Title:
MEAT COLOR GRADE DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/176114
Kind Code:
A1
Abstract:
Without relying on a subjective assessment, the invention provides a meat color grade determination standard creation method and a meat color grade determination method that enable detailed meat color grade determination and automation of meat color grade determination. The invention is related to the meat color grade determination standard creation method, in which: (1) a digital image is extracted from the surfaces of multiple meat specimens; (2) a CIELab value for each meat specimen is found from an RGB value of the extracted digital image; (3) a grade of meat color is determined for each meat specimen; and (4) a meat color grade determination standard is found from the relationship between any two factors and the grade, said factors being of the CIELab values found for the multiple meat specimens. Moreover, the invention is related to a meat color grade determination method containing a step in which: (5) for the meat specimens, which are items for inspection, steps (1) and (2) are performed to find the CIELab values, and in reference to the meat color grade determination standard obtained by step (4), the grades of the meat colors of the meat specimens that are the items for inspection are found.
