  • Sorbitol, Maltitol, Xylitol By 1931, Deutsche Hydrierwerke (DHW) in Rodleben/Germany patented and initiated the world’s first production of fatty alcohols based on the evolving technology of catalytic, high pressure hydrogenation.

    The experiences of DHW in hydrogenation technology during the next decades resulted in further product developments: in 1965, DHW started the production of its first liquid Sorbitol starting from vegetable raw materials. By developing special reactors using the spray drying technology, DHW launched in the forthcoming years a comprehensive series of spray dried Sorbitol. Recently, new polyols such as Maltitol and Xylitol have been added to the sugar alcohols range offering thus a broader product portfolio to our customers and to the market. All products, liquid and spray dried Sorbitol, spray dried Xylitol and liquid Maltitol have become indispensable as a sugar substitute in modern nutrition and in diabetic products. They are used in numerous other application fields including quality foods, confectioneries, personal care, pharmaceuticals and in some industrial applications.

    In 1991, DHW was incorporated in the worldwide network of research and production facilities of our oleochemical group. With the creation of Ecogreen Oleochemicals in 2001, DHW reinforced its position as a global producer and supplier of unsaturated fatty alcohols, primary fatty amines, sorbitols and other sugar alcohols as well as of a new range of speciality fatty esters and ethers.

    Longtime R&D experience combined with additional synergies from global oleochemistry allows DHW to present itself as a strong and reliable partner for industrial cooperation. Starting from vegetable based raw

    materials DHW in Rodleben offers tailor-made oleochemical derivatives to be used in the production of nutritional products, cosmetic and pharmaceutical goods as well as additives for industrial purposes.

    Progress from nature

    Over the years, as worldwide awareness for environmental issues have grown, gentle processing technologies and the use of renewable resources have become increasingly important. Our technological expertise making use of natural ingredients for the production of chemical substances qualifies DHW at Rodleben to fulfill its obligations in meeting the requirements for a sustainable, ecologically-sound world. The concept of a chemical production site based on human needs and environmental awareness is already reality within our company today.

    DHW sugar alcohols are based on renewable raw materials.

  • Sugar alcohols belong to the group of polyhydric alcohols and are produced by a catalytic hydrogenation of natural carbohydrates. They are naturally present in smaller quantities in fruits as well as in certain kinds of vegetables.

    DHW sugar alcohols comprise the products Sorbitol, Xylitol and Maltitol.

    Sorbitol is a hexavalent sugar alcohol and is derived from the catalytic reduction of glucose

    Xylitol is produced by catalytic hydrogenation of the pentahydric alcohol xylose

    Maltitol is obtained of natural disaccharide maltose after catalytic hydrogenation

    DHW offers tailor-made Sorbitols and Xylitol as spray dried products with unique advantages in their usage for a number of applications. Maltitol and Sorbitol are available as 70 % aqueous solutions.

    Specific Properties of DHW Sorbitol and Xylitol Spray Dried

    Unique benefits for your applications by specific particle structures

    By means of the specifically developed spraying technology, unique application benefits can be achieved by the

    formation of a specific particle structure.

    Properties of Sorbitol, Maltitol and Xylitol

    Functional properties

    • Sweetening power Xylitol has the same sweetening power as sugar. Sorbitol and Maltitol solutions are slightly less sweet

    • Cooling effect Sorbitol and Xylitol have – caused by their negative solution heat and their good solubility in water – a pleasantly sweet and cooling taste. Maltitol is pleasantly sweet only

    • Cariogenity Non-cariogenic effect when compared to sugar Sorbitol and Maltitol are significantly slower degraded to acids. Xylitol is not fermented by most of the micro-organisms in the oral cavity

    • Dietetics Sorbitol, Maltitol and Xylitol are excellent dietetics for diabetics because of their insulin- independent processing in the human body and their toxicological harmlessness

    • Metabolism Sugar alcohols are metabolized and assimilated partially only. Large quantities reach the large intestine, and are fermented there by the existing micro-flora. When consuming large quantities (20 g and more), possible side effects like flatulence or a laxative effect may occur

    • Caloric value Because of their slower absorption, sugar alcohols have a lower caloric value. In the EU, 2.4 kcal/g are fixed for all sugar alcohols

    Application advantages

    • Excellent compressibility and tablet formation
