A retrospect study into the utility of allergen components in walnut allergy.
Walnut (Juglans regia) and Pecan (Carya illinoinensis) are members of the Juglandaceae family. Walnut and pecan appear similar and share high protein homology with the result that most walnut allergic individuals are also allergic to pecan nut. Walnut is a common allergy in tree nut allergic individuals in the United States and the United Kingdom […]
Food allergy in children.
Food allergy represents a highly up-to-date and continually increasing problem of modern man. Although being present in all ages, it most often occures in children aged up to three years. Sensitization most often occurs by a direct way, but it is also possible to be caused by mother's milk, and even transplacentally. Predisposition of inadequate […]
Thermal processing effects on peanut allergen Ara h 2 allergenicity in mice and its antigenic epitope structure.
Ara h 2 was purified from peanuts that were thermally treated by various processes, including boiling, glycation, frying and roasting. The allergenicity of Ara h 2 in Balb/c mice and the influence of thermal processing on the structural characteristics, and binding capacity of three core antigenic epitopes were studied. The results demonstrated that boiling, glycation […]
Impact of packaging atmosphere, storage and processing conditions on the generation of phytoprostanes as quality processing compounds in almond kernels.
The thermal processing of almond kernels implies the use of techniques that produce chemical changes such as oxidation. Phytoprostanes (PhytoPs) are considered biomarkers of the oxidative stress in plants. We studied the PhytoP profile in kernels of almond cultivars under different conditions, in relation to packaging, temperature and time of storage and processing. The most […]
Aflatoxins in hazelnuts and dried figs: Occurrence and exposure assessment.
A total of 300 samples of hazelnuts and dried fig were analysed for the incidence of any aflatoxins (AFs). High-performance liquid chromatography coupled with fluorescence detection (HPLC-FLD) method was used to quantify the amounts of AFs. The limit of quantification varied from 0.21 to 0.30μgkg(-1). No AFs were detected in shells of the hazelnuts, while […]
Fatty acids determination in Bronte pistachios by gas chromatographic method.
A gas chromatographic with flame ionization detector (GC-MS FID) method for the identification and quantification of fatty acids based on the extraction of lipids and derivatisation of free acids to form methyl esters was developed and validated. The proposed method was evaluated to a number of standard FAs, and Bronte pistachios samples were used for […]
Consumption of Walnuts in Combination with Other Whole Foods Produces Physiologic, Metabolic, and Gene Expression Changes in Obese C57BL/6J High-Fat-Fed Male Mice.
BACKGROUND: Although a reductionist approach has sought to understand the roles of individual nutrients and biochemicals in foods, it has become apparent that there can be differences when studying food components in isolation or within the natural matrix of a whole food. OBJECTIVE: The objective of this study was to determine the ability of whole-food […]
Pistachios for Health: What Do We Know About This Multifaceted Nut.
Human beings have known about pistachio nuts since 6000 bc. Since then, pistachios have been systematically incorporated into the diet of various cultures. They are nutrient-dense nuts with a healthy nutritional profile that contains fiber, unsaturated fatty acids and antioxidant compounds.
Nuts and their co-products: The impact of processing (roasting) on phenolics, bioavailability, and health benefits – A comprehensive review.
Nuts serve as important healthful snacks worldwide. They are highly desirable due to the presence of numerous essential macro- and micronutrients and health-promoting phenolic compounds (polyphenols). Nuts are usually consumed either as raw (natural) or as roasted. In addition, nuts and their co-products have been demonstrated to be rich sources of phenolic compounds that possess […]
Influence of a Mediterranean Dietary Pattern on Body Fat Distribution: Results of the PREDIMED-Canarias Intervention Randomized Trial.
OBJECTIVE: To assess the influence of a Mediterranean dietary pattern (MeDiet) on anthropometric and body composition parameters in one of the centers of the PREDIMED randomized dietary trial. SUBJECTS/SETTINGS: 351 Canarian free-living subjects aged 55 to 80 years, with type 2 diabetes or ≥3 cardiovascular risk factors. INTERVENTION: Participants were randomly assigned to one of […]
