Non-cryopreservation method such as food in the temperature zone below freezing point

摘要

It is an object of the present invention to provide a method of preserving unfrozen fish food or the like in a temperature zone below a freezing point.;The present invention relates to a method for preserving food or the like in an unfrozen state in an unfrozen region below a freezing point, characterized in that a rapid cooling treatment for cooling the food or the like to a vicinity of the freezing point of the food relatively rapidly at room temperature, And the slow-cooling treatment is carried out at a gentle cooling rate of 0.01 to 0.5C / hour up to the temperature below the freezing point.;According to the present invention, it is possible to preserve fish foods such as vegetables, fruit, fish, etc. with high freshness. In addition, it is possible to reliably suppress the freshness of the fish food inevitably occurring immediately after harvesting. Further, by combining the fish food treated by the preservation method of fish food of the present invention with ordinary low-temperature-level circulation transport means, it is possible to provide fish food with high freshness and high quality without decreasing freshness immediately after harvesting Can supply. In addition, the fish food or the like treated by the preservation method of the fish food of the present invention maintains the date at the consumption stage and can suppress the rapid deterioration of the quality as seen in the conventional product. In addition, a new type of frozen product that is not available in conventional products can be produced.
