The invention provides a method for encapsulating a liquid, which method comprises the steps of providing a suspension of droplets of the liquid to be encapsulated; stabilizing the suspension of droplets with a surfactant; adding a layered inorganic material to the stabilized suspension; and subjecting the suspension to a treatment which establishes that a shell of a hybrid material is formed around the droplets, which hybrid material comprises at least part of the inorganic material and at least part of the surfactant. The invention further provides encapsulated liquid droplets obtainable by said method.

Method for encapsulating a liquid

Starch can be gelatinised more efficiently by a thermomechanical treatment, if a dialdehyde polysaccharide with a relatively low degree of oxidation is added to the starch. This thermomechanical treatment can be carried out at a temperature below 115 DEG C., or even below 100 DEG C., and with a high throughput rate. With this treatment a granulate or other semi-finished product is obtained that can be shaped to produce an article that has excellent dimensional stability in water. By adding dialdehyde polysaccharide with a low degree of oxidation to starch it is possible to blow transparent films based on thermoplastic starch which have improved mechanical properties.
