Muscle pH was measured 24 h post mo

Muscle pH was measured 24 h post mortem (pHu)
in LongissimusDorsis (LD) muscle with a pHmeter
(Testo 230, BA, Argentina) according to the
methodology suggested by Garrido et al. (2005)
(4). All carcasses (20 per batch) were ordered
according to pHu values and 3 groups were
formed: high, medium and low pH. Two carcasses
were randomly selected from each group. In this
way, 60 carcasses were selected, 6 from each
batch. Instrumental colour (L*, a* and b*) was
measured according to the methodology suggested
by Albertí et al. (2005) (5) using a Minolta CR-400
colorimeter (Konica Minolta Sensing, Inc., Bergen,
NJ, USA) with D65 illuminantand an 8-mm
aperture. Each muscle was allowed to bloom for 30
min at 2 ± 1 °C before colour measurement. Colour
variation (ΔE) was calculated as follows

Otot pH adalah diukur 24 h visum (pHu)otot LongissimusDorsis (LD) dengan pHmeter(230 Testo, BA, Argentina) menurutmetodologi yang diusulkan oleh Garrido et al. (2005)(4). semua karkas (20 per batch) diperintahkanMenurut pHu nilai-nilai dan 3 kelompok yangdibentuk: pH tinggi, menengah dan rendah. Dua karkassecara acak dipilih dari setiap kelompok. Dalam hal iniWay, 60 karkas dipilih, 6 dari masing-masingbatch. Instrumental warna (L *, * dan b *) adalahdiukur sesuai dengan metodologi yang disarankanoleh Albertí et al. (2005) (5) menggunakan Minolta CR-400Colorimeter (Konica Minolta Sensing, Inc, Bergen,NJ, Amerika Serikat) dengan D65 illuminantand 8-mmaperture. Setiap otot diperbolehkan untuk mekar selama 30min 2 ± 1 ° C sebelum pengukuran warna. Warnavariasi (ΔE) dihitung sebagai berikut
