“…Now there is a popular cookery of mutton in China that we call the food mutton shashlik which can be ordered in most restaurants. High temperature, the essential condition of this cookery, can lead to the formation of heterocyclic amines (HAs), especially heterocyclic aromatic amines (HAAs), in heated meat (Bermudo, Ruiz-Calero, Puignou, & Galceran, 2005;Borgen & Skog, 2004;Busquets, Bordas, Toribio, Puignou, & Galceran, 2004;Martín-Calero, Ayala, González, & Afonso, 2007). Although only trace amounts (ng/g) of these compounds are formed, they are still considered a risk factor for human cancer due to their frequent intake.…”
