摘要:
Use of at least one viscous compound, whose viscosity is greater than 5 Pa.s ->; 1>;, for preventing the substantial degradation of sensitive substance at a temperature of 20-100[deg] C, pressure of 10 6>;-10 7>;Pa and/or a relative humidity of 60-100% in a pulverulent composition comprising the powder particles that include: a core containing the sensitive substance and at least one viscous compound as impregnating agent of the substance, and a coating, for the core, containing at least one viscous compound as adhesive agent, is claimed. Independent claims are included for: (1) a stable pulverulent composition comprising the particles comprising a core containing at least one sensitive substance (that is sensitive to temperature of 20-100[deg] C, pressure of 10 6>;-10 7>;and/or a relative humidity of 60-100%) and at least one viscous compound in impregnating agent; and a coating, for the core, comprising at least one viscous compound in adhesive agent, where the sensitive substance is not an enzyme intended for consumption by animals or human; (2) preparation of the composition comprising microgranulation of a mixture of sensitive substance, the support and the impregnation agent for obtaining the core and coating the core with adhesive agent; and (3) a food composition comprising the pulverulent composition in which the sensitive substance has at least 80%, preferably at least 90%, of initial activity and the substance is not intended for human or animal consumption, and at least one food product.
