PROBLEM TO BE SOLVED: To provide a method for retaining freshness of fresh food, which includes reliable peeling and removing of stuck contaminated substance to exert sterilization effect so as to secure the safety of a cut fresh food product and to suppress oxidization to keep the freshness and deliciousness of the fresh food product for a long period of time when producing the cut fresh food product.SOLUTION: The method for retaining freshness of the fresh food includes: sterilizing and cleaning the fresh food using calcined calcium aqueous solution peeling or coring the fresh food if necessary soaking the fresh food in antioxidant solution or spraying the antioxidant solution to the fresh food cutting the fresh food into pieces each with a prescribed size soaking the cut fresh food in freshness-keeping solution or spraying the freshness-keeping solution to the cut fresh food cleaning off the excessive freshness-keeping solution stuck to the surface of the cut fresh food taken out from the freshness-keeping solution using mixture gas of nitrogen gas/carbon dioxide storing the fresh food from which the excessive freshness-keeping solution is cleaned off, in a gas impermeable container together with deoxidizer simultaneously filling the container with the mixture gas of nitrogen gas/carbon dioxide and hermetically sealing the container.COPYRIGHT: (C)2013,JPO&INPIT【課題】生鮮食品のカット製品の製造に際し、付着している汚染物質を確実に剥離、除去して殺菌効果を発現して当該製品の安全性を確保し、酸化を抑制して鮮度と旨みの長期保持を可能にする方法を提供する。【解決手段】生鮮食品を、焼成カルシウム水溶液を用いて除菌清浄処理し、必要に応じて皮を剥き又は芯を抜き、酸化防止用溶液に浸漬又は吹付け処理し、所望サイズにカットし、鮮度保持溶液に浸漬又は吹付け処理し、鮮度保持溶液から取り出したカットした生鮮食品の表面に付着している過剰な前記鮮度保持溶液を、窒素ガス・二酸化炭素の混合ガスを用いて落とし、過剰な鮮度保持溶液を落とした生鮮食品を脱酸素剤と共にガス不透過性容器に収納し、同時に前記容器内に窒素ガス・二酸化炭素の混合ガスを充填して密封する。【選択図】なし
