Update on hazelnut allergy: Allergen characterization, epidemiology, food processing technique and detecting strategy
Hazelnuts are popular among people due to their dense nutrient component. However, eating them may be quite dangerous for those who are allergic. To improve food safety, this research examines current developments in the characterization, processing, and detection of hazelnut allergens. The identification and molecular knowledge of certain proteins that cause allergic responses are necessary […]
Integration of Destructive and Non‐Destructive Analytical Determinations for Evaluating Quality of Fresh and Roasted Hazelnuts Subjected to Different Processing Temperatures
The internal quality of hazelnuts (Corylus avellana L.), particularly in terms of the degradation of fat components, is widely recognized as a key factor in determining the appropriate type of industrial processing. Additionally, the internal composition and volatile profile of hazelnuts change significantly based on different roasting conditions. The here reported study investigates the efficiency […]
Advancements and Impacts of Cold Plasma Technology on Dried Nuts and Related Products
In this review, various dried nuts such as almonds, pistachios, peanuts, walnuts, hazelnuts, mixed nuts, and others were subjected to different cold plasma (CP) techniques under varying processing parameters (e.g., voltage, current, frequency, time). The review examines the impact of these treatments on microbial reduction, sensory attributes, and physicochemical properties of the dried nuts. The […]
Comparative analysis of spectroscopic methods for rapid authentication of hazelnut cultivar and origin
Hazelnut market prices fluctuate significantly based on cultivar and provenance, making them susceptible to counterfeiting. To develop an accurate authentication method, we compared the performances of three spectroscopic methods: near infrared (NIR), handheld near infrared (hNIR), and medium infrared (MIR), on over 300 samples from various origins, cultivars, and harvest years. Spectroscopic fingerprints were used […]
Meeting the challenge of varietal and geographical authentication of hazelnuts through lipid metabolite fingerprinting
Hazelnuts are high-quality products with significant economic importance in many European countries. Their market price depends on their qualitative characteristics, which are driven by cultivar and geographical origin, making hazelnuts susceptible to fraud. This study systematically compared two lipidomic fingerprinting strategies for the simultaneous authentication of hazelnut cultivar and provenance, based on the analysis of […]
Hazelnut oral immunotherapy desensitizes hazelnut but not other tree nut allergies (Nut CRACKER Study)
Background: Data on oral immunotherapy (OIT) for hazelnut allergy is limited and its potential to cross-desensitize for other nuts is unknown. Objective: To study the efficacy and safety of hazelnut OIT in desensitizing hazelnut and additional tree nuts. Methods: A prospective observational study of 30 hazelnut allergic patients aged ≥4 years who underwent hazelnut OIT. […]
Effects of Longer-Term Mixed Nut Consumption on Lipoprotein Particle Concentrations in Older Adults with Overweight or Obesity
Background: Recently, we reported that longer-term mixed nut intake significantly reduced serum total and low-density lipoprotein (LDL)-cholesterol, but these markers may not fully capture lipoprotein-related cardiovascular disease (CVD) risk. Objectives: This randomized, controlled, single-blinded, crossover trial in older adults with overweight or obesity examined the effects of longer-term mixed nut consumption on lipoprotein particle size, […]
Study Shows Longer-Term Mixed Nut Consumption May Reduce Cardiovascular Risk in Older Adults
January 16, 2025. This is the third scientific article to emerge from an INC-funded research project Results from a study funded by the International Nut and Dried Fruit Council have been published in the journal Nutrients.[1] The study showed that longer-term consumption of mixed nuts may lower cardiovascular disease (CVD) risk in older adults with […]
Evaluation of the Phenolic Components, Fiber Content, Antioxidant Activity, and Prebiotic Capacity of a Shortbread Cookie Fortified with Hazelnut Skin Waste
Food reformulation is a strategy to make healthier foods by using food waste matrices that are still nutritionally valid. A shortbread cookie was reformulated replacing hazelnut skin (HS) of the Tonda Gentile Romana variety (5% and 10%) to refined flour and proportionally decreasing the butter amount. This resulted in significant, two- and five-fold, increases in […]
Native cover crops enhance biodiversity and ecosystem services in hazelnut orchards
Agroecological restoration aims to restore biodiversity and ecosystem function in agricultural landscapes while sustaining crop production. Adopting native plants as cover crops may restore ecological value to cropping systems such as nut orchards. We focused on Oregon hazelnut orchards and compared how four seed mixes (native annuals, native perennials, conventional cover crops and unseeded controls) […]
