Descripción :	We report here on the use on the photoacoustic technique for the determination of low concentrations of total iron in corn meal samples. The determination of this element in food is of considerable interest because several foods are currently enriched with it at propers levels in order to increase the resistance of people, after consumation, to several diseases, such as anemia. The proposed technique es based of an open photoacoustic cell configutration in conjunction with a suitable calorimetric method. We applied it to a measurement of a total iron concentration in corn meal samples. The results agree very well with those obtained using a conventional spectrophotomeric method showing the possibilities of new experimental methodologies based on photothermal methods to perform this kind of study with the advantage of a higher sensitivity and increment of the range of appreciable absorbance.
