2009), which indicated that with the increasing of effective tumbling time from 4 h to 10 h, the combination of tumbling (involving meat rotating, falling and contacting with metal walls and paddles in a tumbler drum) and marinade (containing salt and polyphosphate) facilitated loosening the muscle structure, disrupting cell membranes, destroying the connection between the myofibril and collagen, promoting marinade permeation and distribution in the meat and improving the solubilization and extraction of SSP, thus reducing the MD.
2], which were involved in muscle energy metabolism, glycolytic pathway in adenosine triphosphate generation, and organization of myofibril, respectively) were downregulated with the increase of storage time.
4) The calcium-sensitizing effect of pimobendan is mediated by an increase of the affinity of troponin C calcium-binding sites to calcium, which in turn, lowers the threshold for calcium-dependent myofibril contraction.
