Abstract:

Rabbit longissimus dorsi muscle was examined for the effect of frozen temperature on its pH, color, tenderness, waterholding
capacity, TVB-N, TBARS value, protein solubility, gel G′ value and microstructure. The results showed that during storage
at −18 ℃, rabbit meat pH decreased faster than at −40 and −80 ℃. Higher storage temperature could lead to worse color and
tenderness of rabbit meat, greater thawing loss and cooking loss, higher TVB-N and TBARS values, lower protein solubility and
gel G’ value, and more severe microstructure changes. Fast changes in the investigated parameters were observed after 60 days of
storage at different temperatures, demonstrating the appropriate frozen storage time should not exceed 60 d.

Key words: rabbit, frozen, eating quality, processing characteristics, microstructure
