The paper presents the results of a study on the water absorption capacity and solubility of biodegradable starch foams produced with single-screw extruder TS-45 with L/D=12. Two different moulding dies were used: one with a circular hole with the diameter of 3 mm and one with a ring hole with the inner diameter of 5 mm. During the extrusion process, the temperature of the cylinder ranged from 80...
The results of measurements of susceptibility to biodegradation and the effect of storage in soil on the mechanical properties of thermoplastic starch films obtained from blends of starch, glycerol and emulsifiers. Studies have shown a varied influence of the blend compositions, extrusion conditions and storage on the scope and efficiency of biodegradation of the products.
The simplest method of physical modifi cation of starch is extrusion-cooking. Changes of the extruder efficiency and specific mechanical energy (SME) during extrusion-cooking of potato starch are presented in the paper. Extrusion-cooking process was characterised by good efficiency. The output depended mainly on the extruder screw speed and starch moisture content, less on process temperature. It...
