A total of 72 Holstein-Friesian males from 11 sire groups were reared from birth on a concentrate ration. At 136 kg, one-half of the calves were castrated (Burdizzo) and at 340 kg, one-half of the bulls and steers were implanted with hormones (200 mg progesterone plus 20 mg estradiol-17-β-benzoate). Following slaughter at 475 kg, the 9th–11th rib sections were removed from the left sides of the carcass and frozen. Later, the four treatment and 11 sire groups were compared by taste panel evaluation of these rib roasts. No significant differences in quality factors (tenderness, juiciness, and flavor) due to pre-slaughter hormone treatment were evident in rib roasts from either bulls or steers. Hormone treatment significantly decreased (P < 0.05) fat deposition in steers and tended to increase fat levels in bulls. Rib roasts from bulls were significantly less desirable than roasts from steers in both treatment groups, for all quality factors. Significant sire effects for all taste panel evaluations were also noted.

Hams were sampled from 144 pigs, 36 each of barrows, gilts, boars, and ridglings, which ranged from 87 to 93 kg live weight at the time of slaughter. Ham steaks, prepared and cooked by a standardized procedure, were evaluated for cooking aroma, tenderness, juiciness, texture, flavor, and overall preference by a taste panel of six judges.For tenderness and texture, the samples from boars ranked highest followed by gilts, barrows, and ridglings. All sex differences were statistically significant [Formula: see text] for these two characteristics. Ranking for overall score and overall preference by judges was in this same order.Samples from barrows and ridglings scored higher for cooking aroma than the samples from boars and gilts [Formula: see text], although only three boars and one gilt were unanimously judged objectionable. However, aroma was lowly correlated with flavor (r = 0.28) and samples scoring low for aroma were often quite satisfactory for flavor.Samples from boars, gilts, and barrows received scores for flavor that were equivalent and exceeded the score for ridglings by 0.35 units [Formula: see text].It was observed that objectionable odors noted in the cooking of pig meat may, in the absence of knowledge of the sex involved, be incorrectly attributed to the entire male or to the ridgling pig.

Sodium tripolyphosphate treatment before packaging and freezing of fillets of trap-caught cod (Gadus morhua L.) in-rigor was compared with treatment in plain water.The once-frozen treated fillets, evaluated by an analytical taste panel after frozen storage at −12°F (−24.5 °C) for periods up to 27 weeks, had significantly better texture characteristics than did the untreated control fillets.Thaw-drip was significantly smaller in treated samples but this effect was less pronounced after extended frozen storage.Lipid hydrolysis proceeded at the same rate in both treated and untreated fillets.There was no significant difference between the electrophoretic patterns of the proteins found in the treated and untreated samples. In both cases the muscle albumins constituted the major portion of the proteins in the drip.Results indicate that polyphosphate-treated fillets prepared from trap cod could have greater market acceptance than untreated fillets. The producer would benefit from improved quality of product and from increased yield.
