Selection of Pru p 3 hypoallergenic peach and nectarine varieties
Versteeg, Serge A.
To the Editor, Peach is an important fruit consumed worldwide. However, it is also one of the most frequently reported allergenic fruits.1 Component diagnosis of peach allergy indicates Pru p 1, Pru p 2, Pru p 3, Pru p 4, Pru p 7, and Pru p 9 are involved.2, 3 Pru p 3 is the dominant allergen responsible for severe allergic reaction,4 and it is considered to be the primary sensitizer to other LTPs in Mediterranean and Central Europe.5 The levels of Pru p 3 differ between varieties.6 To date, measurement of Pru p 3 in a limited number of peach and nectarines from Spain, United States, and Italy has been reported.7 Significant variation of allergen concentration in processed foods containing peach has also been observed.8 The content of Pru p 3 of peach/nectarine determines the potential risk for peach allergic patients. China is the origin of peach with representative genetic diversity to be explored for hypoallergenic varieties.9 A core collection of 103 varieties cultivated in Jiaxing, Zhejiang Province were selected to represent this diversity, including 23 nectarines and 80 peach varieties (with fruit hair, round or flat, 77 cultivated, three wild) (Table S1). The soluble solid content (SSC), ripening date, and peach aroma intensity were recorded. Specific methods are detailed in the Supporting Information. Pru p 3 was quantified by ELISA based on our previous research.6
