Use of viscous compound to prevent substantial degradation of sensitive substance in pulverulent composition having particles including core having substance and compound as impregnating agent, and coating having compound as adhesive agent
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.
