A system and method for decontamination of product is described. An object to be treated, which may be a food product or a medical device, is placed in a substantially closed dielectric container with a working gas. The container is placed in an apparatus capable of producing a controlled electrical discharge so as to create reactive ion species within the package. The object to be treated may be exposed either the immediate products of the electrical discharge or the long lasting reactive ion species, or both, so as to treat the object to reduce or eliminate specific contaminants, which may be biological pathogens or the cause of product spoilage, or inorganic contaminants. The reactive ion species may result from an atmospheric non-equilibrium plasma (ANEP) formed by the apparatus and the treatment may be performed without significantly increasing the bulk temperature of the object being treated.

A fresh food preservation equipment is provided, includes a preservation box formed with a cavity therein, an atomization device configured for outputting water mist to the plasma activated droplet generating device, a plasma activated droplet generating device configured for ionizing the water mist output from the atomization device and feeding a resultant activated mist into the cavity, a refrigeration device configured for reducing temperature inside the cavity, a sensing system includes an oxygen sensor, a humidity sensor, and a temperature sensor for monitoring oxygen concentration, temperature and humidity in the cavity, respectively, and a control unit. Compared with the prior art, the fresh food preservation equipment in the present disclosure achieves the effects of keeping moisture and reducing the respiration intensity of fruits and vegetables while keeping fresh, and the quality of fresh food is effectively ensured, so that the shelf life is prolonged.

Described is a method for preparing a nut paste, comprising the steps of: a) treating the surface of nutshells and/or non-shelled nuts to remove surface contaminants from the shell material; b) preparing a mixture comprising: b1) surface-treated non-shelled nuts, b2) shelled culinary nuts and surface-treated nutshells, and/or b3) shelled culinary nuts and surface-treated non-shelled nuts; and c) grinding the mixture to an average particle size of 500 m or less to provide a nut paste; wherein the mixture contains at least 0.05 wt.-% of surface-treated nutshell material based on the total weight of solids, and wherein the mixture does not contain added water. The method enables optimized extraction and yield of nutritionally beneficial components of both nut kernels and nut shells while enabling fast and inexpensive processing. In addition, a nut paste obtainable by the aforementioned method and the use of surface-treated nut shells and/or surface-treated non-shelled nuts in ground form as filler material in the preparation of food is described.

Disclosed is a radiant catalytic ionization detoxification system including a gas-liquid mixer configured to gas-liquid mix air carrying radiant catalytic ionized Reactive Oxygen Species with liquid material to be detoxified, and a reaction tube configured to circulate the mixed gas-liquid mixture. The detoxification system of the present disclosure is applicable to water sterilization or aflatoxin removal in edible oils. The radiant catalytic ionization chamber in the system can provide the system with air containing Reactive Oxygen Species, wherein mesh panels coated with photocatalytic materials are configured inside the chamber body, which configuration not only increases the photocatalytic material content per unit volume, but also expands the light-exposed surface area due to uniform distribution of the photocatalytic materials on the mesh panels. The system uses a U-shaped tube as the reaction tube, and the length of the reaction tube can be freely designed according to the practical detoxification requirements.

The present invention provides strategies to use and control the delivery of ionizing radiation to carry out therapeutic and industrial irradiation treatments. The present invention uses partial pulse control, component selection, and/or component configuration strategies in order to accurately monitor and terminate irradiation. The strategies are particularly useful to control dosing in the high dose rate and short time scales associated with FLASH technology.
