Abstract: A crystallization method that comprises a step of providing a polyester comprising at least one 1,4:3,6-dianhydrohexitol unit, and a step of crystallizing this semi-crystalline polyester at a pressure of at least 600 mbar absolute. The method according to the invention makes it possible to strongly limit, or even eliminate, the phenomenon of polyester expansion during crystallization. Advantageously, the elimination of the expansion phenomenon through pressure conditions implemented according to the invention thus makes it possible to dispense with obtaining very fragile empty spheres that break when agitated and thus cause the formation of undesirable fine particles.

Abstract: The present application pertains to the field of cosmetics, more specifically the field of topical care of bad odors, by the action of a bactericidal and/or bacteriostatic topical composition, and of capturing odors. The topical composition according to the invention comprises at least one cyclodextrin, a 1,4-3, 6-dianhydrohexitol and/or a 1,4-3, 6-dianhydrohexitol derivative. It can be useful for the oral sphere, but also for areas of the skin where bad odors may develop due to microbial activity, namely the underarms, crotch and feet. Preferably, the topical composition of the invention is used for treating the oral sphere, most preferably for treating halitosis.

Abstract: A process for producing maltitol includes at least: producing a maltose syrup, by hydrolysis of a granular starch, in a first stage of liquefaction of granular starch to form a liquefied starch, followed by a stage of saccharification of the liquefied starch to which an aqueous solution of beta-amylase has been added, to form the maltose syrup; hydrogenating the maltose syrup to form an aqueous maltitol composition; and recovering the maltitol composition. The aqueous solution of beta-amylase also includes potassium sorbate, glycerol, and sodium carbonate.
Abstract: A directly compressible composition includes more than 30% by weight of allulose. The directly compressible composition can form tablets. A method for the manufacture of allulose granules includes: a step (a) of preparing a granulation liquid comprising allulose; a step (b) of granulating powdery allulose, by applying the granulation liquid obtained in step (a) onto moving powdery allulose; a step (c), simultaneous with step (b), of drying the granules obtained in step (b); a step (c?) of maturation of the granules obtained in step (c); and a step (d) of recovering the granules obtained in step (c) or (c?).
