Peanut and hazelnut occurrence as allergens in foodstuffs with precautionary allergen labeling in Canada.

Precautionary allergen labeling (PAL) is widely used by food industries. Occurrence studies revealed that few analyzed products contained the allergen(s) present in the statement, but little is known in Canada. To improve manufacturing practices and better manage allergen cross-contamination, occurrence data is needed to determine the exposure of allergic individuals eating those products. Samples were […]

An Evaluation of the Impact of the Amount of Potassium Hydroxide on the Porous Structure Development of Activated Carbons.

This paper presents the results of an evaluation of the impact of the amount of potassium hydroxide on the obtained porous structure of the activated carbons derived from the shells of pistachios, hazelnuts, and pecans by carbonization and subsequent chemical activation with potassium hydroxide by different adsorption methods: Brunauer-Emmett-Teller, Dubinin-Raduskevich, the new numerical clustering-based adsorption […]

Adsorption of U (VI) from aqueous solution by using KMnO 4-modified hazelnut shell activated carbon: characterisation and artificial neural network modelling.

This study is based on U(VI) removal from wastewater by KMnO4-modified hazelnut shell activated carbon (KM-HSAC) using adsorption technology. A characterisation study of KM-HSAC was conducted through scanning electron microscope and energy-dispersive X-ray spectroscopy (EDS) analysis. The rough surface of KM-HSAC contains many irregular microspores. The EDS pattern confirmed the U(VI) adsorption on the KM-HSAC. […]

Whole-genome assembly of Corylus avellana cv'Tonda Gentile delle Langhe' using linked-reads (10X Genomics).

The European hazelnut (Corylus avellana L.; 2n=2x=22) is a worldwide economically important tree nut that is cross-pollinated due to sporophytic incompatibility. Therefore, any individual plant is highly heterozygous. Cultivars are clonally propagated using mound layering, rooted suckers and micropropagation. In recent years, the interest in this crop has increased, due to a growing demand related […]

A comprehensive review on different classes of polyphenolic compounds present in edible oils.

Edible oils are used as a frying medium and in the preparation of several food products. They are mainly constituting triacylglycerols as major components, while other compounds are classified as minor constituents, which include polyphenols. This class of compounds plays an important role in the thermal stability and quality attributes of the finished industrial food […]

ImmunoCAP ISAC in food allergy diagnosis: a systematic review of diagnostic test accuracy

The aim of this systematic review is to assess the diagnostic test accuracy of the component-resolved diagnosis device ImmunoCAP ISAC, compared with oral food challenge. Systematic review reported according to the PRISMA-DTA recommendations. Medline, Embase and Cochrane Library databases were searched from inception to May 2019 and updated in March 2021. We included diagnostic test […]

Chemical Composition of the Hazelnut Kernel (Corylus avellana L.) and Its Anti-inflammatory, Antimicrobial, and Antioxidant Activities

The chemical composition of hazelnut kernels (Corylus avellana L.) and their COX-2 inhibitory, antimicrobial, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical-scavenging activities were investigated. Six previously undescribed indoleacetic acid glycosides, hazelnutins A-F (1-6), and five known compounds (7-11) were isolated from the hazelnut kernels. The structures of compounds 1-6 were successfully identified by high-resolution-electrospray […]

Progression of Kernel Mold on Hazelnut

Hazelnut kernel mold, caused by a number of fungal species, has been a chronic problem in Pacific Northwest hazelnut production areas for many years. Two highly susceptible breeding selections and two commercial cultivars were used to investigate kernel mold development over time and possible correlations with rainfall. Nuts were allowed to naturally fall onto orchard […]
