Abstract

La présente invention se rapporte à la production de produits sous forme de purée à partir de matières végétales, en particulier à des procédés et à des dispositifs permettant de produire un produit fonctionnel composé de baies rendues en purée comportant des graines broyées et les peaux des baies et enrichi avec le contenu des graines et des peaux tels que les acides gras polyinsaturés, les vitamines solubles dans les graisses, les polyphénols, parmi ceux-ci des anthocyanines présentant une meilleure activité antiradicalaire, le contenu n'étant pas disponible dans l'organisme humain lorsque les baies sont traitées par des procédés traditionnels. Le procédé est basé sur le traitement de la matière première dans des circuits hydrodynamique, la matière première étant soumise à une oscillation de pression, un frottement turbulent et une implosion des bulles de cavitation avec le chauffage résultant et des phénols peuvent être isolés de la matière première selon une manière qui réduit à un minimum leur capacité destructrice inhérente. Le dispositif permettant la mise en œuvre du procédé comprend un appareil à écoulement continu (1), un dispositif (5) permettant d'éliminer l'air de la matière première, une pompe (6), un déflecteur hydrodynamique (7) et un séparateur centrifuge (9), tous ces éléments formant un circuit hydrodynamique fermé principal (8), ainsi qu'un canal de dérivation (10). À la fois le procédé et le dispositif permettent de produire un produit ayant un goût remarquable et des propriétés fonctionnelles utiles ainsi qu'une longue durée de conservation.
