Abstract

The tenderness of 160 samples of m. longissimus thoracis et lumborum (LL) from 40 sheep carcasses was measured at two laboratories, 80 samples per laboratory, with two ageing times (0 and 5 days). The samples were all cooked from frozen and then measured on the same type of machine, a Lloyd Texture analyser with a WarnerBratzler-type shearing blade attached to give a shear force value for each sample. Shear force results were natural log-transformed and the analysis showed that there was a significant (P 0.05) effect of ageing on cooking loss, but there was a significant (P < 0.05) difference between the laboratories. On equivalent samples, Laboratory B produced lower cooking loss results (..
