Abstract

L’invention concerne une matière préservant la fraîcheur qui élimine les déversements d’eau, notamment en cas de renversement au cours du transport ou lors de la vente de fleurs coupées, et capable de préserver la fraîcheur de fleurs coupées plus longtemps que les matières préservant la fraîcheur de fleurs coupées comportant des fibres absorbant l’eau traditionnelles. La matière préservant la fraîcheur de fleurs coupées est caractérisée en ce qu’elle comprend des fibres absorbant l’eau dont l’absorption d’eau pure est comprise entre un facteur 10 et 100 et dans laquelle la valeur obtenue en divisant l’absorption d’eau pure par la quantité de groupements carboxy sous forme de sel (mmol/g) est comprise entre 5 et 50. Dans un mode de réalisation préféré, les fibres absorbant l’eau présentent une structure réticulée formée par liaison covalente.
