Whipping cream, typically containing 35%-40% milkfat, is a complex
oil-in-water emulsion system that transforms into aerated dairy foam upon
whipping. Adequate whipping performance and product quality depend on
controlled viscosity, efficient air incorporation, desirable sensory
properties, and stability during refrigerated and freeze–thaw storage. In
low-fat whipped cream systems (<30% fat), emulsifiers are commonly
employed to promote partial fat destabilization, which in turn stabilize air
bubbles. However, emulsifiers such as lactylated monoglycerides, sodium
stearoyl lactylate, mono- and diglycerides, and polysorbate 80 are
increasingly excluded from formulations due to clean-label considerations.
This would lead to prolonged whipping time or inadequate whipping, resulting
in a soft texture and poor shelf stability, resulting in an unpleasant
eating experience.
To overcome these limitations, this study proposes an emulsifier-free,
clean-label formulation strategy based on the synergistic structuring
effects of starch and selected hydrocolloids. The resulting
starch–hydrocolloid network structures compensate for reduced fat content by
providing the suitable continuous-phase viscosity, supporting air bubble
stabilization, and improving foam resilience (Figure 1). This approach
enables the development of clean-label whipped cream formulations containing
15–25% fat with improved whipping performance, enhanced refrigerated and
freeze–thaw stability, and an improvement in fatty mouthfeel. These findings
highlight the critical role of starch–hydrocolloid interactions in enabling
successful clean-label reformulation of aerated dairy systems.
