    Notes: SUMMARY: Steaks from 24 bulls 20 months old, 89 bulls 14 months old and 109 steers 20 months old were used to relate thickness of epimysial tissue to the amount of intra-muscular connective tissue, and to correlate these factors with Warner-Bratzler shear values in muscles cooked to 140 or 160°F. The thickest portion of the LD epimysium was greater in lighter weight bulls than it was in heavier steers. Epimysial extension and thickness varied according to muscle location but at the same location it was not significantly different in steaks from tough versus tender steers. Differences in hydroxyproline content and connective tissue of steers and young bulls were small but older bulls had slightly greater amounts of both. The LD epimysium was tougher in older bulls than in younger bulls.Shear values of epimysial tissue varied considerably within animals of the same age, especially when roasted to 140°F. Most connective tissue differences due to line of cattle were small. Correlations within groups of cattle between thickness of epimysial tissues of different muscles or between epimysial thickness and intramuscular connective tissues were low. With few exceptions neither hydroxyproline, epimysial thickness nor connective tissue scores were significantly related to shear force of muscle or shear force of epimysial tissue itself. Correlations between shear force of the LD and BF muscles were not significant (P 〈 0.05) in animals of the same age. There was a tenderness interaction between age of animal and type of muscle which suggested that collagen gelatinization occurred at a faster rate in the LD than in the BF as age increased.

    INFLUENCE OF YIELD ON CALCIUM CONTENT OF MECHANICALLY DEBONED LAMB AND MUTTON (1974)

    Notes: Mutton carcasses and lamb carcass cuts were mechanically deboned at different settings to give variable yields of mechanically deboned meat. Higher yields of mechanically deboned meat were related to higher calcium and fat percentages. Lamb breasts had the lowest bone percentage of any of the cuts and the mechanically deboned meat from breasts had the lowest calcium content when compared to deboned meat from other lamb cuts or mutton carcasses. Necks had the highest bone percentage and the highest calcium content in the mechanically deboned meat. Data are presented which show that mechanically deboned meat is not homogenous as it is extruded from the cylinder. Palatability of bologna made with mechanically deboned meat increased as the size of cylinder holes through which the meat was extruded decreased.

    Effect of Cooking Method on the Texture of Epimysial Tissue and Rancidity in Beef Roasts (1986)

    Notes: Twelve top round roasts from two Utility-grade cows were randomized and cooked by microwave, convection or conventional methods after epimysial tissue had been inserted into each roast. The freshly cooked and stored roasts were evaluated for rancidity using three TBA methods, and textural determinations were made on epimysial tissue. TBA numbers increased from day 0 through day 11. Shear values for epimysial tissue from 8-year old animals cooked by microwave tended to be lower than those for tissues cooked by convection or conventional methods, but no differences in cooking method were observed for tissue from l-year old animals.

    Lipid Characterization of Longissimus and Biceps Femoris Muscles from Beef Animals Exsanguinated at Various Times after Stunning (1982)

    Notes: Lipid characteristics of bovine longissimus and biceps femoris muscle from 30 heifer carcasses which were exsanguinated 0 (control), 3 or 6 min after stunning were studied. Blood loss was greater when control animals were compared to animals stunned 3 or 6 min prior to exsanguination. However, total lipid, lipid phosphorus, cholesterol values and TBA numbers were similar among treatments. As time between stunning and exsanguination increased, monounsaturated and polyunsaturated fatty acids tended to increase. Delaying time between stunning and exsanguination had little influence on lipid characteristics of muscle even though large differences between lipid characteristics of muscle and blood exist.

