; habitual […]

Enhancement of hazelnut extract for IgE testing by recombinant allergen spiking

Hazelnuts are a common cause of food allergic reactions. Most hazelnut allergic individuals in central and northern Europe are sensitized to Cor a 1; a member of the PR-10 protein family; while the lipid transfer protein Cor a 8 acts as a major allergen in the south of Europe. Other allergens; including profilin and seed […]
