The aim of the study was to investigate changes of the fatty acid profile in the intramuscular and subcutaneous fat as well as odor sensory evaluation of goose packaged under different conditions of modified atmosphere (vacuum and high-oxygen modified atmosphere of 80% O2 and 20% CO2 composition) and stored under refrigeration (4°C) for 11 D. Packaging in a high-oxygen modified atmosphere had a negative impact on goose meat quality due to the reduction of polyunsaturated fatty acids (PUFA), PUFA/saturated fatty acids (SFA) and the increase of SFA, which means a substantial loss of its nutritional value. Goose meat can be stored for 11 D without changes in the fatty acid profile, provided that a vacuum is used that limits oxygen exposure. At the end of storage, a better sensory evaluation of the odor intensity in the vacuum-packed samples was also observed in comparison to high oxygen modified atmosphere. Vacuum packaging turned out to be a better method for preserving fatty acid profile and the odor of goose meat during 11 D of storage.
