Rapid prediction of beef quality remains a challenge for meat processors. This study evaluated the potential of Raman spectroscopy followed by chemometrics for prediction of Warner-Bratzler shear force (WBSF), intramuscular fat (IMF), ultimate pH, drip-loss and cook-loss. PLS regression models were developed based on spectra recorded on frozen-thawed day 2 longissimus thoracis et lumborum muscle and validated using test sets randomly selected 3 times. With the exception of ultimate pH, models presented notable performance in calibration (R2 ranging from 0.5 to 0.9; low RMSEC) and, despite variability in the results, promising predictive ability: WBSF (RMSEP ranging from 4.6 to 9 …

The aim of this study was to compare the quality of meat of the young Limousin bulls slaughtered at the age of 6, 9 and 12 months, with particular regard to the residual glycogen content in the meat and the value of the glycolytic potential. The study was conducted on bovine longissimus lumborum muscle. The residual glycogen content, glycolytic potential value (96 h post-mortem), pH value (45 min, 24 h, 48 h and 96 h post-mortem), IMP/ATP index (45 min post-mortem), colour parameters (L*, a* and b*), natural and cooking losses, free water content, the chemical composition, sensory parameters (aroma, …
