Abstract The effects of postmortem aging time, chopping time and salt addition on the texture, yield and sensory quality of beef meatballs made from outside flat were studied by uniform design. The results showed that all three factors considered had significant effects (P < 0.05) on the texture, yield and sensory score. Springiness decreased at first and then increased with postmortem aging time. Resilience rose gradually with increasing postmortem aging time or salt addition, whereas it increased at first and then fell with increasing chopping time. Hardness decreased initially and then increased with increasing postmortem aging time, and it declined gradually with increasing chopping time but rose gradually with increasing salt addition. The yield and sensory score declined with postmortem aging time, especially at low levels of salt addition. Hence we concluded that the quality of beef meatballs could be improved by shortening the postmortem aging time.
