摘要： The invention relates to a method and an apparatus for determining the quality of fruit and vegetable products. The method comprises the following steps:irradiation of a product with light radiation with at least a wavelength centred on the values 670 nm±50 nm;measuring of the absorbance of the radiation with wavelength of 670 nm and 720 nm return wavelength from the product;calculation of the absorbance difference between the values of the wavelengths at 670 nm and at 720 nm;obtaining from said difference an index the value of which is correlated with various parameters of the quality of the product: hardness of the pulp, Brix grades, ethylene concentration, etc.The apparatus, which can be portable, comprises: a radiating light source with at least a wavelength of 670 nm±50 nm; a sensor suitable for collecting part of the radiation reflected by the product and connected, by means of an optic fibre beam, to a detector unit comprising possible optic filter means and a detector, a central control and processing unit of the detected signals and a display for displaying the result of the reprocessed signals.
