    Opis:
    The objective of this study was to assess how probiotic bacteria added to diets of 60 hybrid barrows (Landrace–Yorkshire x Duroc) affected the basic chemical composition of meat, the fatty acid profile of intramuscular fat (IMF), m. longissimus lumborum (LL) and lipid quality indices, because IMF cannot be removed before consumption and this inevitably has an impact on human health. After 78 days, the pigs were divided into the control group (CT, n=30) and the experimental group (BP, n=30), which until 97 days of rearing were supplied with BioPlus YC probiotic (Bacillus licheniformis DSM 5749 and Bacillus subtilis DSM 5750). After slaughter, 12 carcasses of similar weight (90 ± 5 kg) from each group were selected for testing. Supplementation with probiotic Bacillus did not affect the basic chemical composition of meat. It was established that BioPlus YC had a significant impact on capric – C10:0 (0.08 vs. 0.13), eicosatrienoic – C20:3 n-3 (1.76 vs. 2.14) and ΣPUFA n- 3 acids (1.88 vs. 2.41), causing a reduction in their percentage, which was thereby different than in the CT group. Among lipid quality indices, IMF LL of pigs from the BP group, the thrombogenicity index (TI) was characterized by a significantly (P≤0.01) higher value than in the CT group (1.08 vs. 0.99). These results suggest that further research is needed to study differences in compounds affecting the fatty acid profile of pork, and to confirm the association of the lipid profile with the use of BioPlus YC probiotic in pig fattening.

    Opis:
    This study investigated the effect of five in-house cooking methods (grilling, oven-cooking, frying, microwaving, and boiling) on lipid content and fatty acid composition in red mullet (Mullus barbatus). Moreover, the nutritional quality of the lipid fraction was evaluated by determining a number of lipid nutritional quality indices (LNQI). Moisture content of red mullet decreased after cooking, with the exception of boiled fish, while the lipid content significantly increased after microwave treatment and frying. After the latter, a ten-fold increase in lipid content was noted compared to fresh fish (from 2.1 to 21.1 g/100 g wet matter). All cooking methods caused significant changes in the fatty acid (FA) profile of M. barbatus. The content of saturated fatty acids (SFA) varied significantly between raw and cooked fish with the lowest values determined for fried sample. Monounsaturated fatty acid (MUFA) content increased after oven cooking and frying, while polyunsaturated fatty acid (PUFA) content showed an opposite trend. The eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) were the dominant fatty acids among n3 acids in all samples. EPA+DHA contribution in total FAs was significantly lower in the samples after oven cooking (19.6% total FAs) and frying (4.99% total FAs) than in the raw (25.5% of total FAs) fish. The n3/n6 ratio (range 1.25–3.65) decreased significantly after cooking; however, it remained above the recommended values for a healthy human nutrition (1:5). The PUFA/SFA ratio was between 0.69 in fried and 1.02 in boiled fish, both being greater than those recommended by the WHO/FAO [2003]. Atherogenicity index value decreased significantly after the cooking particularly in fried fish. The polyene index (PI), as a measure of PUFA damage, was in the range of 0.42–1.18. Although all cooking methods affected the FA profile, based on LNQI, it can be concluded that barbecue-grilling and boiling were the best cooking methods for healthy eating, due to their lowest effect on essential FAs.
