Incorporation of pickering emulsions into starch-based materials to produce phase-change composites

The phase change materials (PCMs) used are alkanes with melting temperatures close to ambient (6°C-18°C). By encapsulating them in a Pickering emulsion, they can be integrated into the hydrophilic starch matrix to form composite materials.

When melted, the MCP becomes a source of cold production (due to its latent heat of fusion) and enables the product to be kept for a certain period of time under the right storage conditions (regulatory temperature). This PCM must both provide thermal inertia in the storage temperature range (0-4°C, close to the product) and limit the heat flow entering the packaging (thermal resistance at ambient temperature).
