Muscle longissimus

For example, the muscle Longissimus dorsi is a muscle of pork loin (cutlet) and the muscle Rectus femoris is the main muscle of pork leg (oyster piece). 

Lakritz et al. (32) reported that radiation doses of less than 10 kGy (at 0 to 4 C) produced minimal changes in the micro structure of bovine longissimus dorsi muscle. At doses of 30 kGy or higher, myofibril fragmentation and decreased tensile strength were noted. Lakritz and Maerker (33) reported reductions of 8% and 42% in the activities of lysosomal enzymes and acid phosphatase of irradiated (10 kGy) bovine longissimus dorsi muscle tissue.

The distribution of CLA over cell organelles is only rarely described in the literature. In 2002 Demaree et al. (41) examined the interaction between CLA and dietary fat type on the enrichment of subcellular fractions, the desaturase index and adiposity in pigs. Early weaned piglets were fed for 35 days on diets supplemented with 15 g beef tallow or corn oil/ 100 g diet, or 12 g tallow or corn oil plus 3 g CLA/100 g. It turned out that microsomes accumulated <50% the concentration of rl0,cl2-, and c9,rll-CLA as membrane fractions (containing plasma membranes, nuclei, and mitochondria) and nonmembrane fractions (containing nonpolar lipids) of adipose tissue and longissimus muscle. There was no evidence of preferential...
