Anti-proliferative profile of Anacardium occidentale polysaccharide and characterization by AFM.
da Silva DA Abstract This paper explores the application of cashew gum (CG) as an in vitro antiproliferative, firstly by isolating and characterizing the gum using elemental analysis, gel-permeation chromatography, nuclear magnetic resonance (NMR) and atomic force microscopy (AFM). The molar mass of isolated CG was in the order of 103-104 g/mol, with small protein traces present. Polymer characterization by NMR identified key signals correlating to galactose, glucose, rhamnose and acid-related groups. Three distinct conformational stages were observed by AFM. The impact of CG on cell morphology and viability wit...

Evaluation of antitumor potential of cashew gum extracted from Anacardium occidentale Linn.
This study aims to determine the antitumor potential of cashew gum in vitro and in vivo. The cashew gum (CG) structure is similar to already showed in literature. The cytotoxicity effect of CG was performed by MTT assay, and B16-F10 melanoma model was used to evaluate antitumor effect. The tumor inhibition was calculated based on tumor weight. Hematological, histopathological, FTIR, oxidative stress and Western Blot analysis were performed to elucidate the mechanism of inhibition and toxic effects. As results, CG did not demonstrate cytotoxicity in vitro, however showed a significant tumor inhibition in vivo, with about 36...

Updated population minimal eliciting dose distributions for use in risk assessment of 14 priority food allergens.
Abstract 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 in 2014. Systematic data collection has continued (2011-2018) and the dataset now contains over 3400 data points. The current study provides new and updated EDp values for 14 allergenic foods and incorporates a newly developed St...

Self-assembling cashew gum-GRAFT-POLYLACTIDE copolymer nanoparticles as a potential amphotericin b delivery matrix.
a RCM Abstract Amphotericin B is an antibiotic used in the treatment of fungal disease and leishmania; however, it exhibits side effects to patients, hindering its wider application. Therefore, nanocarriers have been investigated as delivery systems for amphotericin B (AMB) in order to decrease its toxicity, besides increase bioavailability and solubility. Amphiphilic copolymers are interesting materials to encapsulate hydrophobic drugs such as AMB, hence copolymers of cashew gum (CG) and l-lactide (LA) were synthesized using two different CG:LA molar ratios (1:1 and 1:10). Data obtained revealed that copolymer na...

Molecules, Vol. 25, Pages 954: Changes Induced by Pressure Processing on Immunoreactive Proteins of Tree Nuts
Linacero Tree nuts confer many health benefits due to their high content of vitamins and antioxidants, and they are increasingly consumed in the last few years. Food processing is an important industrial tool to modify allergenic properties of foods, in addition to ensuring safety and enhancing organoleptic characteristics. The effect of high pressure, without and with heating, on SDS-PAGE and immunodetection profile of potential allergenic proteins (anti-11S, anti-2S and anti-LTP) of pistachio, cashew, peanut, hazelnut, almond, and chestnut was investigated. Processing based on heat and/or pressure and ultra-high pre...

Mechanistic insights into acetaminophen removal on cashew nut shell biomass-derived activated carbons.
ova S Abstract Activated carbons prepared from cashew nut shells by chemical activation with phosphoric acid were tested for the removal of acetaminophen. It was found that an increase in carbonization temperature resulted in increased pore volume and decreased amount of surface functional groups. Potentiometric titration analysis indicated that the majority of surface groups on carbons are acidic. Detailed surface characterization by FT-IR, XPS, and thermal analyses indicated the involvement of surface functional groups in the removal of acetaminophen either via hydrogen bonding or by acid hydrolysis. The carbon ...

Tree Nuts Anaphylaxis in Preschool Age Children.
Conclusions. In preschool age children with TNs-FIA, cashew and walnut were the commonest implicated nuts. Most reactions occurred briefly after exposure to minimal amounts of TNs, demonstrating the high potency of these allergens. About one-third also had peanut sensitization. Potentially life-threatening TNs allergy can occur early in childhood and adequate management should be undertaken.

After HA-RF roasting, crude fiber content of kernels increased from 2.49 g/100 g to 3.18 g/100 g while ash and protein content did not change significantly (p > 0.05). In raw and roasted kernels, 14 fatty acids were detected including 7 saturated fatty acids and 7 unsaturated fatty acids. Fatty acid composition and individual amino acid content were not affected by HA-RF or conventional hot air (HA) roasting. MDA content increased from 0.36 mg/kg to 0.48 mg/kg an...

Application of multivariate optimization for the selective extraction of phenolic compounds in cashew nuts (Anacardium occidentale L.).
, Vieira EC Abstract 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 explains 89.2% of the variance. The total phenolic measurements by the Folin-Ciocalteu method revealed the highest values for ethanol (5.93 mg GAE g-1) and acetone-methanol-ethanol ternary mix...

Cashew gum, a biopolymer, topically protects oesophageal mucosa in non erosive reflux disease: a promising translational study
This study aimed to investigate a standardized biopolymer, cashew gum (CG), in human oesophageal mucosa and mice with experimentally-induced non-erosive reflux disease (NERD). Human oesophageal biopsies from NERD patients were collected to evaluate the mucosal protection of CG through transepithelial electrical resistance (TER), mucosal permeability, and mucoadhesiveness tests. A surgical model of NERD in mice was induced, and barrier functions followed by suggestive oesophageal inflammatory hallmarks were evaluated. Pre-coating of CG was effective in human oesophageal mucosa by attenuating drop of TER and mucosal permeabi...

Cold plasma processing effect on cashew nuts composition and allergenicity
Publication date: Available online 19 August 2019Source: Food Research InternationalAuthor(s): Elenilson G. Alves Filho, Lorena Mara A. Silva, Francisco Oiram Filho, Sueli Rodrigues, Fabiano A.N. Fernandes, Maria Izabel Gallão, Christopher P. Mattison, Edy S. de BritoAbstractThe 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, ...

12th IFDC 2017 Special Issue – Foods from Latin America and their nutritional contribution: A global perspective
Publication date: Available online 14 August 2019Source: Journal of Food Composition and AnalysisAuthor(s): Lilia Masson SalaueAbstractBefore the Spaniards conquered America in 1492, several ancient cultures and empires – the Aztec, Maya, Inca, and Mapuche, among them – already inhabited the two continents and had made important advances in the arts and sciences as well as in architecture, astronomy, agriculture and the domestication of crops. These peoples lived according to their own rules and in harmony with their magnificent natural setting. More than 500 years have passed, and Latin America still hosts sig...
