The application belongs to the field of oral composition and food application, and provides a composition containing choline alfoscerate and application thereof. The composition takes L-alpha-choline alfoscerate as a liquid phase component, takes a complex core formed by pyrroloquinoline quinone disodium salt and cyclodextrin as a core, forms a multi-layer core-shell particle through core particle construction and layer-by-layer assembly of gelatin and sodium alginate, and is cooperatively configured with a dual-phase or dual-cavity storage mode. Therefore, the storage stability of the active ingredient, the integrity of the particle structure and the active release performance when used are considered, the adverse effects of environmental exposure are reduced, and the use convenience is improved. The composition can solve the problem that the memory-improving function and storage stability are difficult to be considered, and the particle structure integrity and the active release performance are restricted by each other, and is suitable for memory-improving food development and application.
