The disclosure discloses a method for killing A. Flavus spores by infrared radiation in coordination with essential oil fumigation, and belongs to the technical field of sterilization. The method is to treat A. Flavus spores by medium and short wave infrared radiation in combination with essential oil fumigation. The disclosure provides a method for killing A. Flavus spores by medium and short wave infrared radiation in coordination with essential oil fumigation. On the one hand, air residual heat and energy of medium and short wave infrared radiation are fully used to make a material heated up rapidly, and on the other hand, essential oil on the surface of the material penetrates the cell membrane of A. Flavus spores, and further damages protein on the membrane and internal organelles in combination with the heat effect. The process is easy in operation, low in energy consumption, pollution-free and high in sterilization efficiency, and can be used for purifying bulk grains.

A food preservation system is provided. The system includes a storage cabinet for storing foods, an electrolytic gas generator, a gas sensor and a control unit. The electrolytic gas generator is in fluid communication with the storage cabinet to output a first gas and a second gas to preserve the foods. The gas sensor is arranged in the storage cabinet to detect the concentration of the gases in the storage cabinet for obtaining gas concentration information which includes a first gas concentration and a second gas concentration. The control unit is electrically connected to the electrolytic gas generator and the gas sensor. According to the received gas concentration information, the control unit adjusts the applied voltage of the electrolytic gas generator to control the gas species generated by the electrolytic gas generator and the first and second gas concentrations in the storage cabinet.

The present invention is directed to an integrated system of improving nut product safety, quality and production costs. Formulations and methods are provided for reducing pathogen contamination of nuts, improving storage stability of stored nuts and reducing refrigeration costs, and enhancing shelling operations by improving the contrast between nut shell fragments and nutmeats. The formulations may be used individually or in combination to provide all three commercial benefits of reduced bioburden, enhanced storage stability, and greater sorting efficiency of nutmeat from shell. The materials for the formulations disclosed herein are mostly derived from the waste materials of the species of tree that nut is harvested from and/or from other natural sources.
