The proposed method is based on the correlation of reducing sugars generated during the enzymatic process with the Schade reference assay. The polyacrylic film is charged with starch azure acting as a container for this substance; thus, the starch does not interfere in the measurement of reducing sugars, so that the diastase activity is easily calculated. The method has been contrasted with Schade method, showing good correlation and differences under 0.4% between methods in some honey samples. The polyacrylic film has great potential for the routine honey diastase activity assessment in small laboratories, dramatically reducing analysis time and cost. 0308-8146 http://hdl.handle.net/10259/5676 10.1016/j.foodchem.2021.129629 Honey Diastase activity Starch azure Polymer Film Polymer film as starch azure container for the easy diastase activity determination in honey
