Abstract
In accordance with the present invention, there are provided methods for defatting meat, comprising adjusting the temperature of raw meat material up to its corresponding species body temperature in the substantial absence of added reagents, and feeding said temperature adjusted raw material to a decanter centrifuge maintained under suitable conditions to form a meat layer, an intermediate boundary layer containing particles of fat tissue, meat and moisture, and a fat layer within the centrifuge. Liquid is metered into the temperature adjusted raw material entering the centrifuge in an amount sufficient to separate the meat layer form the other layers. Subsequently, a defatted meat is recovered.
Claims18
A method for defatting meat comprising:
- pumping raw meat starting material through a heating means to adjust the temperature of said raw material up to about the live body temperature of the corresponding species, then
- feeding said raw material into a decanter centrifuge maintained under suitable conditions to form a substantially solid layer of defatted meat, an intermediate boundary layer containing particles of fat, meat and moisture, and a substantially liquid layer of fat within the centrifuge by centrifugal separation, and
- metering liquid into the temperature adjusted raw material entering the centrifuge in an amount sufficient to separate the meat layer from the intermediate boundary layer and the fat layer during centrifugal separation in the centrifuge, then
- driving the boundary layer from the centrifuge along with the substantially liquid fat layer, and then
- recovering a defatted meat composition having a moisture content substantially the same as the natural moisture content of the raw meat starting material from the centrifuge.
A method for producing defatted meat from a fragmented raw meat starting material using a decanter centrifuge having a feed tube for discharging the fragmented raw meat starting material into a rotating bowl for separating the starting material into separate layers by centrifugal separation, comprising the steps of:
- pumping a fragmented raw meat starting material through a heating device to adjust the temperature of the raw material up to about the live body temperature of the corresponding species;
- introducing the temperature adjusted starting material into a feed tube of a decanter centrifuge;
- metering liquid into the feed tube along with the temperature adjusted starting material;
- discharging the contents of the feed tube into a rotating bowl of the decanter centrifuge to form a substantially solid layer of defatted meat and a substantially liquid layer of fat and;
- then
- driving the defatted meat layer from the centrifuge in the substantial absence of the fat layer, the defatted meat layer having a moisture content substantially the same as the natural moisture content of the raw meat starting material.
