Nowadays, food safety and functionality are drawing a lot of attention.
Watanabe Chemical provides safe and reliable raw materials which meet market needs for our customers.
As a general vitamin trading company, we import water-soluble and fat-soluble vitamins for food products, assure their quality, and supply them to food product manufacturers. In addition to vitamins we import, our core products are food grade vitamins from BASF (Germany), and food additives and seasonings from Mitsubishi Corporation Life Sciences.
We also focus on sales, development, and academic support for functional food ingredients that are compatible with vitamins. We promote the development of vitamin formulations through industry-academia collaboration for next-generation.
