ABSTRACT:
There is disclosed an apparatus and method for inspecting the contents, such as food, of a package, particularly a light-opaque package, for degradation or the degree of degradation by means of ultra-soft X-rays. The inspection apparatus generally comprises a shaking unit for shaking the package and a main inspecting unit disposed downstream and independently of the shaking unit. The assessment of degradation of the degree of degradation can be made according to the state of dispersion, after shaking, of the package head space in the X-ray image information. The method and apparatus eliminate losses arising from destructive inspection.
