Final Report Summary - CONTROLLED RELEASE (New controlled release systems produced by self-assembly of biopolymers and colloidal particles at fluid-fluid interfaces)
The research strategy of the project is summarised by '... structure design (structure engineering) of the interior and the surface structures of the capsules' with the aim to deliver capsule for flavour-release by manipulate the interior by interface or vice versa.
One major effort during the first year was to identify suitable model systems to address our scientific goal and to eventually narrowing the choices of material to be investigated during the second and third year of the project. The meetings in Vlaardingen and later on in Munich were used to identify suitable materials, material combinations, experimental setups, and methods to model and analyse the experimental findings.
As major achievements of the entire project we can summarised the flowing items:
- linking the material properties and structure of the shell and the interior in a modelling effort;
- production of multi-shell containers for flavour release;
- establishing a production method for solid and hollow zein protein spheres flavour release;
- utilisation of heat-set biopolymers in confinement for flavour release purposes;
- establishing a robust and versatile microfluidics environment to study container morphology and dynamics;
- description of phase separating of biopolymers in confinement with the Soft Solid model;
- establishing of comprehensive methods to study the flavour release by means of the FRAP method;
- screening of suitable container wall materials from proteins, hydrocolloids, and colloidosomes.
