Publication number: 20070059340Abstract: Disclosed are processes for stabilizing omega-3 fatty acids for use in food products. The processes permit creation of a variety of food forms and food ingredients that contain omega-3 fatty acids like docosahexaenoic acid and eicosapentaenoic acid wherein these foods and food forms are stable for months without developing fishy aromas or tastes. This stability enables the incorporation of omega-3 fatty acids into food forms such as ready to eat cereals, trail mixes, chips, granola bars, toaster pastries, baked goods, cookies, crackers, fruit pieces and fruit leathers. The processes utilize a zein coating to protect and stabilize the omega-3 fatty acids.Type: ApplicationFiled: September 11, 2006Publication date: March 15, 2007Inventors: Anthony Bello, Norbert Gimmler, Pradip Roy
