High-Purity Activated Carbon "SHIRASAGI" for Purification of Raw Materials and Active Ingredients in Dietary Supplements and Functional Foods
Osaka Gas Chemicals' SHIRASAGI brand activated carbons are treated by advanced cleaning technology to meet the purity levels required during production of nutraceuticals and foods with functional claims products EPA & DHA , Indigestible Dextrin and so on.
EPA and DHA are made from fish oil, it's prone to oxidation, which can lead to flavor deterioration (odor generation) due to the generation of by-products and impurities such as various oxides and aldehydes.
Resistant dextrin is made from cornstarch, and is prone to contaminants and impurities and coloring during the refining process.
Osaka Gas Chemical's Shirasagi activated carbon comes in a lineup of various grades suitable for selective adsorption of a wide range of target molecules, and can decolorize at the same time as adsorption, allowing for efficient product production.
Osaka Gas Chemicals' SHIRASAGI activated carbon brand began mass production in 1937 under Takeda Pharmaceutical Company Limited, a pharmaceutical manufacturer. Since then, through continuous research and development, accumulating specialized knowledge and know-how, it has achieved the top market share in the Japanese pharmaceutical industry and a high share in the food and chemical industries.
Osaka Gas Chemicals is a leading activated carbon producer. Quality and supply stability is achieved via procurement and selection of raw materials and manufacturing at multiple locations globally.
