Effects of fibre type and structure of longissimus lumborum (Ll), biceps femoris (Bf) and semimembranosus (Sm) deer muscles salting with different Nacl addition on proteolysis index and texture of dry-cured meats

摘要

The aim of the present study was to describe the effect of fibre type and structure as well as NaCl level on the proteolysis index and texture parameters observed in dry-cured meats produced from individual deer muscles. The biceps femoris, semimembranosus and longissimus lumborum muscles were cut from deer main elements, shaped into blocks by trimming off the edges, cured by adding 4,6 and 8% of salt (w/w) and dried in a ripening chamber for 29 days. The results indicated that deer dry-cured muscles with higher percentage of red fibres (type Ⅰ) showed higher texture parameters, proteolysis index as well as lower moisture losses than muscles with higher amount of white fibres (type ⅡB). Dry-cured deer muscles with lower NaCl content showed higher values of proteolysis index and lower hardness, cohesiveness, springiness, and chewiness, as well as lower changes in structure elements.
