Association of Clinical Reactivity with Sensitization to Allergen Components in Multifood-Allergic Children.

BACKGROUND: Thirty percent of children with food allergies have multiple simultaneous allergies; however, the features of these multiple allergies are not well characterized serologically or clinically. OBJECTIVE: We comprehensively evaluated 60 multifood-allergic patients by measuring serum IgE to key allergen components, evaluating clinical histories and medication use, performing skin tests, and conducting double-blind, placebo-controlled food […]

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 […]

An on-site, ultra-sensitive, quantitative sensing method for the determination of total aflatoxin in peanut and rice based on quantum dot nanobeads strip.

An on-site, ultra-sensitive, and quantitative sensing method was developed based on quantum dot nanobeads (QDNBs) and a test strip for the determination of total aflatoxins (AFTs) in rice and peanuts. The monoclonal antibody against AFT (mAbAFT) was homemade and labeled with QDNB. After the pre-coating of the AFT antigen on the test line (T line), […]

Early introduction of peanuts.

Peanut allergy is the most common food allergy and the leading cause of anaphylaxis and death due to food allergy. Despite previous guidelines created by the American Academy of Pediatrics in 2003, peanut allergy has continued to significantly increase over the past decade. Therefore, further research has been done to help clinicians provide more evidence-based […]

Influence of japanese consumer gender and age on sensory attributes and preference (A case study on deep-fried peanuts).

BACKGROUND: Detailed exploration of sensory perception as well as preference across gender and age for a certain food is very useful for developing a vendible food commodity related to physiological and psychological motivation for food preference. Sensory tests including color, sweetness, bitterness, fried peanut aroma, textural preference, and overall liking of deep-fried peanuts were carried […]

Rapid Characterization of Trace Aflatoxin B1 on Groundnuts, wheat and maize by Dispersive Liquid‐Liquid Microextraction Followed by Direct Electrospray Probe Tandem Mass Spectrometry.

RATIONALE: Aflatoxins are poisonous and cancer-related chemical compounds commonly existed in crops and plants. Aflatoxin B1 is the most toxic compound among aflatoxins and has been classified as Group 1 carcinogenic to human, especially on liver cancer. Herein, an ambient mass spectrometric method was developed for rapid characterization of trace aflatoxin B1 on peanuts. METHODS: […]
