Optimization of edible Alyssum homalocarpum films for physical and mechanical properties

The effect of dry material, glycerol and ratio of water to seed in Alyssum homalocarpum films on their thickness, transparency, moisture content, tensile strength, elongation and water vapor permeability was investigated using mixture response surface methods. Dry material and glycerol were important factors influencing tensile strength, elongation and water vapor permeability. Ratio of water to seed had little effect on physical and mechanical properties. The statistical methodology used determined the following optimal conditions for use in the casting process: 20% glycerol, 0.3% dry material content and Ratio of water to seed was 2.5.
