There are provided methods of treating edible matter comprising applying a composition comprising performic acid to the edible matter or a substrate therefor. Other embodiments are also disclosed.

A feedback system that identifies characteristics of an object and utilizes the characteristics to initiate and adjust a field applied to the object is provided. Fields can be applied to a particular portion of an object based on characteristics of the object, including location and thickness of the object, through one or more meshes. Sensors are utilized during supercooling to monitor a condition of the object being supercooled. Specifically, characteristics of the object are measured at different points, areas, or volumes on the object and the measurements are used to determine whether supercooling (or another desired result) is being achieved or whether the object is starting to freeze. Based on the measurements, parameters of the field can be adjusted to ensure supercooling of the object without freezing.

A food management system is provided. The food management system includes a plurality of electrodes arranged to be spaced apart from each other with food therebetween, a frequency modulator configured to adjust a frequency of power supplied to the plurality of electrodes, memory, comprising one or more storage media, storing instructions, and at least one processor communicatively coupled to the plurality of electrodes, the frequency modulator, and the memory, wherein instructions, when executed by the at least one processor individually or collectively, cause the food management system to control the frequency modulator such that power at each of a plurality of frequencies is sequentially supplied to the plurality of electrodes, determine a resonance frequency based on an impedance of the food at each frequency, determine a state of the food based on the resonance frequency of the food, and perform an operation corresponding to the determined state of the food.

Systems and methods disclosed herein provide an improved high voltage plasma-based product treatment by integrating the plasma reactor into the processing container. This unique device can deliver a high throughput rate of raw food, without adverse effects on quality. The system is operationally efficient, and is capable of being scaled up or down to provide lower or higher throughput rates, depending on the product manufacturer or processor's needs. In particular, the system obviates the need for further containerization or packaging of product during pasteurization processing.
