Apparatus for inspecting food

摘要

A food inspection apparatus 1 includes a light source or a plurality of light sources 10 that outputs near infrared light L1, and a detector unit 20 that measures a diffuse reflectance spectrum of light which is the near infrared light L1 and is diffusively reflected from an object 50 from among. The light source 10 and a detector unit 20 are arranged such that an angle defined by an optical path L2, along which the near infrared light is regularly reflected at a surface of the object, or an optical path L5, along which the near infrared light is transmitted through the object, and a straight line L3 or L6 connecting an irradiation position P1 or P2 on the surface of the object irradiated with the near infrared light and the detector unit 20, is 45 degrees or greater.
