KANSAS CITY — Surveys continue to show the rising popularity of clean label claims. Food and beverage companies may take several avenues to achieve such claims: no artificial preservatives, flavors or colors; organic; and non-G.M.O. “No preservatives” were the top clean label claim in two surveys. Ways to work with clean label preservatives, including alternatives to calcium propionate, should be found at the International Baking Industry Exposition scheduled for Sept. 7-11 in Las Vegas. Suppliers of flavors and colors, meanwhile, are turning to organic certification in their clean label efforts.
