An improved method is provided for inactivating microorganisms in food products by introducing an edible phenolic compound in a food product and subjecting the resulting food product containing phenolic compound to high pressure conditions. This particular combination of physical and chemical treatments on the food products inactivates undesirable microorganisms in a food product to a significantly greater degree possible than achieved with any one of the treatments by itself, and the combined antimicrobial effect of these different types of treatments is synergistically greater than any additive effect that might be expected from the individual treatments.

The invention discloses a superhigh-temperature composting method for livestock and poultry manure. The method comprises the following steps: adjusting the water content of livestock and poultry manure to 45 to 60% by using a conditioning agent and then adding a decomposition bacterial strain for organic materials; then heating a mixed material, allowing the temperature of the mixed material to rise to 80 to 85 DEG C within 1 to 2 h and maintaining the superhigh temperature for 16 to 24 h to accomplish composting fermentation, wherein a high-pressure fan carries out aeration or stirring on the material for oxygen supply during fermentation; and after completion of fermentation, allowing the water content of an obtained composting product to fall to 20 to 30%, wherein the composting product allows the germination rate of seeds to reach 95% or above. The composting method provided by the invention can realize rapid decomposition of livestock and poultry manure, and the prepared composting product is thorough in inactivation of pathogenic organisms and low in loss of carbon and nitrogen and has substantially better fertilizer efficiency compared with traditional composting products.

The invention utilizes multiple frequency ultrasound generators driving multiple frequency harmonic transducer arrays at sweeping frequencies into the megasonic range. Generator signals that increase cavitation efficiency and that have successive time periods with predominantly stable cavitation and predominantly transient cavitation further improve the performance of the cleaning, microbiological inactivation, sonochemistry or processing systems. Probes that monitor the ultrasound and feedback the information to the generator provide consistency of process.

A method of microbially deactivating items and storing the same, comprising the steps of: a) placing items within a cavity in a sealable container having fluid access ports therein, the fluid access ports having a normally closed position and being moveable to an open position; b) placing the container having items to be microbially deactivated in the cavity into a reprocessor having a circulation system for circulating a microbial deactivation fluid during a deactivation cycle, wherein the fluid access ports in the container are moved to the open position by actuating means on the reprocessor to be in fluid communication with the circulation systems; c) circulating the microbial deactivation fluid through the cavity of the container; and d) removing the container from the reprocessor following a deactivation cycle, wherein removal of the container from the reprocessor causes the fluid access ports to assume the normally closed position.

The invention utilizes single and multiple frequency ultrasound generators driving single and multiple frequency resonant and harmonic transducer arrays at frequencies into the megasonic range. Generator signals that increase cavitation efficiency improve the performance of the cleaning, microbiological inactivation, sonochemistry or processing systems.
