1)Freezing system: NF (natural conventional freezing), IQF (individual quick freezing), and CF (cryogenic freezing)
2)Thawing system: NCT (natural convection thawing) and RT (running water thawing)
3)Control, raw beef
A-CMeans with different superscripts within same column are significantly different (p<0.05).
