Method for the contactless determination of features of meat quality
First Claim
1. A method for contact-free analysis of fat/meat quality of a meat product, comprising the steps of:
- radiating the meat product with a scanning light source which creates a moving point of light on the meat product;
detecting continuous radiation emanating from the moving point of light on the test object and periodically converting a detected continuous radiation into definite radiation values corresponding to the point of light at scanned locations on the test object;
providing reference values which are known radiation values corresponding to fat and meat portions of a reference meat product;
comparing the reference values to the definite radiation values to create a first group of the definite values corresponding to fat portions and a second group of the definite values corresponding to meat portions of the meat product; and
comparing the two groups of values to determine fat/meat quality.

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.
