Abstract

An encapsulated material containing an oxidation-sensitive core is covered by at least a dried phospholipid layer, and contains at least one phytosterol in the core, the phospholipid layer or in a further layer or layers. By using microencapsulation, oxidatively unstable materials may be provided with a synthetic protective barrier and rendered less susceptible to oxidative degradation.
