The effect of heat treatment on phenolic compounds and fatty acid composition of Brazilian nut and hazelnut.

Brazilian peanut oil content increased with oven heating (65.08%) and decreased with microwave heating process (61.00%). While the phenolic content of untreated Brazilian nut was the highest of 68.97 mg GAE/100 g. Hazelnut (Sivri) contained the highest antioxidant activity (86.52%, untreated). Results reflected significantly differences between the antioxidant effect and total phenol contents of Brazilian […]

Evaluation of Peroxyacetic Acid for Reducing Low Levels of Salmonella on Laboratory-Inoculated and Naturally Contaminated In-Shell Hazelnuts.

In-shell hazelnuts may be exposed to many sources of Salmonella during harvest and postharvest processing. Chemical sanitizers, such as peroxyacetic acid (PAA), are used by some postharvest processors in an attempt to reduce microbial loads; however, data are limited on its efficacy to reduce Salmonella on in-shell hazelnuts under conditions relevant to the industry. This […]

Diagnostic accuracy, risk assessment, and cost‐effectiveness of component‐resolved diagnostics for food allergy: a systematic review.

BACKGROUND: Component-resolved diagnostics (CRD) are promising tools for diagnosing food allergy, offering the potential to determine specific phenotypes and to develop patient-tailored risk profiles. Nevertheless, the diagnostic accuracy of these tests varies across studies; thus, their clinical utility remains unclear. Therefore, we synthesized the evidence from studies investigating the diagnostic accuracy, risk assessment ability, and […]

Prediction of the severity of allergic reactions to foods.

BACKGROUND: There is currently considerable uncertainty regarding what the predictors of the severity of diagnostic or accidental food allergic reactions are, and to what extent the severity of such reactions can be predicted. OBJECTIVE: To identify predictors for the severity of diagnostic and accidental food allergic reactions and to quantify their impact. METHODS: The study […]

A critical approach to the toxic metal ion removal by hazelnut and almond shells.

The adsorption capacity of ground hazelnut (HS) and almond (AS) shells towards Pb(II) and Cd(II) has been studied at pH = 5, in NaNO3 and NaCl ionic media, in the ionic strength range 0.05-0.5 mol L-1. Kinetic and equilibrium experiments were carried out by using the Differential Pulse Anodic Stripping Voltammetry technique to check the amount of the metal ion removed by […]

Simultaneous Analysis of Multiple Allergens in Food Products by LC-MS/MS.

There is currently no cure for food allergies, and sufferers can only rely on the correct labeling of foods toavoid allergens. Hence, it is important that analytical methods are sensitive and accurate enough to screen for the presence of multiple allergens in food products. In this study, we developed an LC-tandem MS method that is […]

Undeclared Food Allergens and Gluten in Commercial Food Products Analyzed by ELISA.

Undeclared allergen(s) in commercial food products are responsible for many food recalls, as reported by regulatory agencies in various countries, including the United States. Correct allergen labeling practices are essential for the safety of food-allergic consumers. However, this practice may be hindered by the introduction of allergens all along the food supply chain, including unintentionally […]

Integrating Allergen Analysis Within a Risk Assessment Framework: Approaches to Development of Targeted Mass Spectrometry Methods for Allergen Detection and Quantification in the iFAAM Project.

Allergen analysis is central to implementing and monitoring food allergen risk assessment and management processes by the food industry, but current methods for the determination of allergens in foods give highly variable results. The European Union-funded "Integrated Approaches to Food Allergen and Allergy Risk Management" (iFAAM) project has been working to address gaps in knowledge […]

Almond, hazelnut and walnut, three nuts for neuroprotection in Alzheimer’s disease: a neuropharmacological review of their bioactive constituents.

An increase in the prevalence of Alzheimer's disease (AD) as a multifactorial neurodegenerative disorder is an almost obvious issue in the world. Researches on natural products for finding effective drugs to prevent the disease are in progress. There is special attention to the three types of nuts including almond, hazelnut and walnut in manuscripts of […]
