Can pan-allergens affect the sensitization pattern?

The present study tested the hypothesis that a pan-allergen sensitization may affect the sensitization pattern. For this reason, 22 sensitization pattern allergens (SPA), common in Genoa (Italy), were selected for analyses. Successively, five of them, such as Pru p 3 as representative for LTP family, Bet v 1 and Pru p 1 for PR-10, and […]

Review suggests that the immunoregulatory and anti‐inflammatory properties of allergenic foods can provoke oral tolerance if introduced early to infants’ diets.

For years, the advice was to postpone introducing allergenic foods, in order to prevent food allergies. However, food allergies have escalated rather than declined and our review of the latest epidemiological, immunological and nutritional research suggests that early weaning practices may be beneficial. The most allergenic foods, such as fish, eggs and peanuts, have proved […]

Conjunctival provocation test in diagnosis of peanut allergy in children.

BACKGROUND: Peanut allergy frequently cause severe allergic reactions. Diagnosis include detection of IgE to peanuts in serum or by skin prick tests. While children may have allergic sensitisation without having clinical peanut allergy, oral peanut challenge is often required for accurate diagnosis. The conjunctival provocation test is used for diagnosis and evaluation of treatment effect […]

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: […]

Identifying Epithelial Endocytotic Mechanisms of the Peanut Allergens Ara h 1 and Ara h 2.

BACKGROUND: Peanuts are still one of the highest contributors to anaphylactic deaths after ingestion of a food allergen. At the molecular level, interactions between peanut allergens and the intestinal epithelium are largely unexplored. Previous findings by our research group demonstrated that the major peanut allergens, i.e., Ara h 1, Ara h 2, Ara h 3, […]

Streamlining the analytical workflow for multiplex MS/MS allergen detection in processed foods

Allergenic ingredients in pre-packaged foods are regulated by EU legislation mandating their inclusion on labels. In order to protect allergic consumers, sensitive analytical methods are required for detect allergen traces in different food products. As a follow-up to our previous investigations, an optimized, sensitive, label-free LC-MS/MS method for multiplex detection of five allergenic ingredients in […]
