Abstract:
A method of preserving the one or more chemical and/or biological species in a polymer matrix comprising pullulan and trehalose is described. The method includes combining the one or more chemical and/or biological species, an aqueous pullulan and a trehalose solution and drying the resultant mixture to provide a solid polymeric matrix. A polymeric matrix comprising one or more chemical and/or biological species and its use, for example, on surfaces for food preparation, for food preservation and in biological preparations is also described.
