Background: Precautionary allergen labeling (PAL) is mandatory and legally regulated in Korea. This study aims to investigate the frequency of PAL use in food products, evaluate its competence, and seek direction for improvement.
Methods: Cow's milk (CM) and hen's egg white (EW) protein concentrations were measured using an enzyme-linked immunosorbent assay (ELISA). The results validated PAL using the Voluntary Incidental Trace Allergen Labeling 3.0 program. A survey was conducted on guardians to compare preferences and understanding of the current and the arbitrarily revised PAL.
Results: PAL was used in 91.8% (280/305) of baby food products. ELISA results using randomly selected baby food products showed that only 16.7% (5/30; No PAL with no contamination, n = 4; PAL with real-contamination risk, n = 1) were validated to PAL. A detectable CM was found in two products (2/26, 7.7%), with one product exceeding the reference dose (10.3 ± 0.17 ppm). EW was not detected at all (0/16). A total of 207 surveys from guardians were collected and categorized into three groups: food allergy (FA, n = 103), diseases other than food allergies (Others, n = 52), and no disease (Control, n = 52). The FA group exhibited the highest frequency of checking food allergen labeling ("always": 78.6%, "often": 9.7%), with a similar PAL adherence ("always": 58.3%, "often": 10.4%). None of the groups were satisfied with the current PAL. The 'allergen-free' statement was mostly preferred across all groups. The FA group notably preferred PAL with concentration statements.
Conclusion: PAL is excessively prevalent and insufficient in ensuring the safety of children with FAs, necessitating a revision towards a more patient-friendly, evidence-based system for affected individuals and their families.

Rice milk is known for its wide range of beneficial effects on human health. Despite an increasing inclination towards rice drinks consumption, not much is known regarding the protein composition of commercial rice beverages. Hence, using a label-free quantitative proteomics approach we analyzed 9 different commercially available rice drinks and identified 259 rice proteins and 4 exogenous microbial α-amylases.

Background: Peanut allergy (PA) is one of the most prevalent food allergies with a lack of favorable safety/efficacy treatment. A cucumber mosaic virus-like particle expressing peanut allergen component Ara h 2 (VLP Peanut) has been developed as a novel therapeutic approach for PA.
Objective: We assessed the tolerogenic properties and reactivity of VLP Peanut.

Background: Henna is a powdered plant material traditionally used for medicinal and cosmetic purposes in Asia and the Mediterranean region. In North America and Europe, however, it is only used to colour the hair and decorate the body. This colouring process is due to the action of the secondary metabolite lawsone, which enables henna to produce orange to red shades of colour.

Ovalbumin (OVA) is a high-risk allergen with complex tertiary structure in food samples. Here, we developed an accurate UPLC-MS/MS-based assay to improve OVA quantitative performance in processed foods. Full-length isotope-labeled OVA proteins (OVA-I) were synthesized using stable isotope labeling by amino acids in cell culture (SILAC) technique and employed as functional internal standards to ensure similar cleavage sites between internal standards and analytes.

Excipients have been identified as 'inert' substances that often enhance the non-pharmacological aspects of a medication. However, recent clinical evidence elucidates their potential in inducing anaphylaxis and indicates that they are often overlooked as potential allergens in routine clinical practice. The aim of the study was to assimilate published evidence on excipient-induced allergies associated with the use of oral medications and to underline their potential as potent allergens.
