  • Title: EPR as an analytical tool in assessing the mineral nutrients and irradiated food products-vegetables.
    Author: Prasuna CP, Chakradhar RP, Rao JL, Gopal NO.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2008 Dec 01; 71(3):809-13. PubMed ID: 18372211.
    Abstract:
    EPR spectral investigations of some commonly available vegetables in south India, which are of global importance like Daucus carota (carrot), Cyamopsis tetragonoloba (cluster beans), Coccinia indica (little gourd) and Beta vulgaris (beet root) have been carried out. In all the vegetable samples a free radical corresponding to cellulose radical is observed. Almost all the samples under investigation exhibit Mn ions in different oxidation states. The temperature variation EPR studies are done and are discussed in view of the paramagnetic oxidation states. The radiation-induced defects have also been assessed by using the EPR spectra of such irradiated food products.