    Notes: Marrow from cervical, lumbar and femur bones of 5 steers and 5 cows fed only on native range (grass fed) and 5 steers and 5 cows fed a finishing ration (grain fed) was analyzed for cholesterol content. The cholesterol content of the marrow was significantly different when diet or anatomical locations were compared. Bovine marrow from grass-fed animals averaged 119.6 mg/100g and marrow from grain-fed animals averaged 150.6 mg/100g marrow. The cholesterol content of marrow from the cervical, lumbar, and femur was 190.1, 124.1, and 91.0 mg/100g marrow, respectively. Mechanically deboned meat (MDM) and beef lean had a mean cholesterol content of 153.3 and 50.9 mg/100g tissue. Spinal cord material in MDM can account for the increased concentration of cholesterol in some MDM samples over the values for lean and marrow.

    PROTEIN QUALITY OF MECHANICALLY PROCESSED (SPECIES) PRODUCT AND BONE RESIDUE (1979)

    Notes: Six samples of mechanically processed (species) product (MPP) from a Beehive deboner equipped with 0.46 mm holes in the cylinder, one sample of beef semimembranosus muscle and three samples of bone residue were analyzed. Protein efficiency ratios (PER) for MPP ranged from 1.44–2.90 compared to 2.91 for beef semimembranosus muscle. None of the bone residue samples supported rat growth giving a PER of ≤O. Regression equations to predict the PER of MPP were developed using the data obtained on the six MPP samples and the three bone residue samples described in this paper plus PER and amino acid data obtained on nine other samples of MPP. The regression equations were then tested using 24 different lots of MPP. Multiple regression equations using leucine and proline or hydroxyproline and isoleucine as independent variables were suitable for use in categorizing MPP on the basis of protein value. An alternative method of controlling protein quality in MPP by limiting the hydroxyproline content was suggested.

    Notes: A method for the determination of total porphyrins in beef biceps femoris and semitendinosus muscles, in beef red bone marrow and in lamb biceps femoris and semitendinosus muscles is reported. Tissues of decreasing levels of porphyrins were: red marrow, beef biceps femoris, beef semitendinosus, lamb biceps femoris, lamb semitendinosus. Protoporphyrin was the major, if not only, porphyrin present in the muscle and marrow samples.

    Notes: BONE PARTICLES from five lots of mechanically deboned meat (MDM) from beef neck bones were characterized with regard to size and stability. The largest bone particle diameters were close to the theoretical limit of 460μ but average bone particle diameters ranged from 76.6μ (S.D. = 37.4) to 111.7μ (S.D. = 49.1). Bone particles were stable in MDM but they were readily solubilized in 0.018 – 0.15M HCl.

    Notes: Mechanically deboned meat (MDM) from flat bones of mature cows and bulls from three regions of the country and pork MDM from two regions were evaluated. The samples were collected from regions where high levels of fluoride occurring in the water and vegetation have been reported. Higher magnesium, iron and fluoride contents were found in beef MDM from the West and Midwest regions when compared to the Southern region. Higher iron and fluoride contents were found in beef MDM compared to pork MDM. MDM had a higher iron content than regular muscle, which was attributable to increased amounts of iron in bone marrow. Iron was suggested as a method for determination of red bone marrow percentage in MDM.

    Notes: Four groups of Good and Choice grade carcasses were hand boned. Flat bones from the right sides were mechanically deboned using a Beehive machine with 0.46 mm holes in the cylinder and designated mechanically deboned meat (MDM). Flat bones from the left sides were hand-cleaned of all visible muscle and fat and then run through the mechanical deboner and designated mechanically separated tissue (MST). No significant differences in moisture, fat or protein between tissue from the right and left sides were present, but MDM had less ash than did MST. Higher ash content in the MST was paralleled by higher values (P 〈 0.05) for iron, calcium, magnesium, collagen and pH. Greater amounts of isoleucine (P 〈 0.05) were present in MDM than in MST. Bologna was formulated to contain 30% MDM or 30% MST. No differences in processing quality of the bolognas were noted. Independent triangle tests for flavor and grittiness showed that panel members could detect differences (P 〈 0.01) in bologna containing MDM or MST when compared to control bologna.
