NIR and Vis-NIR spectroscopy to predict PSE-like zones of ham

PSE-like zones are still a major concern for the meat processing industry. This structure defect of the ham is known to increase slicing losses of the phosphate-free “Jambon Cuit Supérieur” processing. PSE-like zones are difficult to detect before deboning due to their localization on the inside surface of the ham. Near Infra-Red Spectroscopy (NIRS) devices such as Labspec4® can be considered as alternative techniques to human subjective grading, but measurements must be conducted on deboned hams. The NitFom™ (Frontmatec) is a NIR based measuring device dedicated to on-line measurements at high speed on hot or cold carcasses by invasive probing. The objective of the study was to evaluate the accuracy of PSE-like zone classification using NitFom™ on bone-in hams and to compare its prediction quality with the previously tested Labspec4® on deboned hams.
