Undeclared Food Allergens and Gluten in Commercial Food Products Analyzed by ELISA.
Undeclared allergen(s) in commercial food products are responsible for many food recalls, as reported by regulatory agencies in various countries, including the United States. Correct allergen labeling practices are essential for the safety of food-allergic consumers. However, this practice may be hindered by the introduction of allergens all along the food supply chain, including unintentionally […]
Integrating Allergen Analysis Within a Risk Assessment Framework: Approaches to Development of Targeted Mass Spectrometry Methods for Allergen Detection and Quantification in the iFAAM Project.
Allergen analysis is central to implementing and monitoring food allergen risk assessment and management processes by the food industry, but current methods for the determination of allergens in foods give highly variable results. The European Union-funded "Integrated Approaches to Food Allergen and Allergy Risk Management" (iFAAM) project has been working to address gaps in knowledge […]
Self-reported adverse food reactions and anaphylaxis in the SchoolNuts study: A population-based study of adolescents.
BACKGROUND: Adolescents are at the highest risk of death from anaphylaxis, yet few population-based studies have described the frequencies and risk factors for allergic reactions caused by accidental allergen ingestion in this group. METHODS: We describe the prevalence, frequency, and associated risk factors for recent adverse food reactions in 10- to 14-year-olds in Melbourne, Australia, […]
Allergenic food introduction and risk of childhood atopic diseases.
BACKGROUND: The role of timing and diversity of allergenic food introduction in the development of childhood allergic sensitization and atopic diseases is controversial. OBJECTIVE: To examine whether timing and diversity of allergenic food introduction are associated with allergic sensitization, allergy and eczema in children until age 10 years. MATERIALS AND METHODS: This study among 5,202 […]
The allergen-specificity of early peanut consumption and the impact on the development of allergic disease in the LEAP Study Cohort.
BACKGROUND: Early introduction of dietary peanut in high-risk infants with severe eczema and/or egg allergy prevented peanut allergy at 5 years of age in the LEAP Study; the protective effect persisted after 12 months of avoiding peanuts in the LEAP-On Study. It is unclear whether this benefit is allergen and allergic-disease specific. OBJECTIVE: To assess […]
Liquid chromatography coupled to tandem mass spectrometry for detecting ten allergens in complex and incurred foodstuffs.
Food allergy is a considerable heath problem, as undesirable contaminations by allergens during food production are still widespread and may be dangerous for human health. To protect the population, laboratories need to develop reliable analytical methods in order to detect allergens in various food products. Currently, a large majority of allergen-related food recalls concern bakery […]
Tree nut, peanut, and peanut butter intake and risk of postmenopausal breast cancer: The Netherlands Cohort Study.
PURPOSE: Nut intake has been associated with reduced mortality and risk of cardiovascular diseases, but there is only limited evidence on cancer. We investigated the relationship between nut intake and risk of postmenopausal breast cancer, and estrogen/progesterone receptor (ER/PR) subtypes. METHODS: In The Netherlands Cohort Study, 62,573 women aged 55-69 years provided information on dietary and […]
A metabolomics-based approach identifies changes in the small molecular weight compound composition of the peanut as a result of dry-roasting.
Raw peanuts in the USA are subjected to thermal processing, such as dry-roasting, prior to consumption. A multi-instrument metabolomics-based platform along with targeted analyses was used to determine changes in the low-molecular-weight compound composition of peanuts due to dry-roasting. Runner and virginia-type peanut seeds were characterized using several analytical platforms including (RP)/UPLC-MS/MS (positive and negative […]
The effects of different dry roast parameters on peanut quality using an industrial belt-type roaster simulator.
Peanuts roasted to equivalent surface colors at different temperature/time combinations can vary substantially in chemical and physical properties related to product quality. This study used a pilot plant scale roaster that simulates the configurations of one of the most common industrial roaster, a multi-zone belt roaster. Jumbo-size runner-type peanuts were systematically roasted at 5 temperatures […]
Peanuts that keep aflatoxin at bay: A threshold that matters.
Aflatoxin contamination in peanuts poses major challenges for vulnerable populations of sub-Saharan Africa and South Asia. Developing peanut varieties to combat pre-harvest Aspergillus flavus infection and resulting aflatoxin contamination has thus far remained a major challenge, confounded by highly complex peanut-Aspergilli pathosystem. Our study reports achieving high level of resistance in peanut by over expressing […]
