Technology is based on spectroscopic methods of the near or medium infrared.

The Foundation for Auxiliary Technologies of Agriculture (Tecnova) The NIRSS technology project applied to the quality of horticultural products is carrying out. Its main objective is to determine the application of this technology for the classification of tomatoes based on its degrees Brix, o contained in sugars.

This parameter, that relates the concentration of total sugars of each product, It has been analyzed in RAF and Pear type tomatoes through the high -resolution liquid chromatography technique and the near infrared spectrum. Thanks to the data obtained, The necessary algorithms are determined to define an adequate level of Brix degrees and predict these chemical parameters in the selected samples.

And is that, Taking into account that consumers opt for the most mature and sweeter tomato fruits, In recent years, farmers have increased sugars content in their plantations.

Nir technology consists in the emission of a beam of light on a sample so that it absorbs a certain amount of radiation, either in the Nir region (Nir spectroscopy) or in the MIR region. Subsequently, The graphical representation of absorbed energy values, A giver of longitudes on the onda, results in a curve called spectrum.

From these, It is possible to relate spectral data to quantitative and/or qualitative attributes to estimate.

Among the advantages provided by this novel technique, the speed with which the analyzes are performed is carried out, allowing to obtain the results in a matter of minutes and, Therefore, make decisions at high speed. On the other hand, It is a non -destructive technique and clean technology, that does not alter the properties of the elements analyzed and does not use reagents or generate waste.
