Radiochemistry and radiopolymerization of polysaccharides
Description
The effects of gamma radiation on dry state polysaccharides (example: starch) are presented in an overall manner by order of quantitative importance: recombination of radicals to recover the initial macromolecule (cage effect) or smaller molecules which are chemically identical (radiopolymerization) and evolution of radicals to give secondary reactions (formation of radiolysis products). The effect of the botanical origin of the starch studied is briefly discussed, applications and extensions to the case of radiochemically induced modifications to foodstuffs being envisaged

Les effets du rayonnement gamma sur les polysaccharides a l'etat sec (exemple de l'amidon) sont presentes de facon globale et par ordre d'importance quantitative: - recombinaison de radicaux pour redonner la macromolecule initiale (effet cage) ou des molecules plus petites mais chimiquement identiques (radiodepolymerisation); - evolution des radicaux pour donner des reactions secondaires (formation de produits de radiolyse). L'influence de l'origine botanique de l'amidon est brievement discutee en vue de l'application et de l'extension de l'ensemble de ces resultats au cas des modifications chimiques radioformees dans les alimentsFiles
