  • Patent number: 4473620
    Abstract: Disclosed are free flowing, solid, antioxidant particles comprising butylated hydroxyanisole encapsulated within an edible polymeric coating. The coating is adapted to release the butylated hydroxyanisole when the particles are in contact with vegetable oil or molten fat. The process for preparing these antioxidant particles includes establishing a molten butylated hydroxyanisole as droplets in a liquid dispersion containing a dissolved film forming edible polymer. The liquid dispersion is cooled below the melting temperature of the butylated hydroxyanisole droplets thereby causing the dissolved polymer to form an encapsulated film around the solidified droplets and surface drying the solidified droplets.
