FIELD: chemistry.

SUBSTANCE: invention relates to a layered composition for microencapsulation of heat-sensitive biologically active material. Layered composition for a sensitive active material comprises a core for containing active material and a plurality of layers surrounding said core. Each layer is specific in relation to temperature and each layer includes one or more materials which are suitable for ingestion. Said several layers include a core layer for at least partially surrounding said core and at least one additional layer for at least partially surrounding said core layer. Each layer contains a polymer with a melting point and melting point of said polymer of said core layer is lowest of all melting points of all layers. Melting point of said polymer of at least one of said additional layer is higher than said melting point of said core layer. Said layers include a first coating layer, which is said core layer and to adjoins said core, containing at least one first material with phase transition (PCM) with melting point lower than 60 °C and higher than 20 °C; a second coating layer containing at least one second material with phase transition (PCM) with melting point lower than 60 °C and higher than 20 °C, which at least partially covers core which is coated with first coating layer. Second PCM has melting point higher than melting point of first PCM, and melting point of polymer of each additional layer is higher than melting point of polymer of previous layer in order of application of said layers. Layered composition is used as an additive to a food product.

EFFECT: invention provides a long storage life of thermal sensitive biologically active material, for example probiotics.
