DD Williamson (DDW) recently completed the acquisition of the food coloring product line and related processing equipment from Danisco USA, a part of DuPont Nutrition & Health. DDW’s expanded natural coloring operation in Port Washington, WI has manufactured all products following the transaction in December 2013. The acquisition broadened DDW’s portfolio of natural color solutions for customers and positioned DDW as the largest manufacturer of annatto-based food colorings in North America.
