    摘要： Compositions are described, based on starch and/or on modified starch and comprising, as plasticizers, polyhydroxycarboxylic acids derived from aldoses and/or from ketoses, in particular from pentoses and hexoses, or comprising lactones of these acids such as &dgr;-caprolactone. The materials can be processed thermoplastically to give shaped articles which are biodegradable and physiologically nonhazardous. They may be used as packaging or casing for food or drink or pharmaceutical products, or also for the controlled release of active substances, or else for producing temporary protective coatings.

    摘要： The present invention relates to a method for the production of small spherical particles consisting totally or partly of at least one water-insoluble linear polysaccharide by dissolving the at least one water-insoluble polysaccharide in a solvent or a solvent mixture, introducing the solution into a precipitating agent or a precipitating agent mixture, optionally cooling the mixture thus obtained and separating the formed small particles, wherein at least one poly alpha D-glucan soluble in hot water is used as auxiliary agent for precipitation. The invention also relates to the particles obtained according to said method.

    摘要： The invention relates to a method for the production of spherical microparticles consisting totally or partly of at least one water-insoluble polysaccharide, wherein the at least one water-insoluble polysaccharide is dissolved in a solvent or solvent mixture, the solution thus formed is introduced into a precipitating agent or precipitating agent mixture, the mixture obtained is optionally cooled and the formed microparticles are separated. The invention is characterized in that the water-insoluble polysaccharide is selected from a polyglucan containing branches with a degree of branching higher than zero and no higher than 8% and a mixture of a polyglucan containing branches and a linear polysaccharide, wherein the proportion of polyglucan containing branches in the mixture is at the most 30% by weight in relation to the overall weight of the polysaccharide and the polyglucan.
