| dc.description | The optical absorption centers in corn pericarp biopolymers have been studied by photoacoustic spectroscopy and the phase-resolved technique. The results show that the optical absorption spectra of these samples are formed by the superposition of two absorption bands, one of this corresponding to the cellulose in the epidermis and the other to o-gluciside pigments of flavonoid type wich are bound to the cellulose sugars. A spatial separation was obtained of the materials responsible for these absorption bands as a functions of the Ca(OH)2 concentration used in the alkaline cooking process which is the result of hemicellulose dissolution in these biopolymers. | - |
