Abstract

is a traditional dish in France that contains 50 to 60% of lipids. The high-fat content of the liver improves the organoleptic qualities of and reduces its technological yield at cooking (TY). As the valorization of the liver as products is strongly influenced by the TY, classifying the in their potential technological quality before cooking them is the main challenge for producers. Therefore, the current study aimed to identify hepatic biomarkers of qualities like liver weight (LW) and TY. A group of 120 male mule ducks was reared and overfed for 6-12 days, and their livers were sampled and analyzed by proton nuclear magnetic resonance (H-NMR). Eighteen biomarkers of qualities were identified, nine for LW and TY, five specific to LW, and four specific to TY. All biomarkers were strongly negatively correlated to the liver weights and positively correlated to the technological yield, except for the lactate and the threonine, and also for the creatine that was negatively correlated to technological quality. As a result, in heavy livers, the liver metabolism was oriented through a reduction of carbohydrate and amino acid metabolisms, and the plasma membrane could be damaged, which may explain the low technological yield of these livers. The detected biomarkers have been strongly discussed with the metabolism of the liver in nonalcoholic steatohepatitis.
