Milk-Derived Sphingomyelin Composition for Storage Flavor Stability

Silicon dioxide acts as an intermediary substance that prevents direct interaction between milk-derived sphingomyelin and oxygen/moisture in the environment. The adsorbent material absorbs excess moisture and oxygen that would otherwise accelerate flavor deterioration, thereby maintaining both physiological function and sensory quality during storage.

The patent creates a protected microenvironment within the solid composition by incorporating adsorbent materials that effectively remove oxygen and moisture, creating an inert-like atmosphere that prevents oxidative rancidity and hydrolytic degradation of the milk-derived sphingomyelin, thus preventing flavor deterioration while maintaining stability.

Silicon dioxide serves multiple functions simultaneously: it acts as a filler to maintain physical structure, an adsorbent to control moisture and oxygen, and a flavor protectant. This multi-functionality allows long-term storage stability to be achieved without proportionally increasing formulation complexity, as one ingredient addresses multiple degradation pathways.

The patent optimizes the amount of silicon dioxide within a specific range (0.5-5 mass%) to achieve the desired balance between storage stability and formulation simplicity. By controlling this key parameter, the formulation achieves effective flavor protection without excessive complexity in composition or processing.
