Definitions

• the present invention relates to a method of serving a beverage contained in a plastic container by heating the same to, for example, 45 - 90 degrees Celsius.
• beverages are filled in plastic containers at a relatively high temperatures and are heated before they are served to consumers. If beverages are filled in plastic containers at a high temperature, the pressure inside the containers will decrease at normal temperatures. As such, the pressure inside the containers will not rise too much even when the beverages are heated, and deformation of the containers was avoided.
• the present invention provides a method of serving heated beverages, which is characterized by the steps of: filling a non-carbonated beverage in a plastic container at a normal temperature, injecting carbon dioxide gas into the head space of the plastic container filled with the non-carbonated beverage to replace a portion of the air inside the head space, capping the mouth of the plastic container in which a portion of the air inside the head space has been replaced with carbon dioxide, and serving the beverage sealed inside the plastic container to consumers by heating the same.
• Figure 1 shows the chronological changes in the bottom dimension of the plastic containers.
• Figure 2 shows the chronological changes in the girth of the plastic containers.
• Figure 3 shows the chronological changes in the total height of the plastic containers.
• thermo-plastic resin such as polyethylene, polypropylene, and polyethylene terephthalate is subjected to blow molding, injection blow molding, stretch blow molding or the like to produce plastic containers to be used in the present invention.
• Plastic containers thus produced and caps are subjected to sterilization treatment using hot water or chlorine- base bactericide and fed to sterile filling device.
• Beverages to be filled include non-carbonated beverages such as green tea, Oolong tea, black tea, milk tea, black coffee, milk coffee, and fruit juices.
• a non-carbonated beverage is filled in a plastic container using known sterile filling device in a sterile air atmosphere at 5 - 40 degrees Celsius, more preferably at a normal temperature between 15 - 35 degrees Celsius.
• the container In the head space of the plastic container filled with non-carbonated beverage is injected carbon dioxide gas, or a gas mixture containing carbon dioxide and nitrogen gas and the container is sealed with a cap.
• carbon dioxide gas or a gas mixture containing carbon dioxide and nitrogen gas
• the container is sealed with a cap.
• the air inside the head space is replaced with carbon dioxide gas.
• 30 - 60% of the air in the head space is replaced with carbon dioxide gas.
• the air in the head space, particularly oxygen is preferably replaced with as much carbon dioxide as possible in order to prevent oxidation of the contents in the container.
• the amount of oxygen content is preferably less than 1 mg/100 ml.
• the containers are heated to 45 - 90 degrees Celsius, preferably to 50 - 60 degrees Celsius in an automatic vending machine with heating device, warmer apparatus, etc. to be served to consumers.
• Green tea, milk tea, and milk coffee were filled into 280 mol polyester bottles produced by Ishizuka Glass Co. using sterile filling line manufactured by Dainippon Printing Co. Ltd.
• carbon dioxide gas was injected from the mouth of the bottle to replace the air inside the head space of the product.
• nitrogen gas was used to replace the air inside the head space of the product under the same conditions.
• Liquid temperature 25 - 30 degrees
• Filling rate 600 bottles/minute
• Bottles filled with green tea in accordance with Example were immersed in a hot bath at 85 degrees, and chronological changes in the bottom dimension, the girth and the total height were measured. The result is shown below.
• Carbon dioxide gas is contained in the head space of the plastic container provided according to the present invention, and a portion of carbon dioxide has been dissolved in the beverage.
• the pressure inside the plastic container is decreased to below the atmospheric pressure. As a result, it becomes possible to minimize deformation of the container due to expansion of the gas inside the head space that is heated by heating mechanism built in the automatic vending machine, warmer device or the like.
