A process and an apparatus for controlling temperature loss and shrinkage of meat after an animal is slaughtered for food. Shrinkage is controlled by compressing the meat during cooling, the compression offsetting a natural tendency of the meat to contract and providing a measure of control over the shaping of the meat. Apparatus for the process includes one or more rigid rings for placement around the meat. Each ring is wrapped with a thread secured rigidly to one side of the ring and secured movably to the other side such as to allow the length of thread on the second side of the rigid ring to form at least one winding around the meat. As the meat cools, the thread shrinks, applying the thermal contraction of the thread along the ring to constrict the winding around and thus longitudinally elongate the meat.

A container refrigeration apparatus includes a CA system which controls the composition of the air in the container. The CA system includes a gas supply device which supplies nitrogen-enriched air, an intake duct which guides outside air to a first space on a suction side of an interior fan, and an exhaust duct which guides air in a second space on the blowout side of the interior fan out of a container. The exhaust duct has an inlet at a location where the flow of the air blown from the interior fan is blocked by a fan housing.

Composite materials comprising a phase change material (PCM) and a macroscale 3D carbon nanotube material, such as a macroscale 3D heteroatom-doped carbon nanotube material, including boron doped carbon nanotube materials, and methods for using the composite materials in various applications where temperature control is critical. Heteroatom-doped carbon nanotube sponge materials are strongly oleophilic, and can soak up large quantities of organic PCMs. One representative application for the composite materials is in thermal energy storage (TES) systems for shipping and storage of pharmaceuticals, medical and life science products.

Disclosed are a disinfection and sterilization apparatus and method for a refrigerated container transportation system. The disinfection and sterilization apparatus comprises a to-be-treated waiting area, a disinfection and sterilization system, a treatment waiting area and a central control system, wherein a first prompter is arranged in the to-be-treated waiting area; the disinfection and sterilization system comprises a disinfection and sterilization bin, a vacuumizing device and an ozone supply device; a disinfection and sterilization bin inlet and a disinfection and sterilization bin outlet are respectively formed in the left side and the right side of the disinfection and sterilization bin; the top of the disinfection and sterilization bin is provided with a detaching and hanging device for detaching or hanging a refrigerated container and a transportation vehicle; a second prompter is arranged in the treatment waiting area; and the central control system is connected with the first prompter, the disinfection and sterilization bin inlet, the disinfection and sterilization bin outlet, the detaching and hanging device and the second prompter through data transmission lines. According to the disinfection and sterilization apparatus and method, a new coronavirus propagation path of cold-chain food in the refrigerated container can be effectively, and particularly, adverse effects of disinfection and sterilization apparatuses on parts such as engines and tires of transportation vehicles in the vacuumizing and ozone injection processes can be avoided.

The disclosure relates to methods for operating a pasteurizing device for pasteurizing foods filled into sealed containers. The foods are treated in treatment zones by applying a tempered, aqueous treatment liquid to an exterior of the containers. The treatment liquid is re-supplied to at least one treatment zone for reuse via circulation circuit pipes of a circulation circuit. A partial flow of the treatment liquid is continuously removed from the circulation circuit and filtered by means of a membrane filtration means. Furthermore, a biocide is apportioned to the treatment liquid as process chemical, such that a concentration of the biocide does not exceed 0.4 mmol/L. In addition, a pH-regulating agent comprising at least one inorganic or organic acid is apportioned to the treatment liquid as process chemical, such that a pH value of the treatment liquid is set to a range from 3.5 to 7.0.

The purpose of the present invention is to provide a method of manufacturing a packaged frozen food product as well as a food packaging film and a packaged frozen food product, in which savor of freshly made food can be experienced when opening the package after thawing the frozen food. This method of manufacturing a packaged frozen food product comprises a packaging step of hermetically packaging food in a film including a gas barrier layer after baking or steaming the food and before temperature of the food drops to room temperature, the food being unbaked confectionery, semi-baked confectionery, bread, or rice cake; and a freezing step of freezing the food packaged in the packaging step, and obtaining frozen food.

A method for the provision and conservation of communal meals is provided, in which a plurality of foodstuff and meal components are brought into packaging units and sealed therein following the preparation of said food by heating at a temperature of at least 75° C. A water bath at a temperature of less than 3° C. is used to cool the sealed packaging units in order to bring the meal component from a core temperature of 65° C. or higher to a core temperature of 3° C. or lower within no more than 90 min. Methods for regenerating the cooled packaging units for consumption are also provided, in a water bath having a temperature of 80°-90° C.

A packaged frozen drink base contains an unpasteurized frozen aqueous antioxidant composition having a pH of 4 or less and packaging formed of a sealed waterproof tube having the frozen aqueous antioxidant composition disposed therein.
