The influence of muscle, ageing and thermal treatment method on the quality of cooked beef

The study was undertaken to investigate the effect of muscle, thermal treatment, and ageing on the beef quality. The longissimus lumborum (LL) and semimembranosus (SM) muscles were taken from Holstein-Friesian young bull carcasses then subjected to steam-cooking and sous-vide after 9 and 14-d wet ageing. It was shown that characteristics of cooked beef were the most significantly affected by thermal treatment method. Using sous-vide provided beef with lower shear force and cooking loss values, darker, and more red colour and more beneficial sensory quality. LL and SM muscles showed a similar quality when subjected to the same thermal treatment method after the same ageing time. It is possible to obtain juicy and tender beef from Holstein-Friesian bulls after 9-d ageing and sous-vide treatment.

Automated summary

The study revealed that thermal treatment methods significantly affect the characteristics of cooked beef, with sous-vide resulting in beef that is more tender, juicy, darker, and redder, with better sensory quality. LL and SM muscles showed similar quality after the same thermal treatment following the same ageing time.
