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.

Various embodiments of the present invention relate to, among other things, a nano carrier platform for generating enhanced engineered water nanostructures (iEWNS) encapsulating and delivering reactive oxygen species (ROS) and, in some instances, other active ingredients, methods for inactivating at least one of viruses, bacteria, bacterial spores, and fungi on a substrate by applying iEWNS to the substrate.

Provided is an inorganic composite compound having reduced oxygen and a high reducing ability, which includes elements having a positive atomic valence of a plant-derived component and a sulfur compound. The compound provides a therapeutic treatment effect and a pharmacological effect and is useful to suppress the influence of active oxygen (oxidization) and cannot be produced by a synthetic chemical technique. A method of producing the same is also provided.

Systems and methods for packaging food products, such as fruits, vegetables, and meats. Specifically, the described methods relate to systems and methods for packaging food products in a manner that increases the products' shelf life. Generally, the methods begin by providing a food product. In some cases, debris is removed from the food product. To kill bacteria and other microbes on the food product, the food product is optionally washed in ozonated water. To deactivate enzymes within the food product, the food product is heated, though not necessarily cooked or blanched. The food product is then typically sealed in a barrier package containing between about 1 percent and about 50 percent oxygen, by volume. In some cases, the sealed package is then heated to between about 165 and about 285 degrees Fahrenheit to kill microbes in the sealed package. Other implementations are also described.
