Pork forelegs were used for manufacturing fresh sausages, treated with different natural antioxidants (rosemary, ascorbic acid and black pepper), packaged in 80% O(2)+20% CO(2) atmosphere and displayed at 2±1°C under different lightings (darkness, standard fluorescent, low-UV colour-balanced lamp and standard fluorescent plus a UV-filter). Two packs for each treatment were opened every 4 days for subsequent analysis of colour CIE L(∗), a(∗), b(∗), TBARS, microbial psychrotrophic aerobes and sensory discolouration and off-odour. Lighting with standard fluorescent was highly deleterious for sausage display life, which fell from 12 to 8 days due mainly to early discolouration.

Instrumental colour and texture, pH, non-protein nitrogen, total volatile basic nitrogen, acidity, lipid oxidation, sensory profile and consumer acceptability and purchase satisfaction were measured throughout storage. The overall quality of vacuum-packaged dry-cured ham cuts showed limited changes.

Univariate (Kolmogorov-Smirnov test and t-test) and multivariate (canonical correlation and principal component analysis) statistical procedures have been used to explain the agreement and disagreement between panels evaluating similar and dissimilar sensory attributes quantified with a 9-points structure scale. The results pointed out that there were basic agreements between panels, although some disagreements were detected in mould, acorn and crust attributes.

Sausages (240) were packaged in a 80% O2 + 20% CO2 gas mixture and analyzed for CIE a, metmyoglobin, TBARS, psychrotrophic aerobes, and sensory discoloration and off-odor throughout 20 days of storage at 2 +/- 1 degrees C. The mixture of rosemary + ascorbic acid + sodium lactate + red beet root extract extended the shelf life of fresh pork sausages from 8 to 16 days.

Sixteen vacuum-packaged boneless dry-cured hams and sixteen vacuum-packaged dry-cured ham cuts were stored in darkness under refrigeration (4±2°C; 8 months) or freezing (-18±1°C; 24 months), respectively. Instrumental colour and texture, physico-chemical and biochemical parameters, sensory profile and consumer acceptability and purchase satisfaction were measured throughout storage.

Carcass leanness and fat parameters were measured at the last rib and at the space between the 3rd and 4th last ribs counting from the last one. Weights, pH, electrical conductivity, colour and intramuscular fat were also measured.

Results demonstrated that ham acceptability showed no significant differences (p>0.05) from 12 to 22 months, while it decreased significantly (p<0.
