Response surface experiment optimize natural edible fungus paper production process and physical properties research

Response surface methodology( RSM) and univariate was used to optimize natural edible f ungus paper production process. The effects of main parameters including the thickness of the coating,liquid ratio,agaric powder particle size,which affected the modified process were studied. Using texture analyzer fungus flakes hardness,cohesion,elasticity,adhesive and chewing gum and other physical indicators were measured.Results showed that the factors affecting the order from large to small was agaric powder particle size>watermaterial ratio>coating thickness. The results showed that when the thickness of the coating was 1.1 mm,watermaterial ratio was 15.2∶1 m L/g and agaric powder particle size was 200 mesh. The sensory score could reach 97.2. Under the process conditions,physical properties of the black fungus paper were hardness 5.42,cohesiveness 1.71,cohesion 1.24,elastic plastic viscosity 5.35,chewiness 1.37.
