The component-specific to total IgE ratios do not improve peanut and hazelnut allergy diagnoses.

BACKGROUND: Specific IgE measurement predicts the outcome of oral food challenges with considerable uncertainty when evaluating food allergy. OBJECTIVE: Our aim was to assess whether accounting for the ratio of component- or allergen-specific to total IgE can improve this prediction. METHODS: This multicenter study collected blood samples from children with suspected peanut or hazelnut allergy […]

Energy compensation and nutrient displacement following regular consumption of hazelnuts and other energy-dense snack foods in non-obese individuals.

PURPOSE: Regular nut consumption reduces cardiovascular disease risk, partly from improvements to dietary quality. Examining how individuals make dietary changes when consuming nuts may reveal key behavioural eating patterns beneficial for the development of dietary interventions. We examined the effects of nuts in comparison with other energy-dense snacks on energy compensation, nutrient displacement, and food […]

Bioavailability assessment of essential and toxic metals in edible nuts and seeds.

Bioavailability of essential and toxic metals in edible nuts and seeds has been assessed by using an in vitro dialyzability approach. The samples studied included walnuts, Brazil nuts, Macadamia nuts, pecans, hazelnuts, chestnuts, cashews, peanuts, pistachios and seeds (almond, pine, pumpkin and sunflower). Metals were measured by inductively coupled plasma-mass spectrometry in dialyzates and also […]

Development and inter-laboratory transfer of a decaplex polymerase chain reaction assay combined with capillary electrophoresis for the simultaneous detection of ten food allergens.

Food allergies cause health risks to susceptible consumers and regulations on labeling of food allergen contents have been implemented in many countries and regions. To achieve timely and accurate food allergen labeling, the development of fast and effective allergen detection methods is very important. Herein, a decaplex polymerase chain reaction (PCR) assay combined with capillary […]

Non-destructive detection of flawed hazelnut kernels and lipid oxidation assessment using NIR spectroscopy.

Microbial contamination, seed browning, bad taste and lipid oxidation are primary causes of quality deterioration in stored hazelnuts, affecting their marketability. The feasibility of NIR spectroscopy to detect flawed kernels and estimate lipid oxidation in in-shell and shelled hazelnuts was investigated. ‘Mortarella’ hazelnuts were measured twice by NIR spectroscopy, first in-shell, and then as kernels. […]

Effect of MW-assisted roasting on nutritional and chemical properties of hazelnuts.

In order to enhance the flavor, texture, color, and appearance of hazelnuts, they are roasted during postharvest processing. In this study, raw hazelnuts (Corylus avellana L.) were roasted using microwave (MW) and MW-assisted hot air methods under various roasting conditions. The hazelnuts roasted were then examined to determine the percent DPPH radical scavenging activity, antioxidant […]
