PURPOSE:To provide a method for retaining the freshness of a material that has pores and is to be stored by which the period of retaining the freshness of the material to be stored can be prolonged over a long period and an apparatus for retaining the freshness. CONSTITUTION:The apparatus for retaining the freshness of a material to be stored is obtained by installing a weight converting part 5 for a sample in the interior of the apparatus body 2 for storing the material to be stored, sensing the opening degree of pores in the material to be stored in the apparatus body 2 with a controlling part 4 connected to the weight converting part 5 for the sample, drying or refrigerating the material to be stored with a drying and cooling part 3 based on the results sensed with the controlling part 4.
