Cocoa, hazelnuts, sterols and soluble fiber cream reduces lipids and inflammation biomarkers in hypertensive patients: a randomized controlled trial
Effects of Roasting on Antioxidant Status and Phenolic Profiles of Commercial Turkish Hazelnut Varieties (Corylus avellana L.).
The effect of roasting on antioxidant status and phenolic profiles of seven commercial Turkish hazelnut varieties (namely (Ãakildak; Fosa; Karafindik; Mincane; Palaz; Sivri; and Tombul) was assessed. Samples were examined for their total phenolics; oxygen radical absorbance capacity (ORAC) values; condensed tannins; and phenolic acids (free and bound forms). Significant losses (p < 0.05) in […]
Maintaining the quality of unripe; fresh hazelnuts through storage under modified atmospheres.
Unripe hazelnuts are used for fresh consumption due to their delicate taste; the tenderness of the kernel and the fact that they are easy to shell manually without having to use tools. This report focuses on the possibility of storing unripe; fresh hazelnuts (Corylus avellana L.; cv. Tonda Gentile Romana) under modified atmospheres; with the […]
Allergy to hazelnut in adults: A two-step study
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 904 patients […]
Polyphenolic Composition of Hazelnut Skin
Skins from different hazelnut samples were characterized for total polyphenol content; total antioxidant capacity (TAC); and their content in specific polyphenolic compounds. The main polyphenolic subclass; identified and quantified by means of HPLC-MS/MS; comprised monomeric and oligomeric flavan-3-ols; which accounted for more than 95% of total polyphenols. Flavonols and dihydrochalcones were 3.5% while phenolic acids […]
Current guidelines for nut consumption are achievable and sustainable: a hazelnut intervention
Nuts are known for their hypocholesterolaemic properties; however; to achieve optimal health benefits; nuts must be consumed regularly and in sufficient quantity. It is therefore important to assess the acceptability of regular consumption of nuts. The present study examined the long-term effects of hazelnut consumption in three different forms on 'desire to consume' and 'overall […]
Detection of contaminated hazelnuts and ground red chili pepper flakes by multispectral imaging
Mycotoxins are the toxic metabolites of certain filamentous fungi and have been demonstrated to cause various health problems in humans; including immunosuppression and cancer. Among them; the aflatoxins have received greater attention because they are potent carcinogens and are responsible for many human deaths per annum; mostly in non-industrialized countries. Various regulatory agencies have enforced […]
Characterisation of selected hazelnut cultivars: phenology; growing and yielding capacity; market quality and nutraceutical value
Abstract BACKGROUND: Sixteen hazelnut cultivars growing in the continental climate of Slovenia were analysed over 15 years for their phenology; growth habit; yield potential; susceptibility to hazelnut weevil and the pomological traits and phenolic content of their nuts in order to obtain a complex value of these cultivars for growers; the confectionary industry and consumers. […]

Effects of different forms of hazelnuts on blood lipids and a-tocopherol concentrations in mildly hypercholesterolemic individuals
BACKGROUND/OBJECTIVES: Diets high in nuts reduce cholesterol; probably due to their favorable lipid profile and other bioactive substances. However; the physical form of the nut may be important as the cell wall of intact nuts may limit the hypocholesterolemic effect of nuts by reducing lipid bioavailability. Therefore; we investigated the effects on blood lipids of […]
