The Salt Science Research Foundation

ABOUT SSRFThe Salt Science Research Foundation ( SSRF )


The Salt Science Research Foundation ( SSRF ) was founded in March, 1988 under the support of 22 organizations in Japan. The main purpose of the foundation of SSRF is to accelerate the research and development of salt by assisting economically and offering technological information.

Salt is not only a vital necessity for human life, but a very important raw material for many kinds of industries. Japan is not blessed with natural salt resource as rock salt, and also with the climate suitable for solar salt-making from sea water. The self-sustenance of salt in Japan, therefore, has been hard and has been realized by steady research and development of salt-making technology, for example the Irihama type salt-field technology and the ion-exchange membrane technology. The output of the salt industry in Japan is about 1.3 million tons per year which covers the demands for the food industries and several other industries except the chemical industries in Japan .

The technological subject on salt-making hereafter is to develop "a new process" for salt-making, both in the concentration process of sea water and in the crystallization process of salt, and some "utilization processes" of sea water resources in the salt-making processes. As salt is one of the fundamental inorganic chemical species, the development of the processes mentioned above will be applicable to improve the concentration and crystallization processes of various chemical species. Consequently, this activity of SSRF will contribute to the development of various chemical industries besides the salt-making industry. Development of utilization processes will, of course, contribute to the general approaches to utilize sea water resources directly.

On the other hand, the social concern on the effect of the intake of salt to health has become greater recently. The physiological and food scientific research is required to answer the concern.

This research should be carried out and be reported on the impartial stand-point because of the potential social effects. The public situation of SSRF is suitable to promote the research. Therefore, the activity of SSRF will contribute in answering the social concerns. The assisting research activity will be achieved by offering for public subscription of research themes. If necessary, a project-team will be organized for an especially important theme. SSRF intends both to accelerate the fundamental research other than that of a short-term target and to encourage young researchers in this activity.

The information activity will be achieved by collecting, analyzing and offering information. Various "databases" in the world will be fully utilized. Information is offered not only to researchers, but related organizations by a monthly journal. It will be desirable for SSRF to communicate with the information receptors intimately in order to accomplish this activity substantially.

The Research Operation Committee of SSRF which consists of authorities in various research fields will lead in the correct direction.
