Cold plasma processing effect on cashew nuts composition and allergenicity.

The study investigated the influence of atmospheric plasma processing on cashew nut composition as well as on its allergenicity. The cashew nuts were processed by low-pressure plasma, using glow discharge plasma (80 W and 50 kHz power supply). Anacardic acids and allergens were quantified by HPLC and immunoassay, respectively. Additionally, the overall composition was evaluated by 1H qNMR. […]

A cashew specific monoclonal antibody recognizing the small subunit of Ana o 3.

Food allergies represent a substantial medical liability and preventing accidental exposure to food allergens requires constant attention. Allergic reaction to cashew nuts is frequently serious, and the small 2S albumin, Ana o 3, is an immuno-dominant cashew allergen. Ana o 3 is composed of five alpha helices, contains 2 subunits linked by cysteine disulfide bonds, and remains soluble even […]

Application of multivariate optimization for the selective extraction of phenolic compounds in cashew nuts (Anacardium occidentale L.).

An extraction method based on a multivariate analytical approach was developed for enhancement of the phenolic compounds in cashew nut extracts. The different extractor solvents (acetone, water, ethanol, and methanol) and their binary, ternary, and quaternary combinations were evaluated using a simplex-centroid design and surface response methodology. The special cubic model exhibits no lack of fit and […]

Nanomaterials Based on Fe3O4 and Phthalocyanines Derived from Cashew Nut Shell Liquid.

In this work we report the synthesis of new hybrid nanomaterials in the core/shell/shell morphology, consisting of a magnetite core (Fe3O4) and two consecutive layers of oleic acid (OA) and phthalocyanine molecules, the latter derived from cashew nut shell liquid (CNSL). The synthesis of Fe3O4 nanoparticle was performed via co-precipitation procedure, followed by the nanoparticle coating with OA […]

Anacardium Plants: Chemical, Nutritional Composition and Biotechnological Applications.

Anacardium plants are native to the American tropical regions, and Anacardium occidentale L. (cashew tree) is the most recognized species of the genus. These species contain rich secondary metabolites in their leaf and shoot powder, fruits and other parts that have shown diverse applications. This review describes the habitat and cultivation of Anacardium species, phytochemical and nutritional composition, and their industrial food […]

Valorisation of Cashew Nut Shell Liquid Phenolics in the Synthesis of UV Absorbers.

With current concerns over the use of fossil resources for chemical synthesis of functional molecules and the effect of current UV absorbers in sunscreens have on the ecosystem, we describe a xylochemical synthesis of different classes of aromatic UV absorbers utilizing cashew nut shell liquid as a non‐edible bio‐renewable carbon source. Hydroxybenzophenones, xanthones, triazines, and […]

A highly sensitive GC‐MS method for simultaneous determination of Anacardic Acids in Cashew (Anacardium occidentale) Nut Shell oil in presence of other phenolic lipid derivatives.

The commercial value of Cashew nut shell liquid (CNSL) has become a corner stone in agro waste industry as it is the by-product of the cashew industry which has 1/8 inch thickness of soft honey comb structure. CNSL contains phenolic lipids with aliphatic chains such as anacardic acid, cardanol, cardol, and methyl cardol, and their derivatives. The developed GC/MS […]

SPT predictive values for the outcome of cashew challenges in children.

BACKGROUND: Cashew is a common cause of tree nut allergy in children. To date there have been few studies of diagnostic tests for cashew allergy, and positive predictive values (PPVs) for cashew as well as other tree nuts are largely extrapolated from studies of peanut allergy. How relevant these cut-offs are for cashew has not […]

Food allergy endotype with high risk of severe anaphylaxis in children-Monosensitization to cashew 2S albumin Ana o 3.

BACKGROUND: Food allergy in children can be life-threatening. Component-resolved diagnostics approach to food anaphylaxis is rarely assessed in children. The aim of the study was to identify the food allergen components as the triggers responsible for severe anaphylaxis, with regard to characteristics and associated risks, among children in a large, population-based setting. METHODS: Two hundred […]
