Process for the preparation of a pulverulent composition and product as obtained

摘要

Method of preparing a non-hygroscopic pulverulent composition, includes a step for the spray drying, without an atomization support, of an aqueous solution containing at least one initially hygroscopic product, having a glass transition temperature ranging from 10° C. to 110° C., and a cryogenic fluid, especially a food-grade cryogenic fluid, or a mixture of cryogenic fluids, particularly chosen from liquid air, nitrogen and carbon dioxide, the aqueous solution being obtained by dissolving the cryogenic fluid in an initial aqueous solution containing the initially hygroscopic product.

1. A process for the preparation of a non-hygroscopic pulverulent lactulose composition, comprising a stage of spray drying, without an atomization support, of an aqueous solution of lactulose and a cryogenic fluid, or a mixture of cryogenic fluids, said aqueous solution being obtained by dissolving said cryogenic fluid in an initial aqueous solution containing 60% to 80% by weight of lactulose relative to the total weight of dry matter wherein the cryogenic fluid is at a pressure from 105 Pa to 20×105 Pa.
