Design and Development of Spray-Dried Microsystems to Improve Technological and Functional Properties of Bioactive Compounds from Hazelnut Shells.
An extract obtained from hazelnut shells by-products (HSE) has antioxidant and chemopreventive effects on human melanoma and cervical cancer cell lines, inducing apoptosis by caspase-3 activation. A clinical translation is limited by poor water solubility and low bioavailability. Dried plant extracts often show critical characteristics such as sticky/gummy appearance, unpleasant smell, and instability involving practical […]
Effect of Drying Temperature and Exposure Times on Aspergillus Flavus Growth and Aflatoxin Production on Artificially Inoculated Hazelnuts.
Aspergillus flavus may colonise hazelnuts and produce aflatoxins in field and during storage. The main purpose of this study was to investigate the influence of drying temperature and exposure times on the viability and ability of A. flavus to produce aflatoxins during the drying process and storage. Hazelnuts were inoculated with A. flavus and dried […]
Updated population minimal eliciting dose distributions for use in risk assessment of 14 priority food allergens.
Food allergy and allergen management are important global public health issues. In 2011, the first iteration of our allergen threshold database (ATDB) was established based on individual NOAELs and LOAELs from oral food challenge in roughly 1750 allergic individuals. Population minimal eliciting dose (EDp) distributions based on this dataset were published for 11 allergenic foods […]
Tree Nuts Anaphylaxis in Preschool Age Children.
Introduction. The incidence of food-induced anaphylaxis (FIA) is increasing in young children. Although the commonest culprits are cow's milk and egg, FIA to tree nuts (TNs) have been increasing. Objective. Characterization of children referred to our allergy department due to TNs-induced anaphylaxis (TNs-FIA) during preschool age. Materials and methods. We have retrospectively included 25 children […]
Physical, Barrier, Mechanical, and Biodegradability Properties of Modified Starch Films with Nut By-Products Extracts.
Starch-based films with phenolic extracts could replace the use of petroleum-based plastics. In this study, octenyl succinate starch (OSS) films with pecan nutshell extract (PSE) or hazelnut skin extract (HSE) were prepared. The water resistance, as well as the optical, physical, mechanical, and biodegradable properties of these films, were investigated. The PSE and HSE improved […]
Dietary Fibre Profiles of Turkish Tombul Hazelnut (Corylus avellana L.) and Hazelnut Skin.
Dietary fibre (DF) profiles of natural hazelnut, roasted hazelnut and hazelnut skin were analyzed. Insoluble (IDF) and soluble (SDF) DFs were examined for monosaccharide and glycosyl-linkage compositions using gas chromatography-mass spectrometry (GC-MS). Total DF contents of natural hazelnut, roasted hazelnut, and hazelnut skin were 17.8, 15.4, and 69.8%, respectively; majority of which (>96%) were water-insoluble. […]
IgE cross-reactivity measurement of cashew nut, hazelnut and peanut using a novel IMMULITE inhibition method.
Background Tree nut-allergic individuals are often sensitised towards multiple nuts and seeds. The underlying cause behind a multi-sensitisation for cashew nut, hazelnut, peanut and birch pollen is not always clear. We investigated whether immunoglobulin E antibody (IgE) cross-reactivity between cashew nut, hazelnut and peanut proteins exists in children who are multi-allergic to these foods using […]
Multi-model subseasonal forecasts of spring cold spells: potential value for the hazelnut agribusiness.
Producing probabilistic subseasonal forecasts of extreme events up to six weeks in advance is crucial for many economic sectors. In agribusiness, this time-scale is particularly critical because it allows for mitigation strategies to be adopted for counteracting weather hazards and taking advantage of opportunities. For example, spring frosts are detrimental for many nut trees, resulting […]
The Inorganic Component as a Possible Marker for Quality and for Authentication of the Hazelnut’s Origin.
The inorganic component of hazelnuts was considered as a possible marker for geographical allocation and for the assessment of technological impact on their quality. The analyzed samples were Italian hazelnuts of the cultivar Tonda Gentile Romana and Turkish hazelnuts of the cultivars Tombul, Palaz and Çakildak. The hazelnuts were subjected to different drying procedures and different conservative methods. The concentration of […]
Critical review on proteotypic peptide marker tracing for six allergenic ingredients in incurred foods by mass spectrometry.
Peptide marker identification is one of the most important steps in the development of a mass spectrometry (MS) based method for allergen detection, since the robustness and sensitivity of the overall analytical method will strictly depend on the reliability of the proteotypic peptides tracing for each allergen. The European legislation in place issues the mandatory […]
