The effect of heat treatment on phenolic compounds and fatty acid composition of Brazilian nut and hazelnut.
Brazilian peanut oil content increased with oven heating (65.08%) and decreased with microwave heating process (61.00%). While the phenolic content of untreated Brazilian nut was the highest of 68.97 mg GAE/100 g. Hazelnut (Sivri) contained the highest antioxidant activity (86.52%, untreated). Results reflected significantly differences between the antioxidant effect and total phenol contents of Brazilian […]
Evaluation of Peroxyacetic Acid for Reducing Low Levels of Salmonella on Laboratory-Inoculated and Naturally Contaminated In-Shell Hazelnuts.
In-shell hazelnuts may be exposed to many sources of Salmonella during harvest and postharvest processing. Chemical sanitizers, such as peroxyacetic acid (PAA), are used by some postharvest processors in an attempt to reduce microbial loads; however, data are limited on its efficacy to reduce Salmonella on in-shell hazelnuts under conditions relevant to the industry. This […]
Effects of Storage Conditions on Consumer and Chemical Assessments of Raw ‘Nonpareil’ Almonds Over a Two‐Year Period.
Raw almonds are a major commodity, yet much is unknown about how storage conditions determine their shelf life. The storage stability, as measured by consumer assessments and chemical measures, of raw almonds was determined for samples stored in cardboard boxes and polypropylene packaging for 2 years at 4, 15, 25, and 35 °C, and at […]
Metabolic fingerprinting of must obtained from sun-dried grapes of two indigenous Cypriot cultivars destined for the production of ‘Commandaria’: A protected destignation of origin product.
Grapes's sun-dried process is one of the most critical steps in the production of 'Commandaria', a dessert wine product that is exclusively produced in Cyprus and derived from must obtained from two indigenous grape cultivars, namely 'Mavro' and 'Xynisteri'. Despite its significant economic importance, no data regarding the primary and secondary metabolites of the aforementioned cultivars […]
Is the Profile of Fatty Acids, Tocopherols, and Amino Acids Suitable to Differentiate Pinus armandii Suspicious to Be Responsible for the Pine Nut Syndrome from Other Pinus Species?
Pinus armandii is suspicious to be responsible for the Pine Nut Syndrome, a long lasting bitter and metallic taste after the consumption of pine nuts. To find chemical characteristic features for the differentiation of P. armandii from other Pinus species, 41 seed samples of the genus Pinus from 22 plant species were investigated regarding the content and the composition of fatty acids, tocopherols, and […]
The classification of almonds (Prunus dulcis) by country and variety using UHPLC-HRMS-based untargeted metabolomics.
The aim of this study was to use an untargeted UHPLC-HRMS-based metabolomics approach allowing discrimination between almonds based on their origin and variety. Samples were homogenized, extracted with ACN:H2O (80:20) containing 0.1% HCOOH and injected in a UHPLC-QTOF instrument in both positive and negative ionization modes. Principal component analysis (PCA) was performed to ensure the […]
Flavor and Acceptance of Roasted California Almonds During Accelerated Storage.
Monitoring oxidative flavor changes in almonds is only possible if the chemical and sensory profile during roasting and storage is first established. Herein almonds roasted at two different temperatures (115 and 152 °C) were stored at 39 °C for 0 to 12 months and were analyzed by Headspace Solid-phase Microextraction Gas Chromatography-Mass Spectrometry (HS-SPME-GC/MS), descriptive analysis and consumer hedonic […]
Should Younger Siblings of Peanut Allergic Children Be Screened for Peanut Allergy?
The role of screening younger siblings of peanut allergic children with allergy testing before peanut introduction is controversial. Although certain guidelines note some value in screening this population, it is not a direct indication in the recent National Institute of Allergy and Infectious Diseases guideline. Some studies suggest that siblings of peanut allergic children are […]
Pine nut allergy in Korean children: Clinical characteristics and diagnostic values of specific IgE against pine nuts.
BACKGROUND: Hypersensitivity reactions to pine nuts in children have been occasionally encountered recently, although reports on pine nut allergy cases are rare worldwide. The study aimed to feature clinical and laboratory findings pertaining to pine nut allergy in Korean children. METHODS: Forty-two subjects were enrolled through a retrospective review of medical records, from September 2010 […]
Diagnostic accuracy, risk assessment, and cost‐effectiveness of component‐resolved diagnostics for food allergy: a systematic review.
BACKGROUND: Component-resolved diagnostics (CRD) are promising tools for diagnosing food allergy, offering the potential to determine specific phenotypes and to develop patient-tailored risk profiles. Nevertheless, the diagnostic accuracy of these tests varies across studies; thus, their clinical utility remains unclear. Therefore, we synthesized the evidence from studies investigating the diagnostic accuracy, risk assessment ability, and […]
