Two simple, accurate, rapid and economical methods for determining variations in drip loss of lean, prepackaged, post-rigor porcine musculature during storage have been developed. Laboratory grade filter paper having a 45 mm diameter was placed on the cut surface of the muscle (after 10-15 minutes' exposure) and scored for wetness (0 to 5) within 3 s or(More)
A total of 265 pork carcasses representing a broad variation in quality was used to examine the relationship between colour (L-value) and water-holding capacity (WHC) in the longissimus thoracis et lumborum. Thirty-four samples appeared to possess 'normal' reddish pink colour (L-value 52·0-58·0) but had 'unacceptable' WHC (>5·0% drip loss). Conversely, 25(More)
Water-holding capacity (WHC) of muscle is important because it affects both qualitative and quantitative aspects of meat and meat products. For assessment of WHC under field and laboratory conditions, there are several methods available, but they have not been compared in a single experiment to determine accuracy and repeatibility. The Longissimus dorsi(More)
A total of 1764 male calves of the Meuse-Rhine-Yssel (MRY) and Friesian-Holstein (FH) breeds were slaughtered at two commercial slaughterhouses to investigate the variation in pH, temperature, and colour of Dutch veal carcasses processed without electrical stimulation and with a moderate chilling regimen (average temperature of the longissimus lumborum(More)
An experiment with 1969 pigs, belonging to Yorkshire sire lines, was set up in cooperation with seven Dutch breeding organizations. The pigs, which were claimed to be halothane negative, were slaughtered in weekly batches. Light reflectance was determined with the Hennessy Grading Probe (HGP) and Fibre Optic Probe (FOP), in addition to pH(1) and rigor(More)
Variations in pork quality reflect value differentials. However, only when they can be easily, accurately, rapidly and cost-effectively detected, can swine producers expect to eliminate poor quality from their herds through genetic selection, and can the industry be expected to take the necessary environmental precautions to prevent poor quality.
