Early post-mortem discrimination of water-holding capacity in pig longissimus muscle using new ultrasound method

摘要: Abstract Newly developed ultrasound equipment was tested for on-line determination of water-holding capacity (WHC) early post mortem (p.m.). The experiment based on measurements m. longissimus dorsi (LD) from 10 pigs, five which were treated to result in pork with high WHC and low WHC. Ultrasound carried out the carcass each pig every ten minutes 15 85 min p.m. at three locations LD. Low field nuclear magnetic resonance (NMR) performed excised samples simultaneously 24 h Drip loss measured by Honikel's bag method. demonstrated that classification meat possible, but only p.m., obtained posterior end NMR underlined there are structural differences influenced pre-slaughter treatment prior However, properties determine apparently not expressed sufficiently be registered applied pragmatic handheld before
