Abstract: Warp sizing compositions and starches useful therefor are prepared from high amylose starches which are converted to a water fluidity viscosity within the range of 65 to 80 and then reacted with an etherification reagent to achieve a nitrogen content of 0.5 to 0.9% (dry basis).

Abstract: An improved method for producing granular, cold-water dispersible hydroxypropylated starch derivatives comprises reacting a granular starch base with propylene oxide in the presence of sodium acetate or another water-soluble salt of a selected carboxylic acid. The resulting starch product, which upon purification is free of toxic by-products and has no perceptible off-taste, finds use as a thickener in food as well as in non-food applications.

CPC classification number: C08B31/066
Abstract: Starch is phosphorylated by a virtually pollution-free, continuous process whereby an aqueous reagent solution of a tripolyphosphate, orthophosphate or pyrophosphate salt or a mixture thereof is sprayed onto a moist starch cake on a rotary vacuum filter in an amount sufficient to achieve efficient impregnation of the starch cake without losing significant levels of salt to the effluent. In a preferred embodiment, the reagent solution contains alkali metal tripolyphosphate salt and is obtained by diluting a concentrated solution thereof. The thus-impregnated starch is subsequently dried and heat-reacted by known procedures to produce an orthophosphate starch monoester.

Abstract: Highly substituted granular starches are prepared by reacting the starch in an aqueous system with a reagent capable of producing an acetal cross-linkage; reacting the resultant acetal cross-linked starch with a mono-functional esterifying or etherifying reagent under aqueous alkaline conditions and removing the acetal cross-linkages by treating under acid conditions. The highly substituted starches are particularly useful in operations, such as papermaking, wherein the cross-linkages can be removed and the starch readily dispersed during a relatively low pH starch cooking process.
Abstract translation: 通过使水性体系中的淀粉与能够产生缩醛交联的试剂反应制备高度取代的粒状淀粉; 在水性碱性条件下使所得缩醛交联淀粉与单官能酯化或醚化试剂反应，并通过在酸性条件下处理除去缩醛交联。 高度取代的淀粉在操作中特别有用，例如造纸，其中可以除去交联，并且淀粉在相对低的pH淀粉烹饪过程中容易分散。
