Abstract
The further modification of acid modified flours and starches by reacting such acid modified flours, at a pH of less than about 3.0 with an alkylene oxide, preferably ethylene oxide, in order to scavenge residual acidity, raise the pH of the product and partially crosslink it. The thus created new crosslinked product is useful in gypsum wall board core binders and other applications.
Claims9
In the process of modifying flours and starches by treating such with acid to produce an acid modified product having a pH of up to about 2.5, when measured in a 10% water slurry;
- the improvement which comprises directly reacting said acid modified flour or starch with a lower alkylene oxide in a proportion sufficient to raise the pH of the reaction product up to, at least, about 3.5.
