Abstract: A method of manufacturing a high quality beverage capable of providing beverage by an extraction after roasting the material thereof and filling beverage of a roast material in a container and sealing the container. The method comprises a step for roasting the material in a sterile atmosphere, and extracting the roast material or preparing a suspension of the roast material with sterilized water, wherein sterilized inert gas atmosphere is used as the sterile atmosphere in at least a part of the step, whereby since both the deterioration of quality due to oxidation and the deterioration of quality by heating can be prevented, the high quality beverage of the roast material can be manufactured.

Abstract: A thermoplastic resin composition containing an oxygen-absorbing agent, wherein a resin matrix of the thermoplastic resin composition is substantially non-compatible and is composed of a blend of thermoplastic resins or elastomers, and the non-compatible thermoplastic resins and elastomers are present as a non-uniformly distributed structure in the resin matrix. The packaging container or cap of this invention suppresses the lowering of flavor retention incident to the dissolving out of the oxygen absorbing agent or its oxidation product even after retorting sterilization. The preservability of the contents and flavor retention can be achieved for a long period of time. According to a preferred embodiment, the oxygen absorbing speed can be increased. After storage for a long time, or after heat sterilization, a rugged state does not occur. There can be formed the oxygen-absorbing resin composition and the packaging container having excellent outer appearance.

Abstract: A container is made of a laminated material that includes a tin layer which is exposed on the inner surface side of the container. Oxygen remaining in the container and included in the content is trapped by the reducing action of tin, and the content is prevented from being oxidized. Further, the remaining enzymes are de-activated and flavor can be excellently retained.
