The assessment of commercial beef and chicken bouillons in terms of heterocyclic aromatic amines and some of their precursors

Herein, the assessment of commercial beef and chicken bouillons in terms of heterocyclic aromatic amines (HAAs) and some of their precursors was evaluated. Creatine and creatinine levels were ranged between 0.57-0.80 and 0.28-0.94 mg g(-1), respectively. Glutamic acid was found to be the most abundant amino acid in both bouillons. 2-amino-3,7,8-trimethylimidazo[4,5-integral]quinoxaline (7,8-DiMeIQx, up to 0.03 ng g(-1)) was the only quantified analyte in beef bouillons, whereas it (up to 0.08 ng g(-1)) was determined in addition to 2-amino-3-methylimidazo[4,5-integral]quinoxaline (IQx, up to 0.08 ng g(-1)) in chicken bouillons. Creatine, creatinine and free amino acid composition did not have the capacity to initiate the formation of HAAs. Therefore, bouillons do not pose risk in terms of HAAs. However, it should be noted that multiple factors, such as the substrate amount and production conditions, may affect the results. Glutamic acid content is remarkable in commercial bouillons sold in Turkey.
