Estaan is a natural complex of polyphenols, extracted from plants. The ingredients are derived from ten different plants from three continents. All natural, without synthetic components. Elaborate tests have preceded the application. Wine is the first product in which Estaan is used. But it can also be used as an antioxidant in silver onions, mustard, cosmetics, sliced vegetables, dried fruit, meat substitutes and potato chips. 

The developers call the substance the food preservative of the future. ‘The biggest breakthrough in the food preservative history.’ The plant formulation is based on a sequential multiphase separation technique, followed by purification steps. A process in which all active components stay intact.
