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.

Methods and compositions for inhibiting or dispersing biofilms produced by Listeria monocytogenes on plant matter are described. Embodiments include using formulations comprising active chemical constituents and aqueous extracts or sap from certain trees. Methods of using and producing aqueous formulations derived from hickory and maple wood are provided. Formulations and methods are provided for preventing and dispersing exopolysaccharide-rich listerial biofilms.

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.

Disclosed herein are embodiments of a composition comprising at least one cellulose material (such as a cellulose nanomaterial) and an optional inorganic salt component. Some embodiments of the composition can further comprise additional components, with some embodiments further comprising a non-starch polysaccharide (e.g., methyl cellulose carboxymethyl cellulose or other cellulose derivative, chitosan, or the like), a surfactant, a plasticizer, an antimicrobial component, or any combination thereof. The disclosed compositions are useful for forming edible coatings/films on plants, plant parts, and other objects. The disclosed compositions and coatings/films made using the compositions are effective at protecting fresh and processed produce and other substances and products, from various different types of food processing damage (and the deleterious effects associated therewith).
