Abstract
Provided herein is a method of authenticating using peptide markers found in edible bird's nest hydrolysate. The method can be used to authenticate edible bird's nest and related products and/or distinguish between white edible bird's nest and grass edible bird's nest.
Claims20
A method of identifying an edible bird's nest (EBN) in a sample suspected of comprising the EBN, the method comprising:
- providing a hydrolysate of the sample;
- analyzing the hydrolysate using a mass spectroscopy method;
- determining whether the hydrolysate comprises one or more peptide markers, wherein the one or more peptide markers have an observed mass to charge ratio (m/z) selected from the group consisting of:
- 277.6012-277.7012 (BNM201), 280.1454-280.2454 (BNM202), 280.6246-280.7246 (BNM203), 292.1148-292.2148 (BNM204), 294.7642-294.8642 (BNM205), 300.0959-300.1959 (BNM206), 305.1166-305.2166 (BNM207), 321.6531-321.7531 (BNM208), 373.7747-373.8747 (BNM209), 381.6542-381.7542 (BNM210), 391.6929-391.7929 (BNM211), 404.1486-404.2486 (BNM212), 410.6669-410.7669 (BNM213), 433.6506-433.7506 (BNM214), 441.6666-441.7666 (BNM215), 454.6518-454.7518 (BNM216), 468.6939-468.7939 (BNM217), 477.6830-477.7830 (BNM218), 498.7467-498.8467 (BNM219), 630.7600-630.8600 (BNM220), 711.3910-711.3910 (BNM221), 820.3134-820.4134 (BNM222), 844.3228-844.4228 (BNM223), 335.1730-335.2730 (BNM224), 417.6510-417.7510 (BNM225), and 447.6496-447.7496 (BNM226);
- and
- identifying based on the whether the hydrolysate comprises the one or more peptide markers if the sample comprises the EBN.
