Fatty acid profiles and health lipid indices in the breast muscles of local Polish goose varieties

Abstract

The aim of this study was to evaluate the fatty acid profile and health lipid indices of meat from 3 Polish local goose varieties (Romanian–RO, Pomeranian–PO, and Subcarpathian–SB) and the commercial cross White Kołuda goose (W31). Birds were fed ad libitum with the same complete feeds until 17 wk of age. The geese (n = 72) with body weight close to the arithmetic mean in particular flock were fasted for 12 h and slaughtered in an experimental slaughterhouse (18 females in each flock). Carcasses were stored at 2 to 4°C for 24 h. The breast muscles ( m. pectoralis major ) were cut out from the left side of carcass, separately vacuum-packed, and stored at −80°C until analysis. Fatty acid profile of meat was determined by gas chromatography and health lipid indices were calculated. The W31 muscles had a higher percentage of C 18:0 and a lower of C 16:0 than those of RO, PO, and SB geese. The W31 muscles were characterized by a significantly higher proportion of monounsaturated fatty acids (46.5%) than remaining ones (43.28%–PO, 43.38%–SB, and 44.24%–RO). The lowest proportion of polyunsaturated fatty acids was established for W31 muscles (22.05%). The breast muscles of RO, SB, and PO had more favorable polyunsaturated n-6 and n-3 fatty acid (PUFA)/ saturated fatty acid ( SFA ) ratio (0.85, 0.82, 0.83, respectively) than W31 geese (0.72). The current findings showed that UFA/SFA, PUFA/SFA, and PUFA n-6 / n-3 ratios in RO and SB muscles were within the optimum values for human diets. No significant differences were observed in the atherogenic, thrombogenic, and hypocholesterolemic/hypercholesterolemic indices between the analyzed muscles. Commercial W31 geese breast muscles showed a lower value (43.90%) of peroxidizability index ( PI ) compared to SB (52.88%), PO (53.93%), and RO (53.47%). However, the higher values of the PUFA/SFA and PI in the meat of SB, PO, and RO birds may indicate a higher prohealth value of their meat.

Effects of Supplementation of Microalgae (Aurantiochytrium sp.) to Laying Hen Diets on Fatty Acid Content, Health Lipid Indices, Oxidative Stability, and Quality Attributes of Meat

“…From the perspectives of human health, healthy animal products can be characterized by low AI and TI and a high h/H ratio. Generally, the desired AI and TI recommended for human consumption are less than 0.5 and 1.0, respectively [29]. In this study, the breast meat showed AI and TI of 0.42-0.43 and 0.60-0.82, and the thigh meat showed AI and TI of 0.42-0.44 and 0.62-0.80 with MA supplementation, which were within the recommended ranges.…”

“…AI and TI are vital parameters indicating the potential for stimulating platelet aggregation, and the h/H ratio is associated with cholesterol metabolism [29]. From the perspectives of human health, healthy animal products can be characterized by low AI and TI and a high h/H ratio.…”

“…Fats with the PUFAs/SFAs ratio of greater than 0.45 are recommended for human consumption to minimize the risk of CVD and other chronic diseases [ 12 ]. In the present study, PUFAs/SFAs ratios ranged from 0.89 (black shrimp waste) to 1.70 (red shrimp waste) ( Table 5 ), which falls within the recommendations.…”

“…The fatty acid profile was used to determine several nutritional parameters of lipids, including ratios of PUFAs/saturated fatty acids (SFAs), PUFAs/monounsaturated fatty acids (MUFAs), and hypocholesterolemic (h)/hypercholesterolemic fatty acids [ 11 , 12 ]. Furthermore, the atherogenic index (AI) [ 11 ], and thrombogenic index (TI) [ 13 ] were calculated as the following equations: …”

“…Atherogenic index and TI are vital parameters indicating the potential for stimulating platelet aggregation, which defined as the relationships between proatherogenic FA and antiatherogenic FA and relationships between prothrombogenetic FA and antithrombogenetic FA, respectively ( Wołoszyn et al., 2020 ). From the perspectives of human health, the AI and TI recommended for human consumption are less than 0.5 and 1.0, respectively ( Wołoszyn et al., 2020 ). In this study, the yolks showed AI and TI of 0.37–0.41 and 0.69–0.73, which were within the recommended ranges.…”
