ABSTRACT:
A method and apparatus is disclosed for the contact-free determination of features of quality of a test object selected from meat products. In one embodiment the test object is radiated with a light source. Radiation emanating from the test object is detected to create definite radiation values. These definite radiation values are then analyzed, preferably in comparison to the reference values. In another embodiment, a scanning device is employed for the production of a scanning ray. The scanning ray is deflected over the test object and a detector is employed for determining characteristics of points on the test object scanned by the scanning ray. With the method and apparatus disclosed, quality features such as the fresh condition, color and meat/fat ratio of the meat may be determined.
