Patent ID: 7345008

Claim:
A harvested plant freshness-keeping composition comprising at least one surfactant (A), wherein said surfactant has a sugar structure or a sugar alcohol structure, and at least one selected from the group consisting of a sugar (B), a plant hormone (C), an aging inhibitor (D), an aggregating agent for colloidal particles (E) and a germicide, fungicide or preservative (F); wherein either a hydrophobic group is bound via a glycoside linkage to the sugar or sugar alcohol in the component (A) and said component (A) is at a concentration of 0.0001 to 0.1 percent by weight of said composition, a hydrophobic group is bound via an ester linkage to the sugar or sugar alcohol in the component (A), or a hydrophobic group is bound via an amide linkage to the sugar or sugar alcohol in the component (A); the ratio of (A)/(B) by weight is 0.00001 to 2.0; the ratio of (A)/(C) by weight is 0.0002 to 10000; the ratio of (D)/(A) by weight is 0.0002 to 1000; the ratio of (A)/(E) by weight is 0.0002 to 1000; or the ratio of (A)/(F) by weight is 0.00001 to 200; component (C) is at least one selected from the group consisting of a natural auxin, synthetic auxin, natural cytokinin, synthetic cytokinin and gibberellin; and said composition comprises 0.0001 to 0.5% by weight of component (F).
