摘要:
The textural properties of beef over the temperature range -18 to +5 degrees C were measured using Warner Bratzler (WB) and tensile techniques. In addition, the effects of rapid radio frequency (RF) tempering and slower conventional air tempering on texture were compared. Temperature showed a significant effect (P < 0.05) on WB and tensile shear force, with higher values obtained at temperatures on or below -5 degrees C. Work to fracture Values showed two peaks at -15 and -3 degrees C. Sample thickness and muscle fibre direction were also important factors affecting shear force, with samples cut across fibres showing higher values. Tempering method showed no effect (P >= 0.05) oil the textural properties measured. In light of the rapid nature of RF tempering, these findings will be of interest to the meat industry.
