Systems and methods for treating large quantities of potatoes, other tubers, vegetables, produce, and/or other crops are disclosed herein. In one embodiment, a crop storage facility configured in accordance with the present technology includes a treatment system configured to distribute a treatment agent configured to inhibit spoilage of the crops. The treatment system can include a combination of two or more chemical compositions configured to release different concentrations of the treatment agent to produce a desired level of the treatment agent in the storage facility.

A multilayer medical packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.

The invention relates to a tubular filter that absorbs ethylene or other gases for refrigerated transport containers, formed by a cylindrical tube of plastic mesh (2) with hermetic caps (3) at both ends, which contains granules that absorb ethylene or other gases, the mesh (2) having a structural configuration formed by an inner crown (20) having a circular filament (201), and an outer crown (21) having a wing-shaped filament (211), the base thereof being wider than the distal end thereof, thereby facilitating the entry of air flow into the tube. It further comprises a support accessory (4) fixed in the container for which the filter (1) is intended, and it has an aerodynamic shape that helps to increase air flow through the filter (1) and liquid collection means.

Facilities for storing large quantities of potatoes, other tubers, vegetables, produce, and/or other crops are disclosed herein. In one embodiment, a facility configured in accordance with the present technology circulates air from a pile of potatoes into one or more ceiling cavities above the potatoes to warm ceiling panels. Aspects of this embodiment can reduce undesirable water formation on the potatoes.

A method for preserving Ziziphus jujuba, including: 1) preservation treatment of the Ziziphus jujuba harvested by a) fumigation and b) soaking the Ziziphus jujuba in a liquid preservative at room temperature; 2) air-drying the soaked Ziziphus jujuba and placing it into polyethylene bags, and then placing the Ziziphus jujuba into an inner atmosphere of a jacketed cold and controlled atmosphere storage warehouse and cooling it at 4 C. for 24-48 hours; and after slowly reducing the temperature of the inner atmosphere to 3.00.1 C. over a period of 6 days, closing off the inner atmosphere and controlling its composition. During the cooling step, air is circulated between the inner atmosphere and the outer atmosphere of the jacketed cold and controlled atmosphere storage warehouse.

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.
