The COMprehensive Protein Allergen REsource is a new transparent resource for the identification of protein sequences that are known or putative allergens.  It is created via the development of an automated “rule-based” sorting algorithm tool, combined with a review of the literature associated with the identified sequences.  An independent peer-review panel of allergy experts exclusively from the public sector decides on the final content of the database. These three rigorous and well documented processes have been carefully designed to meet the needs for allergy safety assessment. The combination of these three processes has resulted in the new COMPARE database released on 03 February 2017. The database includes a comprehensive repository of all known allergens, with the addition of newly identified allergens. The cycle will repeat annually for regular updates. This approach will:

1) Identify new listings of candidate allergen sequences.

2) Identify published literature linked to the identified potential allergens. 

3) Verify that the newly identified sequences have clinical evidence of allergenicity based on standardized criteria.


Program Structure

The COMPARE database is a collaborative effort of the HESI (Health and Environmental Sciences Institute) Protein Allergenicity Technical Committee (PATC). The PATC is a public-private collaboration of scientists with a shared interest in improving the assessment of allergenicity in the context of safety evaluation of novel food and feed proteins.

The COMPARE team combines programmatic support from the Joint Institute for Food Safety and Nutrition (http://jifsan.umd.edu) at the University of Maryland, and significant in-kind support from multiple academic, government and industry scientists with expertise in protein allergenicity. This public-private HESI collaborative team will document database design and search algorithm decisions on this website.  On an annual basis, an external expert panel will review protein sequences identified as potential allergens using peer-reviewed publications to determine if they meet criteria for inclusion in the database. The expert panel will document the supporting data for each verified allergen; each allergen will then become included in the COMPARE database. Both the process and the finalized, annually updated COMPARE database will be publicly available on this website.

About HESI

HESI, the Health and Environmental Sciences Institute, is a non-profit, global scientific organization dedicated to developing science for a safer, more sustainable world. 

HESI’s mission is to collaboratively identify and help to resolve global health and environmental challenges through engagement of scientists from academia, government, industry, NGOs, and other strategic partners.

HESI was established in 1989 as a global branch of the International Life Sciences Institute (ILSI) to provide an international forum to advance the understanding of scientific issues related to human health, toxicology, risk assessment, and the environment. In 2002, HESI was recognized by the United States government as a publicly supported, tax-exempt organization, independently chartered from ILSI.
