Provided are a freshness retaining agent that can be obtained by a simple method and exhibits excellent adsorption performance and antibacterial activity, a gas purification device including the freshness retaining agent, and a gas purification system. The freshness retaining agent is formed by adhering tea catechins to a surface and/or an inside of charcoal powders and adhering the charcoal powders to each other with clay interposed between the charcoal powders, thereby exhibiting excellent adsorption performance and antibacterial activity.

The present invention provides a method of preserving cut roses in the absence of a water supply. The method comprises: (a) cutting roses having a flower bud or a bloomed flower; and (b) packaging the cut roses in a container without immersing or inserting the stems in a hydration system. Instead, the cut roses are treated before or during the packaging by applying a preservation composition onto the flower buds or bloomed flowers The preservation composition contains at least 5 ppm of plant hormone selected from cytokinin, gibberellins and combinations thereof. A flower shipment kit is also disclosed.

A composition for preventing fungal spoilage in post-harvest fruits, vegetables and flowers, method and use thereof is provided. The composition has beta-cyclocitral (-cyclocitral) as the only active ingredient that inhibits or delay fungal growth on post-harvest fruits, vegetables and flowers and provides excellent results in the preservation and the shelf life of these products. Furthermore, the method for preventing fungal spoilage in post-harvest fruits, vegetables and flowers is carried out by applying the composition through different techniques directly to the products or on the surface of the container or package.

The invention provides a flower shipment kit comprising: a container holding an aqueous flower gel; and one or more cut flowers whose stems are immersed in the aqueous flower gel; wherein the aqueous flower gel comprises (i) 1-4 wt. % of disc-shaped smectite clay nanoparticles having two opposing flat surfaces that are negatively charged and a rim that is positively charged, and (ii) 0.01-250 mM of one or more gel destabilizing agents selected from acidulants, dissolved metal cations and dissolved ammonium cations. The flower gel of the present invention slowly releases water over time in a way that enables cut flowers to take it up immediately. The invention also relates to a kit of parts for preparing a gelled hydration medium and to a method of preparing such a gelled hydration medium.
