The invention relates to foodstuff and animal feed which contain resistant starch on the basis of water-insoluble linear &#x3b1;-1,4-D-glucans. The invention also related to the utilization of resistant starch on the basis of water-insoluble linear &#x3b1;-1,4-D-glucans as medicaments.

&#x3b1;-Amylase-resistant starch for producing foodstuff and medicaments

The invention relates to a process for increasing the content of &#x3b1;-amylase-resistant starch (RS content) of a polysaccharide wherein

Method of increasing the &#x3b1;-amylase-resistant starch content (rs content) of a polysaccharide, polysaccharides, the use thereof and food containing said polysaccharides

The invention relates to a gel based on poly-&#x3b1;-1,4-D-glucan and, optionally, on starch as well as on a swelling agent, to a method for the production thereof, and to the use of a gel of this type.

Gel comprised of a poly-&#x3b1;-1,4-glucan and starch

The present invention relates to a sun protection product which contains microparticles as the active agent, wherein the microparticles comprise water-insoluble linear polyglucan.

Sun protection product with microparticles on the basis of water-insoluble linear polyglucan

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. 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.

Compositions comprising starch and/or modified starch and plasticizers

The present invention relates to a method for preparing smooth-surface spherical microparticles which are completely or partially made of at least one water-insoluble linear polysaccharide. This method involves dissolving the at least one water-insoluble linear polysaccharide in a solvent or a mixture of solvents, introducing the solution into a precipitation agent or a mixture of precipitation agents, optionally cooling the mixture thus obtained, and separating the microparticles thus formed. The precipitation agent used consists of at least one water-soluble cellulose derivative. This invention also relates to microparticles obtained according to this method.

Method for preparing smooth-surface spherical microparticles completely or partially made of at least one water-insoluble linear polysaccharide and microparticles produced according to this method

Microparticles with a uniform spherical shape and a very narrow size distribution are described. They consist wholly or partly of a linear water-insoluble polysaccharide, preferably of 1,4-&agr;-D-polyglucan, and may contain other, in particular biodegradable, polymers and/or active substances. They are suitable inter alia for the controlled delivery of active substances. They are prepared by dissolving 1,4-&agr;-D-polyglucan or the polysaccharide in a solvent, introducing the solution into a precipitant, cooling the mixture and removing the particles formed.

Spherical microparticles containing linear polysaccharides

The invention relates to a production method of &agr;-amylase resistant polysaccharides with high RS content, comprising the following steps: a) producing a paste of water-insoluble poly-(1,4-&agr;-D-glucan) and water; b) heating the paste; c) cooling off and retrogradation of the past at a temperature that is lower than the temperature of the heated paste and d) optionally drying the resulting product.

&agr;-Amylase-resistant polysaccharides, production method, use and foods containing these polysaccharides

The present invention relates to the utilisation of water-insoluble linear poly-&agr;-glucan as UV filter, e.g., in sun protection products or in cosmetic as well as medical preparations. The invention also relates to a sun protection product which contains a biotechnically produced, water-insoluble linear poly-&agr;-glucan as UV filter.

Method of filtering UV- light

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.

Method for the production of small spherical particles containing at least one water-insoluble linear polysaccharide

The invention relates to a controlled release tablet which in part or as a whole contains water-insoluble linear polysaccharides, preferably the polysaccharide poly(1,4-&agr;-D-glucan), in the form of microparticles, as retardation material. The tablet is also capable of controllably releasing an active agent.

Slow release tablet prepared from linear water-insoluble polysacchrides

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.

Compositions containing starch and/or modified starch and plasticisers

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.

Method for the production of spherical microparticles consisting totally or partly of at least one water insoluble polyglucan containing branches and microparticles produced according to said method

The present invention relates to a topical preparation containing spherical microparticles as the essential component, wherein the microparticles comprise water-insoluble linear polyglucan.
