Special Issue Information

Dear Colleagues,

Current data on the production and consumption of pork in the world, in addition to forecasts for the next decade, indicate its significant share in the global meat industry. Many factors along the production chain, from farm to fork, can affect the quality of pork meat and pork products. Stakeholders’ priorities vary, i.e., across farmers, slaughterhouse owners or factory owners, consumers, and public health experts. A comprehensive approach based on multi-criteria research can help find trade-offs between stakeholders and obtain a satisfactory food product. In view of the above, future research is needed to demonstrate the influence of potential factors on the quality characteristics of pork meat and pork products, including their safety for consumers.

Considering all this together, the purpose of this Special Issue is to present the current knowledge on the production and broadly understood quality of pork meat and pork products, as well as to address potential research gaps.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. On-farm factors affecting pork carcass and meat quality attributes;
  2. Factors affecting pork carcass and meat quality attributes;
  3. Pork meat production technology;
  4. Microbiological quality of pork and pork products;
  5. Assessment of safety risks associated with pork meat and pork products;
  6. Nutritional value of pork meat and pork products;
  7. Pork meat as a functional food.

Variations in postmortem metabolism in muscle impact pork quality development. Curiously, some genetic lines are more refractile to adverse pork quality development than others and may regulate energy metabolism differently. The aim of this study was to challenge pork carcasses from different genetic populations with electrical stimulation (ES) to determine how postmortem metabolism varies with genetic line and explore control points that reside in glycolysis in dying muscle. Three genetic populations (GP) were subjected to ES (100 V or 200 V, 13 pulses, 2 s on/2 s off) at 15- or 25-min post-exsanguination, or no stimulation (NS). Genetic population affected relative muscle relative abundance of different myosin heavy chains, glycogen, G6P, and lactate concentrations. Genetic lines responded similarly to ES, but a comparison of ES treatment groups revealed a trend for an interaction between voltage, time of ES, and time postmortem. Higher voltage accelerated pH decline at 20 min up to 60 min postmortem. Trends in color and firmness scores and L* values were consistent with pH and metabolite data. These data show that genetic populations respond differently to postmortem perturbation by altering glycolytic flux and suggest differences in postmortem glycolysis may be partially responsible for differences in meat quality between genetic populations, though not entirely.

The nutritional quality of meat and the health-promoting properties of intramuscular fat from randomly selected rearing pigs of the native Puławska breed (PUL, n = 15) and its crossbreeds with the Polish Large White breed (PLW × PUL, n = 16) and the DanBred hybrids (DAN, n = 17) were compared. The typical commercial fattening period was carried out up to 80 days of age. The initial body weight of PUL weaners was 30.55 kg (±3.98 kg), that of PLW × PUL weaners was 30.00 kg (±4.29 kg) and that of DAN weaners was 30.70 kg (±3.40 kg). The protein content and energy value of the complete feeds (Grower and Finisher) were 165 and 155 g/kg, and 12 and 11.8 MJ/kg, respectively. The research material consisted of samples of Longissimus lumborum and Semimembranosus. The chemical analyses included the determination of proximate composition, fatty acid content and amino acid concentration. The lowest fat content was found in the meat of the Puławska pigs, while the highest was found in the DanBred fattening pigs. The highest content of SFAs and MUFAs was found in the meat of DanBred hybrids, while it was significantly lower in Puławska pigs. The genetic group did not affect the content of PUFAs, including n-3 and n-6. Significantly lower and more favourable atherogenic and thrombogenic indices were found for the intramuscular fat of Puławska pigs. The very limited effect of the genetic group on amino acid content was observed, except for that of serine, histidine and lysine. In general, the meat of pigs of the Puławska breed showed the highest nutritional value and the most favourable health-promoting properties. Full article
