1,193,844. Quality testing of meat. SLAGTERIERNES FORSKNINGSINSTITUT. 18 Aug., 1967 [23 Aug., 1966], No. 38214/67. Heading A2U. [Also in Divisions A5, G1 and G2] A device to be inserted into an animal carcase for determining the quality of the meat comprises a probe having a front cutting edge 3 and a window 8 for the observation of a first meat area adjacent the window, a light source 6 for illuminating a second meat area situated opposite to the first meat area, and means for the interception of light from the first area and comparison of the colour characteristics of this light with those of the light which strikes the second area. As shown, the device comprises a probe part 2, a lance member 4, and a photoelectric cell 14 which receives, via a mirror 19 and a window 8 light from a lamp 6 in the lance member which has passed through meat into which the device has been inserted. The quality of the meat can be judged by noting the output of the photo-electric cell recorded on a meter 12. It is stated that the cell 14 and motor 12 may be replaced by an eyepiece by which the light from the meat may be viewed and compared with a colour chart and that the device may incorporate light conducting rods. The meter 12 may be contained within the handle 1 and the device may include a scale or a stop for checking penetration. In an alternative embodiment, Fig. 2 (not shown), the lamp 6 is contained within the probe part 2 which is channelshaped and the light is directed across the channel. |
