Maturity And Marbling

The slight level had significantly more protein.

Maturity and marbling.

The relationship of physiological maturity and marbling judged according to korean grading system to meat quality traits of hanwoo beef females. For the prime grade the minimum degree of marbling required is a minimum slightly abundant amount for carcasses throughout the range of maturity permitted in the bullock class. A trend toward larger fiber diameters was noted for the muscle fibers from the more mature carcasses. Marbling was significantly p 0 01 correlated with quality grade crude fat content cook and drip.

Marbling was significantly p 0 01 correlated with quality grade crude fat content cook and drip losses and warner bratzler shear force. The maturity level was also significantly p 0 01 correlated with quality grade fat colour texture score number of calves produced and milk teeth meat redness and yellowness fat yellowness and warner bratzler shear force. Relationship between marbling maturity and carcass quality grade assumes that firmness of lean is comparably developed with the degree of marbling and that the carcass is not a dark cutter maturity increases from left to right a through e. Beef carcass quality grading is based on 1 degree of marbling and 2 degree of maturity.

Graders evaluate the amount and distribution of marbling in the ribeye muscle at the cut surface after the carcass has been ribbed between the 12th and 13th ribs. The moderate marbling level had significantly p 01 more fat and less moisture than the slight level. Marbling intramuscular fat is the intermingling or dispersion of fat within the lean. Graders evaluate the amount and distribution of.

Marbling marbling intramuscular fat is the intermingling or dispersion of fat within the lean. The a maturity protein percents were significantly lower than those of the b c and d groups. Least square means were generated using the lsmeans option and separated when significant p 0 05 using the pdiff option. Tenderness flavour and overall acceptability scores for the older maturity group were lower than for younger and intermediate groups.

The ribeye muscle is moderately firm and in carcasses having the maximum maturity for this class the ribeye is light red in color. The interaction of maturity and marbling was used as a covariate in the models of carcass traits and meat quality traits to decrease the residual error of the model.
