  • Title: [Electron spin resonance measurements on dried fruit. Carbohydrate composition and ESR signal structure of irradiated fruit].
    Author: Mischke J, Helle N, Linke B, Schreiber GA, Bögl KW.
    Journal: Z Ernahrungswiss; 1994 Dec; 33(4):258-66. PubMed ID: 7732704.
    Abstract:
    While in a previous work the ESR spectroscopic detection of irradiated dried fruits was reported, in this paper liquid chromatographic determination of the carbohydrate fraction of these fruits is introduced and connected with the ESR results. After irradiation of dried fruits three different types of ESR spectra are observed. In most cases the dried fruits can be attached to these various types by means of their sugar composition. It was also found that the ESR spectra observed for sucrose-rich fruits are very similar to that of pure sucrose. The structure of the ESR spectra can change with storage. Probably, radical rearrangement reactions in the samples are responsible for these changes.
