Abstract/OtherAbstract:
Four groups of carcasses of eighty grain fed low stressed steers (~12months old, 240kg carcass weight) received no stimulation or had low voltage stimulation for 15, 45 and 90s. M. longissimus was aged for 2 and 14days at 2°C. Shear force, sarcomere length, water holding capacity, purge, muscle fibre detachment, sarcomere breaks and colour shelf life over 7days was measured. Both 45s and 90s stimulated samples completed rigor above 35°C and 15s stimulated and non-stimulated samples below 35°C. The greatest muscle fibre detachment occurred for 15s stimulated samples which were the most tender at all times with non-stimulated samples toughest at 2days of ageing and all samples being tender at 14days of ageing. The 45 and 90s stimulated samples consistently exhibited a brighter red colour at 2days of ageing with no differences in colour intensity for the samples aged 14days.
