OCAMPO IBANEZ, Iván Darío; BERMUDEZ M, Fanhor  e  DIAZ, Héctor. Effect of storage time, muscle type, and animal genotype on drip loss in raw pork. Acta Agron. [online]. 2009, vol.58, n.3, pp.180-188. ISSN 0120-2812.

In one factorial design arranged in Subdivided Plots was analyzed the effect of the storage time (24, 48 and 72 hours at 6° C), the muscle type (Longissimus dorsi, Triceps brachii, Biceps femoris) and the genotype of the animal (3 pure breed: Yorkshire, Landrace, Duroc; 2 genotypes: F1 like a hybrid between Yorkshire and Landrace (YL), and one cross between the F1 and Duroc (F1D)) on the drip loss in raw pork. The samples were taken after 24 hours postmortem and were stored during 72 hours. The bigger percentage of drip loss was presented for pork obtained from the Biceps femori muscle taken from F1 animals. The bigger percentage of loss was during the first 24 storage hours. The results indicated that there was significant highly statistics differences (p<0.01) for the individual effects: genotype, muscle type and storage time on the percentage (%) of the drip loss.
