Peanut oleosins associated with severe peanut allergy-Importance of lipophilic allergens for comprehensive allergy diagnostics.

BACKGROUND: Peanut allergy is one of the most common and most severe food allergies in Western countries and its accurate diagnosis to prevent potential life-threatening allergic reactions is crucial. However, aqueous extracts used for routine diagnostic measurements are devoid of lipophilic allergens such as oleosins. We have recently succeeded in the isolation and purification of […]

Update on Timing and Source of ‘Allergenic' Foods.

As the prevalence of food allergies in many communities continues to rise, the question of when in infancy to introduce any solid foods, or specific 'more allergenic' foods, as a food allergy prevention strategy has been debated. Observational studies have found that introducing any solid foods prior to 4 months of age was associated with […]

Free and glycosidically bound volatile compounds in sun-dried raisins made from different fragrance intensities grape varieties using a validated HS-SPME with GC–MS method.

The conditions of sample pretreatments and HS-SPME for extracting volatile compounds from raisins were optimized, and the method was validated in the study. Free and glycosidically bound volatile compounds in three different fragrance intensities raisins were analysed using this method. There were 91 compounds identified, and 72, 26 and 8 of these compounds came from […]

Sun dried Corinthian currant (Vitis Vinifera L., var. Apyrena) simple sugar profile and macronutrient characterization.

Corinthian currant simple sugar profile was determined by high-pressure liquid chromatography coupled with refractive index detection; the content in other macroconstituents was also assessed. Corinthian currants analyzed were obtained over three consecutive crop years, while the effect of cultivation area altitude was also evaluated. Sugar extraction was optimized with respect to solvent, process, and time. […]

A Quantitative Assessment of the Risk of Human Salmonellosis Arising from the Consumption of Almonds in the United States: The Impact of Preventive Treatment Levels.

The presence of Salmonella on almonds continues to result in product-related outbreaks and recalls in the United States. In this study, the impact of microbial reduction treatment levels (1 to 5 log CFU) on the risk of human salmonellosis from the consumption of almond kernels in the United States was evaluated. An exposure model, including […]
