Abstract

Описывается способ для уменьшения вязкости полисахаридов, таких как крахмал, обработкой перекисью водорода в присутствии ацилированного полисахарида в качестве активатора. Ацилированный полисахарид в основном применяется в количестве, эквивалентном, по крайней мере, 1 ацильной группе на 100 единиц моносахарида. Перекись водорода преимущественно применялась от 2-20 вес.% по отношению к суммарному полисахариду и ацилированному полисахариду.Международная заявка была опубликована вместе с отчетом о международном поиске.A method is described for reducing the viscosity of polysaccharides, such as starch, by treatment with hydrogen peroxide in the presence of an acylated polysaccharide as an activator. The acylated polysaccharide is mainly used in an amount equivalent to at least 1 acyl group per 100 units of monosaccharide. Hydrogen peroxide was predominantly used from 2-20 wt.% With respect to the total polysaccharide and the acylated polysaccharide. The international application was published along with an international search report.
