FIELD: chemical technology.SUBSTANCE: invention relates to a method for preparing alkaline- and thermostable composition based on sugar alcohols of the optical density less or equal to 0.100 in S-test. Method involves treatment of sugar-base composition with strong-base anion-exchange resin in hydroxide form at temperature 30-100°C. Method provides decreasing consumption of chemical reagents and providing carrying out the combined a single-step process for alkaline stabilization and decolorizing.EFFECT: improved preparing method.18 cl, 7 tbl, 8 ex

(RU)
Изобретение относится к способу приготовления щелоче- и термостабильных композиций на основе сахарных спиртов с оптической плотностью менее или равной 0,100 в S-тесте, согласно которому композиция на основе сахарного спирта обрабатывается сильноосновной анионообменной смолой в гидроксидной форме при температуре от 30°С до 100°С. Способ позволяет сократить расход химических реагентов и обеспечить комбинированный одностадийный процесс щелочной стабилизации и обесцвечивания. 17 з.п. ф-лы, 7 табл.
