Method for detecting allergen in high oleic acid peanuts by mass spectrometry

PendingCN113514574ASolve the shortcomings of not being able to directly detect allergenic proteinsImprove accuracyComponent separationPeanut food allergyProtein
The invention provides a method for detecting an allergen in high oleic acid peanuts by using mass spectrometry. The method comprises the following steps: performing mass spectrometry on a high oleic acid peanut extract by using a mass spectrometry parallel reaction monitoring method to obtain protein information; comparing and screening the obtained protein information with bioinformatics data in a UniProt database to obtain the allergenic protein related to peanut allergy; and screening out a specific peptide fragment in the sensitization protein through a screening condition. The screening conditions comprise: 1) no modification; 2) the number of spectrums matching the amino acid sequence in the spectrum database is greater than 3; 3) the sequence only exists in one or two proteins; 4) the number of amino acids is 7 to 20; and 5) the peptide fragment does not contain cysteine and methionine. The method can be used for qualitatively and quantitatively detecting the peanut allergenic protein and is relatively high in accuracy; the protein and the peptide fragment can be confirmed, the corresponding peptide fragment can be specifically screened out, and a foundation is laid for subsequently detecting the peanut allergen by using an isotope dilution method.
