ABSTRACT:
An apparatus, system and method are provided for determining the percentage of fat in a meat sample through the use of X-ray radiation techniques. An automatic calibration feature eliminates the need for manual potentiometer adjustments for accommodating interaction between X-ray attenuation by pairs of calibration standards of known fat percentage values for a given meat species. Protein and moisture percentages may be determined. Indicators for needed periodic recalibration also may be included, and adjustments may be incorporated for meat samples of high, normal or low moisture content, as well as for different species of meat.
