Method of inspecting food and inspection apparatus implementing the same

摘要

A method of inspecting food (50) which can evaluate quality of the food with improved precision includes steps of irradiating probing light (L1) having near infrared wavelengths on the food (50); detecting light (L3) diffusively reflected by the food (50) to obtain a reflectance spectrum; obtaining an absorbance spectrum based on the reflectance spectrum; and evaluating the food (50) using the reflectance spectrum and the absorbance spectrum. An apparatus for implementing the method includes: a light source unit (10) to generate probing light which has near infrared wavelengths and illuminates the food (50); a detector unit (20) to detect light diffusively reflected by the food (50) to obtain a reflectance spectrum of the food; and a processing unit (40) to evaluate the food based on the reflectance spectrum and an absorbance spectrum calculated from the reflectance spectrum.
