A total of nine specific peptide biomarkers (one from CCA; one each from horse and pig skin gelatin; and two each from sheep, camel, and cow skin gelatin) with good signal responses were screened. After synthesizing these nine specific peptide biomarkers, an ultrahigh-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) multireaction monitoring (MRM) analysis method was established and the limits of specific peptide biomarkers of non-donkey adulterating ingredients content in CCA were proposed. This study established a rapid, simple, highly sensitive, and specific method for the authenticity certification and quality assessment of CCA, ensuring product quality and safety. The method enables identification of specific peptide biomarkers in ass hide glue while simultaneously detecting five adulterated ingredients: sheep, horse, pig, camel, and cattle skins.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"151 ","pages":"Article 108954"},"PeriodicalIF":4.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
