The Riverside Company, a private equity firm, completed an investment in National Flavors, a manufacturer of flavours for use in the food industry. Financial terms were not disclosed. "The market for flavor manufacturing businesses is highly attractive, and it is a great time for founders to sell. During our investment period, we will look to strengthen NF’s research, development and application capabilities through organic and inorganic growth initiatives to continue delivering innovative custom flavors and leading customer service. We are actively pursuing add-ons of other leading flavor houses to complement NF,” Loren Schlachet, Riverside Managing Partner.
