摘要：Under-ground storage of rice grain was experimented at an abandoned mine in Shikoku Island, basing on the same principle of the under-water storage that was carried out at Lake Biwa from April 14th of 1969. The packaging materials for the under-ground storage of rice were endowed with the same features as those of the materials used for the under-water storage. The packaging system was consistect uf three layers; inner, middle and outer bags. A particular attention was paid for the outer bag to avoid from the possible ravages of field rodents. Several kinds of plastic materials were tested in all combinations of two for the inner bag, five for the middle bag and three for the outer bag. The gas and water-vapor transmission of several laminated films used in this experiment and the results of drop test for the middle bags made of them were shown. Plastic bottles were also tested as another type of the storage container. Eighteen bags and two plastic bottles containing brown rice were transported by truck, ropeway and mine truck to the storage place, 570m deep in a gallery, where the air temperature ranges from g to 11.5°C in one year, while the relative humidity is over 94% due to underground water. After every year, the stored rice is to be tested by physical, biological and organoleptical means and the results to be compared with the rice stored open under the conventional storage condition.
