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.
