摘要： The invention concerns the use as surface-active agent of a fructan N-alkylurethane (I) which is composed of saccharide units of general formula (II) A(O—CO—NH—R)s (II) wherein A represents a fructosyl unit (F) or a terminal glucosyl unit (G) of said fructan, being a levan or an inulin, with a degree of polymerisation (DP) of minimum 3, (O—CO—NH—R) represents an N-alkylaminocarbonyloxy group replacing a hydroxyl group of the saccharide unit A, wherein R represents a linear or branched, saturated or unsaturated alkyl group containing from 3 to 22 carbon atoms and any mixture thereof, and s represents the number of N-alkylaminocarbonyloxy groups per saccharide unit which is expressed as degree of substitution (DS), and said DS has a value ranging from 0.10 to 2.0. The invention further relates to novel fructan N-alkylurethanes (I), in particular inulin N-alkylurethanes (I), and a method for their manufacture. The fructan N-alkylurethanes (I) have good to excellent surface-active properties in combination with good biodegradability and are suitable as surfactants for use in household and industrial applications, e.g. as detergents, emulsifiers, emulsion stabilizers, foaming agents, foam stabilisers, dispersants and wetting agents.
摘要翻译：本发明涉及由通式（II）的糖类单元构成的果聚糖N-烷基氨基甲酸酯（I）的表面活性剂的用途，其中A表示所述果聚糖的果糖基单元（F）或末端葡糖基单元（G）（DP）为3，（O-CO-NH-R）表示取代糖单元A的羟基的N-烷基氨基羰基氧基，其中R表示直链或含有3至22个碳原子的支链，饱和或不饱和的烷基及其任何混合物，s表示以取代度（DS）表示的每个糖单元的N-烷基氨基羰基氧基的数目，并且所述DS具有值范围从0.10到2.0。本发明还涉及新型果聚糖N-烷基氨基甲酸酯（I），特别是菊糖N-烷基氨基甲酸酯（I）及其制备方法。果聚糖N-烷基氨基甲酸酯（I）具有良好至优异的表面活性特性以及良好的生物降解性，并且适合用作家用和工业应用的表面活性剂，例如，作为洗涤剂，乳化剂，乳液稳定剂，发泡剂，泡沫稳定剂，分散剂和润湿剂。

摘要： The present invention describes a protein having glucosyltransferase activity. This protein is derived from lactobacilli, which are food-grade microorganisms with the Generally Recognized As Safe (GRAS) status. The protein produces a glucan with a unique structure having 4-linked, 6-lined and 4,6-linked anhydroglucose units or in the presence of suitable acceptors, oligosaccharides. According to the invention lactobacilli capable of producing this glucan using the novel glucosyltransferase can be used as a probiotic or symbiotic.
