    • A process for producing thermally inhibited starch, specifically thermally inhibited non- pregelatinized granular starch, is described, resulting in a viscostable starch product. The process comprising providing an alkaline starch, specifically an alkaline non-pregelatinized granular starch,having a pH of at least 8; subjecting the starch to a hydrothermal treatment, specifically to obtain a hydrothermally treated non-pregelatinized granular starch, said hydrothermal treatment being at a temperature of 45 –200 °C with steam at a steam pressure of 0.1-15 bar or a gas mixture comprising water vapor at a partial water vapor pressure of 0.1-1 bar; dehydrating the starch, specifically the hydrothermally treated non-pregelatinized granular starch,to a moisture content of 2 wt% or lower and subjecting the starch to a thermal treatment by heating the starch to a temperature of 120 -190 °C to obtain viscostability,cooling and optionally further processing the starch.
    • 描述了一种生产热抑制淀粉的方法,特别是热抑制的非预胶化颗粒淀粉,产生可粘性淀粉产品。 该方法包括提供具有至少8的pH的碱性淀粉,特别是碱性非预胶化颗粒淀粉; 使淀粉进行水热处理,特别是获得水热处理过的非预胶凝粒状淀粉,所述水热处理的温度为45-200℃,蒸汽压力为0.1-15巴,或者气体混合物包含 部分水蒸汽压力为0.1-1巴的水蒸气; 使淀粉,特别是水热处理过的非预胶凝粒状淀粉脱水至含水量为2wt%或更低,并通过将淀粉加热至120-190℃的温度使淀粉经受热处理以获得粘度, 冷却并任选地进一步加工淀粉。
