HISTOLOGICAL CHANGES IN BOVINE M. LONGISSIMUS DORSI FROZEN AT VARIOUS TEMPERATURES (-10, -2, -33 AND -78 C).

Author(s) : GAWWAD A. H., RAHELIC S.

Summary

IT WAS FOUND THAT: -263 K (-10 DEG C): LARGE GROUPS OF FIBRES ARE SEPARATED BY LARGE SPACES INDICATING INTERFIBRILLAR FORMATION OF LARGE CRYSTAL AGGLOMERATIONS. IN THE CENTER OF SOME FIBRES THERE WAS A HOLE. THE FIBRES ARE DAMAGED AT THE SURFACE AND SOMETIMES IN THE CORE ; -251 K (-22 DEG C): FIBRE GROUPS ARE SMALLER AND SEPARATED WITH SMALLER SPACES AND HOLES ARE FORMED IN SOME OF THEM. FIBRES ARE DAMAGED MORE BY SARCOLEME TEARING AS WELL AS FRAGMENTATION ; -240 K (-33 DEG C): THERE APPEARS INTERFIBRILLAR FORMATIONS OF SMALLER ICE CRYSTAL AGGLOMERATIONS ; FIBERS ARE LESS DAMAGED THAN IN THE PREVIOUSLY DESCRIBED SAMPLES ; -195 K (-78 DEG C): THE FIBRES LIE CLOSE TO EACH OTHER AND EVERY FIBRE HAS A HOLE INDICATING A GREATER FORMATION OF ICE CRYSTALS.
