Clinically and Industrially Relevant Peanut Reference Materials to Improve Analysis of Food Allergens

Food allergy requires effective food allergen analysis to support risk analysis and risk management. There are acknowledged shortcomings in allergen analysis which could be better addressed by appropriate reference materials (RM). An RM for peanut has been developed based on a matrix and a partially defatted light roasted peanut flour used for the EuroPrevall clinical threshold studies. The RM has been prepared as a matrix devoid of peanut and the matrix spiked with peanut flour at the clinically relevant concentration of 10 mg kg-1 peanut protein. The partially defatted light roasted peanut flour is also available as a RM. Homogeneity and stability have been characterised and statistically assessed as fit-for-purpose. Establishing the homogeneity of the incurred RM was challenging owing to the dispersion of the data obtained using ELISA. The material is available and presents a model for food allergen RM production, characterisation and curation.
