Riken Vitamin's Factory

Modern Equipment and Well-disciplined
People Guarantee Safety and Quality

The "seed" nurtured by long hours of hard work at our research and development facilities grows and is brought to fruition as a commercial product at our production facilities.
With our emphasis on health and nutrition, nothing is more important to us than maintaining the strictest standards of quality and safety through the latest, efficient facilities and vigilant quality control at all stages of development and manufacturing.


Soka Factory		Inaugurated in 1968 as Japan's largest powdered ramen soup stock factory, the Soka factory has expanded to meet demand and remains the backbone of our food products division. Renovated in 1989, it is now equipped with the most modern automated, computerized production system available. Expansion in 1992 added liquid processing capabilities that received widespread attention for their high degree of automation, and from which promptly came the highly successful "Non-Oil Super Dressing Aojiso."

Chiba Factory		Built in 1973, the Chiba factory employs our extensive know-how in food processing to produce a wide variety of food ingredients and compounds. In response to increasing demand, the facility has also begun production of natural vitamin E utilizing our renowned molecular distillation technology expertise. The Chiba factory's monoglyceride production line has been completely automated and a spray dryer line added, making it among the most ultra modern facilities.

Osaka Factory		It was here in 1959 that molecular-distilled monoglycerides were first produced commercially in Japan. Dedicated to monoglyceride distillation, the Osaka factory is a world class facility both in terms of its production capacity and advanced technology. With capabilities expanded to include both food products and industrial applications, the factory now exports to countries all over the world.

Kyoto Factory		Established in 1985, the Kyoto facility is chiefly engaged in research and production of natural colorants. Riken Vitamin first successfully extracted and refined a yellow colorant from gardenia in 1963 and a red colorant from a cultured red rice extract in 1977. We have continued to pursue further advanced in the field to keep a pace of recent rising demand for safe, natural colorants.

Tokyo Factory		Riken Vitamin's first factory, the Tokyo facility began production as a vitamin A dedicated facility in 1953 and today produces the vitamin in easily absorbed form for a variety of applications. The technological innovations by Riken Vitamin that made this vitamin stable even in oil form are now widely used.
