NTA, natural thawing in the air; DVT, domestically designed-vacuum tumbler; IVT, imported vacuum tumbler.
TAB, total aerobic bacteria.
TBARS, thiobarbituric acid reactive substance; MDA, malondialdehyde.
VBN, volatile basic nitrogen.
All values are mean±SD (n=3) and different superscripts (a-c) within the same column indicate significant differences (p<0.05).
ND, not detected.
