PROBLEM TO BE SOLVED: To provide a system for maintaining freshness capable of securing ability of keeping freshness of fresh products during refrigerated preservation by produced ice without using sea water, and capable of maintaining the freshness of the fresh products for a long period of time.SOLUTION: Electrolysis is performed by an electrolyzed water generator 10 using water being fresh water, and alkaline electrolyzed water is generated. The electrolyzed water is made by an ice maker 20 to obtain electrolyzed water ice. The electrolyzed water and the electrolyzed water ice are stored along with the fresh products 60, and used for refrigerated preservation of the fresh products 60. Thus, oxidation action by oxygen in the fresh products can be suppressed by powerful reduction ability included in the electrolyzed water and the ice in addition to suppression of activity of bacteria leading to rottenness by refrigeration. Development of rottenness accompanying oxidation of cells in the fresh products 60 can be suppressed. The freshness of the fresh products can be maintained for a long period of time, extending a period to eat raw.COPYRIGHT: (C)2012,JPO&INPIT【課題】 海水を用いなくても、製造した氷による冷却保存中における生鮮物の鮮度を維持する能力を確保し、生鮮物の鮮度を長期にわたり保持できる鮮度保持システムを提供する。【解決手段】 真水である水を用いて電解水生成装置10で電気分解を行い、アルカリ性電解水を生成すると共に、この電解水を製氷装置20で製氷して電解水の氷を得、これら電解水と電解水氷とを生鮮物60と共に収納して生鮮物60の冷却保存に用いることから、腐敗につながるバクテリアの活動を冷却で抑制できることに加えて、電解水と氷の備える強力な還元力により生鮮物中の酸素による酸化作用を抑制でき、生鮮物60の細胞の酸化に伴う腐敗進行を抑えられ、生食可能な期間を延すなど長期にわたり生鮮物の鮮度を保持できる。【選択図】 図1
