Phase separation and bloom in fat-based fillings lead to poor shelf stability and texture loss. These formulations engineer the lipid network structure to maintain homogeneity and mouthfeel.
The inclusion of aerated confectionery and expanded cereal products indicates a focus on the instability of gas bubbles within a lipid-based network. Preventing the loss of volume or texture due to internal pressure changes or mechanical weakness is critical for shelf-life and sensory quality.
