A method for treating a perishable product is provided, the method comprising: determining a desired product treatment outcome selected from sanitization, protection, preservation, or enhancement of the perishable product; after harvesting, wet or dry washing the perishable product; directly or indirectly applying a substance to the surface of the perishable product using a carrier; and packaging the perishable product. A system for treating a perishable product with a substance treatment is provided, the system comprising: one or more devices for directed substance application to a surface of the perishable products prior to final packaging of the perishable product using a carrier; and wherein the one or more devices is an electrostatically charging device or a nebulizer. Embodiments of the invention which use multiple, sequenced, and engineered applications enhance the efficacy of sanitizers and other functional substances for increasing the quality, safety, and overall shelf life of perishable products.

A liquid nitrogen quick-freezing preservation method for fresh bamboo shoots. The method includes performing a coating treatment on cuts of fresh bamboo shoots, which reduces the moisture loss through the cuts, slows down the degree of lignification of the bamboo shoots, mitigates color changes at the cuts, inhibits excessively fast reproduction of microorganisms at the cuts and prevents invasion of microorganisms from the cuts, so that a decrease in nutritional value is reduced, the deterioration of the appearance quality of the bamboo shoots is mitigated, and the nutritional value and commodity value of the bamboo shoots are maintained. The method further includes an intermittent ultrasonic treatment on the fresh bamboo shoots, so that coating substances form films on the surfaces of the cuts more easily, preventing the fresh bamboo shoots from being eroded by microorganisms and preventing nutrient substances from being decomposed and utilized by the microorganisms.

Fluence non-uniformities across a surface portion of a target (organism or inanimate object) due to inherent non-uniformities in the irradiation beam and/or shadowed target surfaces, are known to limit the effectiveness of target kinetic processes responsive to wave energy irradiation (electromagnetic, EM, elastic, EL, and/or quantum particle, QP). A field of scattering particles (e.g., bubbles in water, aerosols such as dry fog, powders, etc.) is constructed spatially/temporally in the vicinity of the target and in the path of propagating wave energy to improve the fluence coverage and thereby enhance the overall effectiveness of the kinetic process. The scatterers can be added to an existing irradiation system (retrofit application) or added to the design of a new system (forward fit). Novel dosimeters and methods of dosimetry are also disclosed to more accurately characterize the fluence received over complex surfaces.

A disinfectant device provides a solution to disinfect bulk quantities of small items such as food items. The disinfectant device has a housing, an inlet, an outlet, a shaker tray positioned to descend from a first height on the inlet side to a second height on the outlet side, the second height lower than the first height, wherein the shaker tray is configured to shake or vibrate via a motor, and at least one disinfecting light is positioned within the housing and above the shaker tray, the light configured to disinfect items passing on the shaker tray. The disinfectant device may have a hopper having a gate to the shaker tray. The gate may be manually operated or actuated by a motor to control the number of items on the shaker tray at any given time, thereby ensuring adequate exposure to the disinfecting light.

Disclosed herein is a plasma coating system, including a plasma treatment device configured to generate a plasma discharge to treat a product; a coating station that treats the product with a liquid coating; and a transport surface that transports a product from the plasma treatment device to the coating station.
