Halothane genotype and pork quality. 3. Comminuted meat products derived from the three halothane genotypes

Fisher P. ; Mellett F.D. ; Hoffman L.C. (2000)


The effect of the halothane gene on cured meat products was investigated using the meat from 60 Landrace×Large White pigs of known halothane genotype (NN=25, Nn=19, nn=16). Results for the two types of fresh sausage manufactured (with and without rusk) indicated that the NN pigs (15.7%) had lower total moisture losses (P<0.05) compared to the nn pigs (18.9%), with Nn being intermediate (17.4%) for the sausage without rusk. Where rusk was added, there were no significant differences between genotypes for moisture losses (NN=12.6%, Nn=13. 0%, nn=14.2%). Taste panel evaluations of the fresh sausages made without rusk indicated no genotypic influence for juiciness, however the sausage made with the rusk was judged the juiciest for the nn genotype, with Nn being intermediate and NN the least juiciest. The smoking and cooking losses during manufacturing of the emulsion product (vienna) indicated that the nn genotype (12.5%) had significantly (P<0.05) higher total losses than the Nn genotype (11. 3%), with NN being intermediate (12.4%). © 1999 Elsevier Science Ltd.
