PROBLEM TO BE SOLVED: To provide a method of manufacturing a canned product capable of accurate sealability inspection irrespective of a method of enclosing liquid nitrogen, irrespective of climate of a region of the manufacture and with an inhibited variation in internal pressure in a can. SOLUTION: The method of manufacturing a canned product includes steps of filling a can body with contents, enclosing the liquid nitrogen and sealing, and then carrying out the sealability inspection. The temperature of filling the contents is 30-50°C, an average of the internal pressure in the can is 0.3-1.0 kPa, and standard deviation is 0.12 or below. The invention is appropriate in particular for filling hypoacid beverage such as milk and coffee including milk-constituent-containing contents for retort sterilization. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To obtain a dairy food and drink, such as milk sealed in a transparent container such as PET bottle, and causing no off-flavor induced by light even being commodity displayed at a store, which is easily affected by sunlight or fluorescent lamp. SOLUTION: This dairy food and drink is obtained by packing contents in a transparent container which substantially shades light of a wavelength zone of 550-720 nm. The shading rate of the container in the wavelength zone is ≥50%. Dissolved oxygen concentration is preferably set to ≤8 ppm. As for the container, the material is preferably polyethylene terephthalate and polyethylene naphthalate. As a result of this, it is possible to watch contents from the outside and inhibit off-flavor occurrence by light. COPYRIGHT: (C)2007,JPO&INPIT
