Method and apparatus for determining quality of fruit and vegetable products

摘要

A method for determining the quality and ripeness of fruit and vegetable products includes the steps of irradiating a fruit or vegetable product with radiating light; measuring the absorbance of the product at the wavelengths of 670 nm and 720 nm; determining the difference of absorbances measured at the wavelengths of 670 nm and 720 nm.
