Guidelines for Handling and Storage of Emu Fat
Fat exists in two places on the emu, internally and externally. Very often there will be as much internal fat as external, sometimes more. It varies from bird to bird.
A well-fed emu will have a layer of fat over nearly the entire bird, lying like a second skin between the hide and the meat. It is just thinner in some areas than in others. The area along the leg from the drumstick down has probably the least amount of fat. The thickest amount will exist as a pad of fat on the rump. Neck fat will vary between 2 to 4 pounds depending on the bird.
There is a pad of fat below the vent and another one behind the breastbone. Fat can be pulled off the major organs but not the intestines, which will tear. The intestines surround a jellyfish shaped pad of fat. The fat is attached to the intestines between two layers of membrane, above and below the fat. Use kitchen shears to separate the fat from the intestines, taking care to avoid fecal contamination.
- Remove fat and hide from carcass, separately if possible. If not, remove fat from the hide as quickly as possible to retard bacteria growth. Do not leave the hide attached to the fat. There should be a minimum of blood, meat or feathers in the fat. It is not necessary to remove the quills (feather shaft).
- Wash the fat only if necessary to remove blood. Drain any excess water from the fat. You may use clean paper towels to absorb any water remaining on the surface of the fat. Water and blood promote the growth of harmful bacteria in the fat.
- Do not grind the fat. Grinding destroys tissue structures and results in the release of natural enzymes causing cellular material to breakdown. Grinding also homogenizes the fat with any remaining contaminants, such as blood, making it much more difficult to remove these contaminants from the resulting oil. Adverse chemical reactions within ground fat will make it difficult, or impossible, to produce an oil meeting the current AEA "Fully Refined" standards.
- Fat should be refrigeratedimmediately after removal from the carcass and frozen as quickly as possible.
- Fat that is to be stored longer than ten days should be stored at -20 degrees.
- Packages of fat should not be thicker than three inches. Fat that is packaged thicker than three inches does not chill as quickly in the center to properly freeze in time to retard growth of bacteria.
- Weight of the package should not exceed twenty pounds. When shipping fat to the processor, ship via refrigerated truck or place dry ice in the containers to keep the fat frozen.
NOTE: In reference to items 4 & 6: If the birds are "home processed", be sure to consider the following --- The "thermal mass" (the volume by weight and the temperature of the material) of both the fresh, warm fat being placed in the freezer and the amount of already frozen materials in the freezer will affect the rate at which the fresh fat will freeze. Be sure the amount of warm, fresh fat you put in the freezer is much less than the amount of already frozen material already in the freezer. It is suggested that when putting warm fat into the freezer, you also place some ice (in bags, etc) in the freezer to speed the chilling process.
