High-purity DNA products made from salmon soft roe

Food and food additives

Daiwa Fine Chemicals was originally a trading company specializing in food-processing chemicals. In the half-century since that time, we have served the food, restaurant, and health food industries with ingredients and additives with a focus on natural products. Now, all eyes are on one of our current projects, namely the manufacture of a high-purity DNA-related products extracted from the soft roe of salmon.

High-purity DNA products made right here in our factories
At our Kamaishi Factory, a component of Daiwa Fine Chemicals (Laboratory), we have succeeded in establishing the technology to extract and powderize deoxyribonucleic acid (DNA), protamine components, and soft roe proteins from the soft roe of salmon caught off the Sanriku shore in Iwate Prefecture. High-purity DNA products manufactured here are used in a variety of applications including health foods, cosmetics, and as materials for pharmaceutical intermediate products.
Moreover, Kamaishi Factory is working in cooperation with the Iwate Industrial Research Institute, succeeded in establishing a method of extracting fibrous high-polymer DNA without compromising the original double helix structure. Currently, we supply this DNA to research groups in various universities and companies as a research compound for studies into industrial materials.
Natural food ingredients and Food processing materials
Thanks to our accumulated expertise, we are able to supply customers with the best natural seasoning ingredients, including soy sauce, kombu seaweed, bonito, and miso, from painstakingly selected producers. Moreover, for the food and restaurant industries, we provide processed materials to promote efficiency and reduce labor in food preparation.
At the sametime, we have joined forces with overseas food makers to import potatoes and beans from Myanmar and other countries in order to ensure a supply of high-quality, low-cost processed ingredients.
